Software for transferring/sync files with server and offering data val

[lsquare]

I know this may be a bit paranoid, but I'm just wondering if there are any freewares for transferring or synchronizing files with my home server and at the same time output SHA-1 or MD-5 hashes? The reason why I need something like this is to ensure data integrity. Some of these files are very important to me and I need a way to ensure that no file corruption had occurred during the transferring process.
