README

        
jBCrypt 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.

JUnit regression tests are available in in TestBCrypt.java

jBCrypt is licensed under a ISC/BSD licence. See the LICENSE file for details.

Please report bugs to Damien Miller . Please check the

TODO file first, in case your problem is something I already know about

(please send patches!)

A simple example that demonstrates most of the features:

	// Hash a password for the first time

	String hashed = BCrypt.hashpw(password, BCrypt.gensalt());

	// gensalt's log_rounds parameter determines the complexity

	// the work factor is 2**log_rounds, and the default is 10

	String hashed = BCrypt.hashpw(password, BCrypt.gensalt(12));

	// Check that an unencrypted password matches one that has

	// previously been hashed

	if (BCrypt.checkpw(candidate, hashed))

		System.out.println("It matches");

	else

		System.out.println("It does not match");

There is also a C#/.NET port by Derek Slager:
