WebBecause every finite field of a given size is equivalent, any field with 256 elements always has the same universal properties. Galois, who died at age 20 in the chaos of post-Napoleon France, blazed the mathematical trail to much of this area, so we call the field with 256 elements GF(2 8), or "Galois Field with 2 8 elements". WebDec 6, 2024 · Since -1 is the same as 1 in binary arithmetic, BN_GF2m_sub() does exactly the same as BN_GF2m_add(). It is implemented as a macro. BN_GF2m_cmp() is an alias for BN_ucmp(3).
