Bcrypt for Delphi

Bcrypt is an algorithm designed for hashing passwords, and only passwords; i.e., it's:

• not a high-speed, generic hashing algorithm;
• computationally and memory expensive;
• limited to passwords of 55 bytes.

It uses the Blowfish encryption algorithm, but with an "expensive key setup" modification, contained in the function EksBlowfishSetup.
