A encryption/decryption library using bitwise xor
xor_cryptor, but with a minimum key length of 1
Constant-time-designed pure-Rust SM2/SM3/SM4 primitives (no_std + alloc) with an in-CI dudect timing-leak regression harness
SIMD backends for gmcrypto-core — AVX2 (x86_64) and NEON (aarch64) packed bitsliced SM4 S-box, quarantined to keep `gmcrypto-core` `unsafe_code = forbid`
