✅ .NET crypto done right. Professionally audited.

Usable, easy and safe pure-Rust crypto

Audited & minimal JS implementation of hash functions, MACs and KDFs.

A modern and easy-to-use cryptographic library for .NET 6+ based on libsodium

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 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

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.
