Having had serious problems with other backup/file-archiving methods, I now use the USAF Encryption Wizard (now called TENS, nothing to do with relief from pain) to encrypt-archive some crucial work files.
My procedure is to encrypt-archive the crucial files with the USAF Encryption Wizard and then I decrypt-expand the .wza file that the USAF Encryption Wizard has created to another folder. I then use QuickHash to check that the decrypted-expanded files are identical to the originals. Since there are over 180MB of crucial files, I cannot manually check each file, even though the USAF Encryption Wizard does support hashing files.
Without QuickHash I would be unable to use the method I currently use. The encrypted archive is uploaded to Dropbox, which does not support user-supplied encryption keys.
I have spot-checked the accuracy of what QuickHash is doing by using the USAF Encryption Wizard’s hashing function on some files. I did those spot-checks on an earlier version of QuickHash and will in due course do the same spot-check on the current version.
