+
+[GHASH][1] is a [universal hash function][2] which operates over GF(2^128) and
+can be used for constructing a [Message Authentication Code (MAC)][3].
+
+Its primary intended use is for implementing [AES-GCM][4].
+
+[Documentation][docs-link]
+
+## Security Notes
+
+This crate has received one [security audit by NCC Group][5], with no significant
+findings. We would like to thank [MobileCoin][6] 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).
+

+//! **GHASH**: universal hash over GF(2^128) used by AES-GCM for message
+//! authentication (i.e. GMAC).
+//!
+//! ## Implementation Notes
+//!
+//! The implementation of GHASH found in this crate internally uses the
+//! [`polyval`] crate, which provides a similar universal hash function used by
+//! AES-GCM-SIV (RFC 8452).
+//!
+//! By implementing GHASH in terms of POLYVAL, the two universal hash functions
+//! can share a common core, meaning any optimization work (e.g. CPU-specific
+//! SIMD implementations) which happens upstream in the `polyval` crate
+//! benefits GHASH as well.
+//!
+//! From RFC 8452 Appendix A:
+//! <https://tools.ietf.org/html/rfc8452#appendix-A>
+//!
+//! > GHASH and POLYVAL both operate in GF(2^128), although with different
+//! > irreducible polynomials: POLYVAL works modulo x^128 + x^127 + x^126 +
+//! > x^121 + 1 and GHASH works modulo x^128 + x^7 + x^2 + x + 1. Note
+//! > that these irreducible polynomials are the "reverse" of each other.
