BCrypt based key derivation function to improve BCrypt as a cryptographic primitive for password hashing and key derivation

Implementation of the single-step key derivation function (KDF) as described in NIST Special Publication 800-56C Rev1 supporting messages digest and HMAC.

A Java standalone implementation of the bcrypt password hash function. Based on the Blowfish cipher it is the default password hash algorithm for OpenBSD and other systems including some Linux distributions. Includes a CLI Tool.

Bytes is a utility library that makes it easy to create, parse, transform, validate and convert byte arrays in Java. It supports endianness as well as immutability and mutability, so the caller may decide to favor performance.

A standalone Java 7 implementation of HMAC-based key derivation function (HKDF) defined in RFC 5869 first described by Hugo Krawczyk. HKDF follows the “extract-then-expand” paradigm which is compatible to NIST 800-56C Rev. 1 two step KDF

A cryptographically secure pseudorandom number generator cli tool printing in a wide variety of byte encodings (hex, base64,..) and for many programming languages (c, java, c#, php, etc.) using NIST SP800-90Ar1 HMAC-DRBG. Supports external seeding from various true random services.
