RustCrypto: GF(2^128) "dbl" operation

crate Docs Build Status Apache2/MIT licensed Rust Version Project Chat

Double operation in Galois Field GF(2^128) as used by e.g. CMAC/PMAC.

Also known as "multiply-by-x", the operation is performed in the finite field represented using the primitive polynomial x^128 + x^7 + x^2 + x + 1.
