| Method Detail |
public int getFormatID()
IKeyPairCodecReturns the unique identifier (within this library) of the format used to externalise public and private keys.
getFormatID in interface IKeyPairCodecpublic byte[] encodePublicKey(java.security.PublicKey key)
Returns the encoded form of the designated SRP public key according to the Raw format supported by this library.
The Raw format for an SRP public key, in this implementation, is a byte sequence consisting of the following:
Registry.MAGIC_RAW_SRP_PUBLIC_KEY,N in internet order,BigInteger obtained by invoking
the toByteArray() method on the SRP parameter
N,g,BigInteger obtained by invoking
the toByteArray() method on the SRP parameter
g,y,BigInteger obtained by invoking
the toByteArray() method on the SRP parameter
y,
encodePublicKey in interface IKeyPairCodeckey - the key to encode.
java.lang.IllegalArgumentException - if the designated key is not an SRP one.public java.security.PublicKey decodePublicKey(byte[] k)
IKeyPairCodecDecodes an instance of an external public key into its native Java representation.
decodePublicKey in interface IKeyPairCodeck - the source of the externalised key to decode.
public byte[] encodePrivateKey(java.security.PrivateKey key)
Returns the encoded form of the designated SRP private key according to the Raw format supported by this library.
The Raw format for an SRP private key, in this implementation, is a byte sequence consisting of the following:

is included in this encoding (value 0x01) or not
