Struct Fp2

Source 
pub struct Fp2(/* private fields */);
Expand description

Fp2 represents an element of the quadratic extension field Fq2 of the BLS12-381 elliptic curve

§Serialization:

  • The 96 bytes represent the big-endian encoding of an element in the field Fp2. The bytes consist of be_bytes(c1) || be_bytes(c0) (|| is concatenation), where c0 and c1 are the two Fp elements (the real and imaginary components).
