[Gambas-user] Crypt/Decrypt

[nando]

MD5 isn't used to decrypt.
It's used to encrypt...one way only.
For security and passwords: ** Do NOT ** compare decrypted secrets.
Always compare encrypted secrets.
When you make databases with passwords, you do not want to know
passwords...store them encrypted and process with them encrypted.
When passwords are forgotten, reset them to something.
