Skein-256
Skein-256
SHA-3 finalist (Skein v1.3, 2010) by Schneier et al. Built on Threefish-256 via UBI (Unique Block Iteration) chaining — a Davies-Meyer construction. Pipeline: Config → Message → Output. Each block encrypted with Threefish-256 then XORed with plaintext. 256-bit output.

Russian national hash function (GOST R 34.11-2012, RFC 6986). 512-bit internal state processed through 12 rounds of a Kuznyechik-family SPN in a Miyaguchi-Preneel-like compression function, with a unique checksum-based finalization step.
Secure Hash Algorithm 2. Produces a unique 256-bit hash output representing the input message.
Secure Hash Algorithm 2 with 64-bit words, producing a secure 512-bit digest.
