How to make a spreadsheet (be it Google Sheets or MS Excel) secure?


Recommended Posts

Password encrypt the documents you update and print to PDF to give to family members and that way then can't modify any data.  If you get hit by a bus then they'll need to take the latest PDF they received and give it to the next person that'll fill your roll.

 

I have a client who manages the "family money" of a prominent local family and it wasn't this hard to do this when he asked for something similar. You're over complicating things...

I'll talk you through the steps and you can tell me where i went wrong.

Bear in mind that i am a typical caveman who can't(doesn't) read instructions. I know i should. My impatience is something that irritates the wife endlessley so i KNOW i'm impatient.

 

But before this, can i ask - is there an encryption software that you can use that DOESN'T need to be installed on the machine that is trying to open the file, or will it always need to be installed on there? (Which may make this tricky if they forget what software they need to then go download, or that software no longer exists).

 

* Went here: https://www.gnupg.org/download/index.html

* Saw the stuff saying "source code" and "To use them you need to build the binary version from the provided source code" and thought that sounds well beyond my capabilities. Let's scroll further to see if something looks appealing...

* Got to [GnuPG binary releases] & downloaded [Gpg4win] next to where it said Windows.

* Installed the thing and got to the screenshot i uploaded earlier.

* Looked at it and thought WTF now?

* As i want to encrypt something i looked for something saying encrypt so clicked "sign/encrypt" in the top left, found the file and clicked open.

Got that one and ticked the bit that i drew a tick on as i realised when i took that screenshot it was unticked.

 

* Created a password

* It 'encrypted it'

* Went to click open the new file but wasn't asked for a password.

Save or discard. I just want to open the damn thing.

 

And i saw no pages like Budman showed where you can set how long it stays encrypted for or whatever.

There'll be no 'next person' unless they learn themselves which they have no interest in doing because for most people moving money around to make it work as hard as it can is "too much work" and "boring". Weird that i have no patience yet i have time to help them all with this. I'm not really that knowledgable in many areas so i like to help where i can.

So i get told...very very frequently. So frequently in fact that i just shut off to it now and say yeah right ok to those who can't suggest a suitable alternative.

 

Some (on this topic) think putting it down on paper is a 'suitable alternative'. Good for them. It's not.

I'll put it this way; the issue you have requires a $10 solution, so why go looking for a $1000 solution?

It does not encrypt the .gnupg file, it encrypts the file within it. Try opening the .pdf file IN it. It will ask you for a password.

 

Unless you enable it, will never expire...

Why play crosswords when you can get straight to the point? The Riddler was never my favourite Batman character.

 

So basically then, are you saying that all this encryption is unnecessary and for the information that will be stored a simple Excel password will be perfectly fine?

 

That's one of the issues i'm having as i'm looking in to it more & more. Some people are responding like i should treat it as though i'd need to 'secure' my shopping list - so i could stick it in the local newspaper it doesn't really matter and the other end of the scale people seem to be saying i should treat it like the most confidential government file in history with security levels that don't even exist yet.

 

I'm not actually sure how secure it should be & that's the point.

 

The chances of someone wanting to get in to MY google drive out of all the google drives out there for information that wont even get them direct in to my accounts (no usernames/passwords will be stored) is slim. Obviously there's always a chance but it's slim, so to my mind a simple password from within Excel and from within Word SHOULD be fine, in theory.

 

But when people who i always consider more knowledgable than I anyway start talking about the need for encryption, it makes me wonder.

So would you equate this spreadsheet with a shopping list? If so, even applying a password is overkill.

 

You said you had a document that you want to edit while everyone else can just read. That solution was presented already on the first page.

 

What sort of data is on this spreadsheet? Usernames and passwords? Bank Accounts?

No, obviously i would not. The point i was making which i'm sure you got was that OTHERS are ranging from one extreme to the other and as this is my ball game i'm the one who needs to work out which road to go down. Obviously no protection whatsoever is a bad idea so it needs a MINIMUM of a password, but perhaps that's also the MAXIMUM it needs, i don't know.

Yes i do. I'm the one entering all this info. The family members are just there to read it. The last thing any of us wants (my mother would be the most likely culprit) is accidentally hitting a few cells, rewriting the info in there & saving it & not realising what they've done.

No, no usernames or passwords. They don't need that. Sure it'd be helpful but i don't want to get too technical with it. I want to keep it as simple as possible. I don't know how the American banking system works but i imagine somewhere similar to the UK one, so...

 

sort codes & account numbers.

Direct debits set up on each account - who the direct debit is paying, what it's for, an explanation of that payment if required, how much it is (if fixed amount) and how frequent it is.

Standing Orders on the account - who to (persons name), account it goes to, the amount it's for, why it's in place, how frequent it is.

Lists of current accounts (bank accounts), savings accounts including ISAs, brief pension account details including the banks/building societies/companies these are all with.

And a word document that will details for each person what they are to do in order to simplify everything - what needs to be cancelled etc so that it can run easily for them.

 

In the event i died they could go to each bank and say look, my son/brother/husband sorted out my money for me, these are the details i know about what i apparently hold with you and this is what he's instructed i do.

 

And each family member would have legal rights to do it all - because it'd all be in their own names, so they could prove ID without issue.

 

The average man would not be able to use any of that information to access the accounts and obtain the money inside because there are no usernames & passwords. Indeed, even beyond this i don't know how they'd access the money because while i'm monitoring it i'll notice anything that isn't right, like i did earlier in the year, and got in touch with the banks fraud department and had the money returned.

 

 

 

Sorry it's a bit long winded but if that helps you to help me then it's needed.

All I can say is don't use Excel for securing anything super important.  I've had many password protected spreadsheets that I've had to crack at work, and all it took was a 2 minute Google search for an Excel add-on that would crack the password.  It was actually kind of sad how easy it was.

Was that for Excel files from 2010 onwards? Because i read the Excel software from 2007 & previous was 'apparently' easy to hack.

I also saw a YouTube video today which apparently showed you how to hack sheets but all the replies were coming in saying if the actual file is passworded then the hack doesn't work.

It's about 17 years since i used Access on a Windows 3.1 or 3.11 machine or whatever it was. That long i can't even remember the version. I do remember needing some sort of programming knowledge but then that's what the teacher was for.

 

At the end of the day whatever is in place needs to be simple - both for me AND especially them.

 

My changes will be made whenever changes are made. It's taken me a week to put this together & i've not even finished yet because i find this part of it boring so i keep getting distracted. If i don't edit the whole thing as something changes then it'll get to the point where i have to do so much editing that i'll not want to bother, plus i'll forget so it needs to be done the moment anything changes.

 

I wonder about the .pdfs you mention and the secure site but at the same time i also do wonder about whether it makes things easier or not.

 

Now if a simple (ok not simply as in "password") password on the file is good enough then it can get thrown in to Google Drive which they can access no problem. That's only "IF" a password on the file is enough. Depends how easy they can be cracked.

It was on Excel 2016. The add-on would decrypt and even display the password.

I've since moved to Office 365 and haven't retried the add-on, so I'm not sure if it still works.

Well there is excelsafe.  Probably the only way to really secure the file.

Excel shouldn't really be used though.  If you are trying to secure excel you should be considering sql and building an app to support your needs/ui.

No offence but you're talking a totally foreign language to me now and this could fast start getting way away from me. Nothing against what you're saying but my understanding can't keep up with you.

 

I'll have to look at the encryption side of things.

"sql"s and "building apps". I'm no app creator, i wouldn't even know where to begin. What i'm saying is i think it's beyond my capabilities. Maybe it isn't but at the moment with the understanding i have, it is.

 

I'm in the process of going ahead with the Excel file as it's what i know. Not to say it can't change at a later date if i can extract the info without manually entering it all again but i need something in place this week as i'm off work. Once i'm back at work i guarantee 100% i wont feel like doing it so it needs to be done now.

What i'm looking for is something simple. Nothing too technical. If i don't need encryption then i don't need it, if i do then i do. If Google Drive is ok then it's ok, if it's not then i need an alternative.

 

It's ok certain members here getting all huffy because i "don't listen" to THEM. Thing is i do, but i also have people on the internet disagreeing with each other. Google Drive is no good, Google Drive is fine. Encryption is overkill, Encryption is required. The password from within Excel is fine enough, the password from within Excel can get cracked in 5 seconds flat. That only applies to older Excel versions, no it doesn't it applies to newer ones also.

 

And if i don't do what 'one' of them says then i'm "not listening" and i was "told on page x".

 

I'm the one that needs to determine A) which suggestion i think i can understand because i'm not a huge techy guy and B) which i think is suitable, because everyone is here saying they know better than the man on their right.

redacted everything.....

 

 

 

Edit: Yea, this is way above your needs.  And you are way overcomplicating things.  Just make a file and put it on google drive or onedrive or box or dropbox.  Zip it up and password protect it with a password you all know.  damn man...use lastpass and document there.  give everyone in your family the password for lastpass and document there.

When did we ever disagree with each other? That was you asking 100 questions and not understanding us.

I went on YouTube to see about this gpnub thing or whatever it is. See how to use it. No wonder it baffled the F out of me.

They were showing you having to do coding. I've never done coding just like i never do foreign languages! Only language i do is English.

 

So then i had a look on YouTube at that VeraCrypt and how you use it. Made it look quite easy to understand.

Creating a file which operates like a hard drive (or so it seems to my eyes) that is encrypted.

I saw how to make a USB flash drive encrypted. My only wondering then though is that could you put the VeraCrypt installer on the USB stick (i'm guessing not) because the chances of anyone remembering what program they need to install to open the files on there would be a bit slim.

UNLESS you could partition the USB stick, which i've never actually done.

But yeah, VeraCrypt looked much easier to understand.

 

So your google fu is just as bad as the rest of your tech skills it seems.

 

Did you think of just RTFM?

https://www.gpg4win.org/doc/en/gpg4win-compendium_24.html

Signing and encrypting files

 

So now your going to partition USB sticks.. Vs just right clicking a file and picking encrypt or decrypt?  Because you did a google and saw someone use a cmd line?

 

How exactly are you going to update these remote USB sticks with an encrypted partition on them?  Vs storing a file in the cloud that these people have access to.. Or just emailing them a new copy.. Or having them sync the new copy to their machines via dropbox, or any of the other sync packages..

 

To be honest the lastpass emergency access is going to be the EASY no Brianer way for you to do this... And is FREE you do not have to use premium..  No "coding" involved... 

 

Other then you read some idiot on the net telling you not to store stuff online...

 

Was it this guy?

If i knew what RTFM was then i'd answer you. That's the problem when tech guys use abbreviations on non-tech guys.

Makes them feel good inside because they know something someone else doesn't - or at least this statement applies for certain types.

Once again you jump the gun. As much as i may not get what you say or at least not immediately, you sure do like to jump the gun.

LOOKING AT partitioning USB sticks was one possibility. I had a look that Windows only 'sees' or lets you use the first partition so that's that option out of the window. That's the thing - i look at possibilities and decide from there whether +/-.

And yeah i "did a google" or rather i used YouTube, because i have on one side someone saying "this is easy, just do it". Niiiiiiiiiiice. So i went looking to find someone to show me how to do it (YouTube) and saw command lines and that's when i said you know what - typical of this guy. He's aware of my limitations (remember from before - car shiny, car go fast?) so he's suggested something more technical than a suitable other option because he knows what's going to happen when i try it.

Like i said, USB has been put aside now, it's not really an option.

 

 

 

Is there a reason you appear to be against VeraCrypt for example? I know you haven't word-for-word said you're not but you're saying encrypt the file and as far as i can see that's what VeraCrypt does, it's just a different program. I can get from A-B in a Ford just like i can get from A-B in a Nissan. I'm still getting from A-B.

If i have to do this first

Then i got as far as name and email address. It then asks me whether i want to back it up or not and regardless of whether i say yes or no, it returns an invalid argument error and the program crashes.

Dude how is you have found neowin back in 2003.. And have never seen RTFM? 

 

Is ROFL, or LOL unknown to you as well?

 

Here is a clue when you see an acronym how about you freaking google, or hey alexa what does RTFM mean ;)

 

Back in my day before the internet teacher would hand you the dictionary when there was a word you didn't understand.. It's the same thing - is this freaking 2nd grade?

 

Literally it would take you less time to look up that acryonm then post your response.  I mean really.. Its like you like to come to a tech site and play like this is your first day with a freaking computer..  The more I read your stuff the more I think your just freaking trolling..  Do you not know what trolling means?  Here let me google that for you ;)

    • Windows 11 KB5062233/ KB5060843/ KB5062197/ KB5061090 setup, recovery updates released by Sayan Sen This week Microsoft released non-security preview updates for Windows 11 22H2 and 23H2 under KB5060826 as well as for 24H2 under KB5060829. The company also published dynamic updates alongside them. Dynamic updates bring improvements to the Windows Recovery in the form of Windows Recovery Environment (WinRE) updates, also called Safe OS updates, as well as to the Setup binaries in the form of Setup updates. These Dynamic Update packages are meant to be applied to existing Windows images prior to their deployment. These packages include fixes to Setup.exe binaries, SafeOS updates for Windows Recovery Environment, and more. Dynamic Updates also help preserve Language Pack (LP) and Features on Demand (FODs) content during the upgrade process. VBScript, for example, is currently an FOD on Windows 11 24H2. Both setup and recovery updates were released. The changelogs are given below. First up we have the Setup updates: Up next, we have the recovery updates: Microsoft notes that the Recovery updates will be downloaded and installed automatically via the Windows Update channel. The Setup updates, however, need to be downloaded and installed manually. You can avail them on Microsoft's Update Catalog website: KB5062233, KB5060843, KB5062197, and KB5061090.
    • Gaming mouse review: Keychron Lemokey G2 8K Wireless, high performance, light in weight by Robbie Khan Available in the UK and USA, the G2 is a wireless gaming mouse by Lemokey, the customised gaming peripheral arm of Keychron, a brand many readers will know well. I've checked out Keychron keyboards recently, models such as the top-tier Q6 Max, and the bargain priced B6 Pro. I never got the chance to check out the G1, but the G2 seems to put itself firmly in-between competing 8K gaming mice out there whilst coming in at a decent sum under £100/$100. The other benefit is that it uses Keychron Launcher, the web-based software that has been a staple part of Keychron keyboards for a long time now. I rate the launcher highly and have rarely had a problem with it, so it is great to see a robust piece of software being used on an affordable gaming mouse that's not only built well, but performs well, too. As it's a high performance gaming mouse with a flagship PixArt sensor, I will be comparing the G2 directly against my personal mouse, the similarly sized Pulsar Feinmann F01. Both mice are priced wildly differently, so it was interesting to compared several factors between them to see if one bests the other where it matters most, or if it just comes down to individual preferences. Let's check out the specs... Keychron Lemokey G2 SKU G2-A1 Sensor PixArt 3950 IPS 750 MCU Realtek 8762G Connectivity Bluetooth 5.1 / 2.4 GHz / Wired (type-C cable) Polling Rate Up to 8000 Hz (2.4 GHz / wired mode), 125 Hz (Bluetooth mode) Motion Sync Yes Angle Snapping Yes Acceleration 50g Cable Detachable Type-C to C Cable + Type-A to Type-C adapter Dongle Micro USB-A dongle Main switches Huano Micro Switch Switch lifespan 80 Million Clicks Battery 300 mAh Battery life 60 Hours (Under 1000Hz) 35 Hours (1000-4000Hz) 20 Hours (4000-8000Hz) Skates Teflon / PTFE Lift Off Distance 0.7 / 1.0 / 2.0 mm Material (Body and Grip) ABS Dimensions 118mm / 62.6mm / 38.2mm Tracks on glass (min. 4 mm thickness) Yes (max 1000Hz report rate) Weight 52 ± 3 g Colours Black / White Price £73.99 / $69.99 Fit and finish Made of all ABS, it certainly doesn't feel anywhere near as nice as the F01, but then again it's priced much lower, so no complaints there. To me it feels more like a previous generation Endgame/Zowie mouse, before they started to use the more grippy textured finish. It's a fine finish but how long that lasts only time will tell. With the Endgame mice I always found that the side buttons would go shiny first, and I suspect the exact same to apply here with the G2, since the size and shape of them is similar, as is the material quality. Speaking of side buttons, my personal preference is flat and large buttons, the long and pointed ones like those on the G2 shown above and GAMIAC PX71 at the bottom always felt a bit awkward to me for naturally resting a thumb on, whereas the large surface area of the ones found on the Feinmann and others like it feel more ergonomic and comfortable for long usage sessions. Pulsar Feinmann F01 (ergo shape) Lemokey G2 (ambidextrous shape) Under my 19cm hand, the G2 feels comfortable and stable for both claw and palm grip styles, though my usual style is a hybrid approach. I like to pinch a mouse with a thumb and ring finger, then articulate forward or backward movement with them to adapt to different play-styles. Both mice have a sloping back hump that works brilliantly for this and i had no problem getting comfortable with the G2 here. The underside of the G2 hides a cool feature I wish more more mice makers adopted, can you spot what it is in the photo below? That little flap at the bottom to store the USB dongle, it's convenient, especially for gamers who travel with their mice or laptop gamers. The skates applied are PTFE and cover three zones on the underside, sadly I forgot to take a photo of them before swapping them out to my preferred skates, the Wallhack Pro UWMP yellow dots. I found no problem with glide resistance on the stock skates, though find dots glide nicer overall and these yellow dots slide around like butter. Lemokey states 52g for the weight, give or take 3g, so my scales measure up perfectly here. It's not as lightweight as the Feinmann which currently is 45g, but it's still considered super-light and honestly, under the hand, this weight difference on dot skates is hard to tell apart. Gripping the G2 hard on both sides shows no obvious issues with flexing, so the internal construction is also up to scratch and exactly what i would expect in this price range. The differences start to be noticed when you are using the G2 as a combination mouse, both in gaming and desktop use. The wheel is thinner than the one on the Feinmann and other gaming mice with fat wheels. I much prefer a nice wide wheel, the diameter is also much larger as can be seen with the overhead photo above. The button tops also have a distinct difference in feel when actuating the switches. there is more of a hollow feel to the G2's tops, as well as slightly more travel post-click. the Huano switches feel and sound excellent, though, but I think the ABS contact surface on the outside could have been slightly more distinct in feel. Here is a demo of how the main switches sound, you can also hear the switch tops clap if you pay attention: Likewise the side buttons have extra play after the switches actuate, something the Feinmann and others in the higher price category don't tend to have. Features & software Aside from the usual features that all gaming mice support these days, such as Motion Sync, lift off distance and Macro, the big feature with the G2 is that is uses Keychron Launcher, the web-browser based software. All changes are stored directly onto the on-board memory, here is what the sections within it look like: I found no bugs with the implementation here, and unlike other Keychron wireless devices I have used with Launcher in the past, the G2 connects and can be customised in it over both wired and wireless. Just be aware that the firmware update option when connected via wireless will only check the dongle's firmware. To check the G2's firmware, a USB cable will need to be connected. Performance Whether on the desktop in Windows or in games, the cursor and motion performance is excellent, though this is to be expected from all modern gaming mice, regardless of price. The higher priced mice tend to have better use of high quality materials, and implementation of software and physical features. I'm currently pacing through nine games, all mixed genre, and in each of them I had no troubles quickly getting comfortable with the G2. If you're used to an Endgame XM2we sized mouse, then this will be just as familiar to you. The convenience of the DPI button at the top of the mouse instead of underside makes instant switching simpler, although the button can be remapped to do something else for those who don't care about DPI toggling. Here is a demo of the G2 playing Doom: The Dark Ages: The sensor tracking performance at 8K was perfect, aside from the few moments my physical movement on the mousepad slowed down causing some drops in the Razer mouse tracking measurement graph below: A consistent 7900-8000Hz polling was observed, though keep in mind that using such high polling rates will impact CPU performance whilst gaming. How much this affects framerates will boil down to the CPU you have. On my i7 12700KF there was no change whilst gaming, but during the measurement above I did observe 13% CPU package utilisation. In practice, though, I saw no performance difference playing at 8K versus 2K or even 1K. Battery life will drastically be impacted at 8K polling rates for obvious reasons, and whilst many prefer 4K, there is a growing trend to just stick to 2K which feels the safe middle ground of great battery performance, whilst still being suitably responsive on paper for even the most fast-paced of gaming sessions. Conclusion The Lemokey G2 has proven to be a rather excellent mouse, not just for gaming, but general use, too. Though being excellent doesn't give it any special status, as there are equally excellent mice out there that cost the same, less and even more. A buying decision will come down to individual needs, do you value the use of a browser-based software tool like Keychron Launcher? If so, then this is right up your street. Do you want something lightweight but also supports the gaming features and feel in the hand as more expensive mice? Maybe the G2 will satisfy. It's not totally perfect, nothing ever is, the thumb buttons could have been a bit wider, and the switch caps have more travel after clicking than what I am comfortable with, but otherwise this is a great mouse with features that rival the competition. The sensors on gaming mice these days isn't a key selling factor any more either, since even entry level gaming mice are capable of precision tracking and speed that was only possible on the top-tier models of the past, like many things in tech now, the point of diminishing returns has been reached, and brands have to work harder at giving us consumers a unique selling point to attract interest. I believe the G2 has at least one USP (Keychron Launcher), it also helps that it's a very comfortable mouse to use for all-day sessions.
