Just be warned: there are different ways of formatting that result, and it
assumes no salt. Best practices for authentication are to prepend a
per-user salt before creating each hash value. And really, best practices
say not to use md5 for passwords at all. It's too weak, almost to the point
where you may just as well store your passwords in plain text. A better
option is bcrypt, which is now supported by koha.

hashes are not encryption. The difference between a hash and encryption is
that hashes are* one way*: *they cannot be decrypted/decoded*.
