MD5 is a hash that's normally displayed as a 32 character string. That
means that even the MD5 hash of a 2GB files is 32 byte long: if it was
reversable we would have found the most amazing compression algorithm ;-)
Encryption can be rather complicate. I suggest you first define your needs
and then find solutions for them.
Hashes have several usages:
* Test file integrity
* Password storage (you cannot decrypt passwords, yet you can encrypt the
value provided by user and compare)
