hkdf

✅ .NET crypto done right. Professionally audited.

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.

A modern and easy-to-use cryptographic library for .NET Core based on libsodium

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

🔐 Fastest crypto library for Deno written in pure Typescript. AES, Blowfish, CAST5, DES, 3DES, HMAC, HKDF, PBKDF2

IDMask is a Java library for masking internal ids (e.g. from your DB) when they need to be published to hide their actual value and to prevent forging. It has support optional randomisation has a wide support for various Java types including long, UUID and BigInteger. This library bases its security on strong cryptographic primitives.
