Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linuxPull crypto library updates from Eric Biggers: - Add support for verifying ML-DSA signatures. ML-DSA (Module-Lattice-Based Digital Signature Algorithm) is a recently-standardized post-quantum (quantum-resistant) signature algorithm. It was known as Dilithium pre-standardization. The first use case in the kernel will be module signing. But there are also other users of RSA and ECDSA signatures in the kernel that might want to upgrade to ML-DSA eventually. - Improve the AES library: - Make the AES key expansion and single block encryption and decryption functions use the architecture-optimized AES code. Enable these optimizations by default. - Support preparing an AES key for encryption-only, using about half as much memory as a bidirectional key. - Replace the existing two generic implementations of AES with a single one. - Simplify how Adiantum message hashing is implemented. Remove the "nhpoly1305" crypto_shash in favor of direct lib/crypto/ support for NH hashing, and enable optimizations by default.* tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (53 commits) lib/crypto: mldsa: Clarify the documentation for mldsa_verify() slightly lib/crypto: aes: Drop 'volatile' from aes_sbox and aes_inv_sbox lib/crypto: aes: Remove old AES en/decryption functions lib/crypto: aesgcm: Use new AES library API lib/crypto: aescfb: Use new AES library API crypto: omap - Use new AES library API crypto: inside-secure - Use new AES library API crypto: drbg - Use new AES library API crypto: crypto4xx - Use new AES library API crypto: chelsio - Use new AES library API crypto: ccp - Use new AES library API crypto: x86/aes-gcm - Use new AES library API crypto: arm64/ghash - Use new AES library API crypto: arm/ghash - Use new AES library API staging: rtl8723bs: core: Use new AES library API net: phy: mscc: macsec: Use new AES library API chelsio: Use new AES library API Bluetooth: SMP: Use new AES library API crypto: x86/aes - Remove the superseded AES-NI crypto_cipher lib/crypto: x86/aes: Add AES-NI optimization ...

14e15c71d7bb591fd08f527669717694810d3973 - lib/crypto: nh: Add NH library

Thu, 11 Dec 2025 01:18:33 +0000

lib/crypto: nh: Add NH libraryAdd support for the NH "almost-universal hash function" to lib/crypto/,specifically the variant of NH used in Adiantum.This will replace the need for the "nhpoly1305" crypto_shash algorithm.All the implementations of "nhpoly1305" use architecture-optimized codeonly for the NH stage; they just use the generic C Poly1305 code for thePoly1305 stage. We can achieve the same result in a simpler way usingan (architecture-optimized) nh() function combined with code incrypto/adiantum.c that passes the results to the Poly1305 library.This commit begins this cleanup by adding the nh() function. The codeis derived from crypto/nhpoly1305.c and include/crypto/nhpoly1305.h.Link: https://lore.kernel.org/r/20251211011846.8179-2-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/nh.c
