The Streebog Algorithm

Streebog, or GOST R 34.11-2012, is the Russian hash function standard. It hashes with a 12-round AES-like cipher, a length counter, and a checksum. Learn how its S-box, byte transposition, and linear map work, with every round of the RFC 6986 example checked.

The Whirlpool Algorithm

Whirlpool is a 512-bit hash function built from an AES-like block cipher that works on an 8 by 8 matrix of bytes. Learn how its S-box, column shift, and diffusion matrix work, how the Miyaguchi-Preneel mode turns the cipher into a hash, and how it compares with SHA-2.
