out
private java.io.ByteArrayOutputStream out
- The internal output stream.
| Constructor Detail |
OutgoingMessage
public OutgoingMessage()
| Method Detail |
toByteArray
public byte[] toByteArray()
throws KeyAgreementException
Returns the encoded form of the current message including the 4-byte length header.
wrap
public byte[] wrap()
throws KeyAgreementException
Returns the encoded form of the current message excluding the 4-byte length header.
writePublicKey
public void writePublicKey(java.security.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
writePrivateKey
public void writePrivateKey(java.security.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
writeMPI
public void writeMPI(java.math.BigInteger val) throws KeyAgreementException
Encodes an MPI into the message.
writeString
public void writeString(java.lang.String s) throws KeyAgreementException
Encodes a string into the message.
writeKey
private void writeKey(java.security.Key k) throws KeyAgreementException
getKeyType
private int getKeyType(java.security.Key k) throws KeyAgreementException
