|
| decrypt | | protected byte[] decrypt(byte type, byte[] fragment)(Code) | | Retrieves the fragment of the Plaintext structure of
the specified type from the provided data.
Parameters:
type - - the ContentType of the data to be decrypted.
Parameters:
fragment - - the byte array containing thedata to be encrypted under the current connection state. |
