=head1 DESCRIPTION |
45
|
|
|
|
|
|
|
|
46
|
|
|
|
|
|
|
This module implements the Serpent cipher. Provided interface is compliant with L module. |
47
|
|
|
|
|
|
|
|
48
|
|
|
|
|
|
|
B This module implements just elementary "one-block-(en|de)cryption" operation - if you want to |
49
|
|
|
|
|
|
|
encrypt/decrypt generic data you have to use some of the cipher block modes - check for example |
50
|
|
|
|
|
|
|
L, L or L (which will be slower). |
