WebApr 4, 2024 · NewGCM returns the given 128-bit, block cipher wrapped in Galois Counter Mode with the standard nonce length. In general, the GHASH operation performed by this implementation of GCM is not constant-time. An exception is when the underlying Block was created by aes.NewCipher on systems with hardware support for AES. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.

However, that would require implementing POLYVAL on top of GHASH, which, while technically possible, is somewhat awkward and inefficient due different byte orders used by the two hashes.
