> The base field is the set of numbers modulo a large prime number (such as 2^255-19, from which Curve25519 takes its name). The implementation provides arithmetic operations in the field, such as modular addition, subtraction, multiplication, and inversion, as well as encoding and decoding of field elements to/from bytes.
