decodePrivateKey
public PrivateKey decodePrivateKey(byte[] k)
Decodes an instance of an external private key into its native Java
representation.
- decodePrivateKey in interface IKeyPairCodec
- a concrete instance of a private key, reconstructed from the
designated input.
IllegalArgumentException - if the designated input does not
contain a known representation of a private key for the format
supported by the concrete codec.
decodePublicKey
public PublicKey decodePublicKey(byte[] k)
Decodes an instance of an external public key into its native Java
representation.
- decodePublicKey in interface IKeyPairCodec
- a concrete instance of a public key, reconstructed from the
designated input.
IllegalArgumentException - if the designated input does not
contain a known representation of a public key for the format
supported by the concrete codec.
encodePrivateKey
public byte[] encodePrivateKey(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:
- 4-byte magic consisting of the value of the literal
Registry.MAGIC_RAW_SRP_PRIVATE_KEY, - 1-byte version consisting of the constant: 0x01,
- 4-byte count of following bytes representing the SRP parameter
N in internet order, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter N,
- 4-byte count of following bytes representing the SRP parameter
g, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter g,
- 4-byte count of following bytes representing the SRP parameter
x, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter x,
- one byte which indicates whether the SRP parameter
v is
included in this encoding (value 0x01) or not (value
0x00). - 4-byte count of following bytes representing the SRP parameter
v, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter v,
- encodePrivateKey in interface IKeyPairCodec
- the Raw format encoding of the designated key.
encodePublicKey
public byte[] encodePublicKey(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:
- 4-byte magic consisting of the value of the literal
Registry.MAGIC_RAW_SRP_PUBLIC_KEY, - 1-byte version consisting of the constant: 0x01,
- 4-byte count of following bytes representing the SRP parameter
N in internet order, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter N,
- 4-byte count of following bytes representing the SRP parameter
g, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter g,
- 4-byte count of following bytes representing the SRP parameter
y, - n-bytes representation of a
BigInteger obtained by invoking
the toByteArray() method on the SRP parameter y,
- encodePublicKey in interface IKeyPairCodec
- the Raw format encoding of the designated key.
getFormatID
public int getFormatID()
Returns the unique identifier (within this library) of the format used to
externalise public and private keys.
- getFormatID in interface IKeyPairCodec
- the identifier of the format, the object supports.
