csBCrypt is an implementation the OpenBSD Blowfish password hashing algorithm, as described in "A Future-Adaptable Password Scheme" by Niels Provos and David Mazieres: http://www.openbsd.org/papers/bcrypt-paper.ps

This system hashes passwords using a version of Bruce Schneier's Blowfish block cipher with modifications designed to raise the cost of off-line password cracking. The computation cost of the algorithm is parameterised, so it can be increased as computers get faster.

NUnit regression tests are available in TestBCrypt.cs

A simple example that demonstrates most of the features:

// Hash a password for the first time
string hashed = BCrypt.CreateHash(password, BCrypt.GenerateSalt());

// GenerateSalt's log_rounds parameter determines the complexity
// the work factor is 2**log_rounds, and the default is 10
string hashed = BCrypt.CreateHash(password, BCrypt.GenerateSalt(12));

// Check that an unencrypted password matches one that has
// previously been hashed
if (BCrypt.VerifyPlaintext(candidate, hashed))
	Console.WriteLine("It matches");
else
	Console.WriteLine("It does not match");

This repository is based off of version 0.4 of jBCrypt found here: http://www.mindrot.org/projects/jBCrypt/

I have also mirrored all versions of jBCrypt on a personal repository found here: https://github.com/chriswebb/jBCrypt/

BCrypt.Net is based off of the same repository, but was not used in the making of this port. So this is not a fork of BCrypt.Net. This is a standalone port of jBCrypt.
