net.i2p.crypto.SigType
public enum SigType
Defines the properties for various signature types that I2P supports or may someday support. All Signatures, SigningPublicKeys, and SigningPrivateKeys have a type. Note that a SigType specifies both an algorithm and parameters, so that we may change primes or curves for a given algorithm.
