Recently I have to deal with cryptography more and more often, usually in form of protection of files against reading and modification, but also digital signatures.

comment How to represent a 32-byte SHA2 hash in the shortest possible string?
Why use it as a directory prefix? Directories and files could be renamed by the user. An option might be Alternate Data Streams (if NTFS) so you can store the hash invisible as part of the file itself. However, it will be lost when copied from NTFS to some other file system.
