OutgoingMessage
public OutgoingMessage()
The basic constructor. Object is special, because it has no
superclass, so there is no call to super().
wrap
public byte[] wrap()
throws KeyAgreementException Returns the encoded form of the current message excluding the 4-byte length
header.
writePrivateKey
public void writePrivateKey(PrivateKey k)
throws KeyAgreementException Encodes a private key into the message.
When a private key is encoded into an outgoing message, the byte array of
the encoded key --according to its encoding/decoding format specified when
the key was first instantiated-- are put in the message (a) preceeded by
one byte representing both the type of key (upper 4-bit) and the identifier
of the format used (lower 4-bit), and (b) preceeed by a 4-byte entity
representing the total length, excluding these 4 bytes, of the bytes
representing the encoded key and the one-byte representing the key-type and
format; i.e.
key --> 4-byte-length || 1-byte-type-and-format || encoded-key-bytes
k - the private key to encode.
writePublicKey
public void writePublicKey(PublicKey k)
throws KeyAgreementException Encodes a public key into the message.
When a public key is encoded into an outgoing message, the byte array of
the encoded key --according to its encoding/decoding format specified when
the key was first instantiated-- are put in the message (a) preceeded by
one byte representing both the type of key (upper 4-bit) and the identifier
of the format used (lower 4-bit), and (b) preceeed by a 4-byte entity
representing the total length, excluding these 4 bytes, of the bytes
representing the encoded key and the one-byte representing the key-type and
format; i.e.
key --> 4-byte-length || 1-byte-type-and-format || encoded-key-bytes
k - the public key to encode.
