Computable implementation for the Galois Field 128-bit

Stream: Is there code for X?

[Chung Thai Nguyen]

Hi everyone, is there an open-sourced implementation of computable Galois Field GF(2^128), proposed in the NIST SP 800-38D standard for AES-GCM (Galois/Counter Mode). The field is defined by defined by the irreducible polynomial $P(x) = x^{128} + x^7 + x^2 + x + 1$ over GF(2).
Thanks.
