Digital security for all, everywhere, no matter who they are, or what they believe in.
This is a 100% Kotlin Multiplatform implementation of SHA-3. It does not depend on any third-party library.
This is used in KyberKotlin, an ML-KEM implemention of NIST FIPS 203.
- SHA3-224
- SHA3-256
- SHA3-384
- SHA3-512
- RawSHAKE128 (Extendable, Byte Stream-able)
- RawSHAKE256 (Extendable, Byte Stream-able)
- SHAKE128 (Extendable, Byte Stream-able)
- SHAKE256 (Extendable, Byte Stream-able)
- JVM (Kotlin, Java)
- JS (Node, Bun)
