TlsMac
(Digest digest, byte[] key_block, int offset, int len)
Generate a new instance of an TlsMac.
Parameters
| digest
| The digest to use. |
| key_block
| A byte-array where the key for this mac is located. |
| offset
| The number of bytes to skip, before the key starts in the buffer. |
| len
| The length of the key.

Public Methods
public
byte[]
calculateMac
(short type, byte[] message, int offset, int len)
Calculate the mac for some given data.
TlsMac will keep track of the sequence number internally.
Parameters
| type
| The message type of the message. |
| message
| A byte-buffer containing the message. |
| offset
| The number of bytes to skip, before the message starts. |
| len
| The length of the message. |
Returns
- A new byte-buffer containing the mac value.
