Method Detail

toByteArray

public byte[] toByteArray()
                   throws KeyAgreementException

Returns the encoded form of the current message including the 4-byte length header.

Throws:

KeyAgreementException - if an encoding size constraint is violated.

wrap

public byte[] wrap()
            throws KeyAgreementException

Returns the encoded form of the current message excluding the 4-byte length header.

Throws:

KeyAgreementException - if an encoding size constraint is violated.

writePublicKey

public void writePublicKey(java.security.PublicKey k)
                    throws KeyAgreementException

Encodes a public key into the message.

Parameters:

k - the public key to encode.

Throws:

KeyAgreementException - if an encoding size constraint is violated.

writePrivateKey

public void writePrivateKey(java.security.PrivateKey k)
                     throws KeyAgreementException

Encodes a private key into the message.

Parameters:

k - the private key to encode.

Throws:

KeyAgreementException - if an encoding size constraint is violated.

writeMPI

public void writeMPI(java.math.BigInteger val)
              throws KeyAgreementException

Encodes an MPI into the message.

Parameters:

val - the MPI to encode.

Throws:

KeyAgreementException - if an encoding size constraint is violated.

writeString

public void writeString(java.lang.String s)
                 throws KeyAgreementException

Encodes a string into the message.

Parameters:

s - the string to encode.

Throws:

KeyAgreementException - if the UTF8 encoding is not supported on this platform, or if an encoding size constraint is violated.
