NIST curve secp256r1

NIST curve secp384r1

NIST curve secp521r1

a: Curve equation coefficient See https://www.secg.org/sec2-v2.pdf

b: Curve equation coefficient See https://www.secg.org/sec2-v2.pdf

h: Cofactor of the cyclic subgroup generated by G See https://www.secg.org/sec2-v2.pdf

the number of bits/bytes needed to store point coordinates (such as public key coordinates) in unsigned form

the number of bytes needed to store a public key coordinate in unsigned form

Returns a representation of an immutable list of all enum entries, in the order they're declared.

G: Generator of cyclic curve subgroup See https://www.secg.org/sec2-v2.pdf

Returns the length of a private key, when it is exported from iOS. This is handy, because Apple does not encode curve identifiers, but implies them based on the length of the key

Returns the length of a public key, when it is exported from iOS. This is handy, because Apple does not encode curve identifiers, but implies them based on the length of the key

the number of bits needed to store a private key in unsigned form

p: Prime modulus of the underlying prime field See https://www.secg.org/sec2-v2.pdf

A digest well-suited to operations on this curve, with output length near the curve's coordinate length.

r: Order of (the cyclic subgroup generated by) G See https://www.secg.org/sec2-v2.pdf

the number of bits/bytes needed to store scalar multipliers (such as private keys) in unsigned form

the number of bytes needed to store a raw signature (r and s concatenated) over this curve

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Returns an array containing the constants of this enum type, in the order they're declared.
