RustCrypto: GHASH
GHASH is a universal hash function which operates over GF(2^128) and can be used for constructing a Message Authentication Code (MAC).
Its primary intended use is for implementing AES-GCM.
Security Notes
This crate has received one security audit by NCC Group, with no significant findings. We would like to thank MobileCoin for funding the audit.
All implementations contained in the crate are designed to execute in constant time, either by relying on hardware intrinsics (i.e. AVX2 on x86/x86_64), or using a portable implementation which is only constant time on processors which implement constant-time multiplication.
It is not suitable for use on processors with a variable-time multiplication operation (e.g. short circuit on multiply-by-zero / multiply-by-one, such as certain 32-bit PowerPC CPUs and some non-ARM microcontrollers).
