bkdf

GitHub · · Java · 2 · v0.6.0
BCrypt based key derivation function to improve BCrypt as a cryptographic primitive for password hashing and key derivation

singlestep-kdf

GitHub · · Java · 8 · v0.3.0
Implementation of the single-step key derivation function (KDF) as described in NIST Special Publication 800-56C Rev1 supporting messages digest and HMAC.

armadillo

GitHub · · Java · 272 · v1.0.0
A shared preference implementation for confidential data in Android. Per default uses AES-GCM, BCrypt and HKDF as cryptographic primitives. Uses the concept of device fingerprinting combined with optional user provided passwords and strong password hashes.

hkdf

GitHub · · Java · 59 · v2.0.0
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
