org.jose4j.keys.EllipticCurves

public class EllipticCurves
extends Object

Values for these (the NIST P-*) curve parameters taken from FIPS PUB 186-3 and http://www.nsa.gov/ia/_files/nist-routines.pdf The secp256k1 curve parameters came from inspecting the params on a key pair generated with ECGenParameterSpec("secp256k1")
