Adiantum (cipher): Standards & Overview

Adiantum is a cipher composition for disk encryption. It uses a new cipher construction called HBSH (hash, block cipher, stream cipher, hash), specifically choosing NH, 256-bit Advanced Encryption Standard (AES-256), (X)ChaCha12/ChaCha20, Poly1305 for the four elements. The version in Linux kernel preferentially uses XChaCha12, xchacha12,aes-adiantum.
