Simon Butcher | 00aea9a | 2016-03-17 00:30:35 +0000 | [diff] [blame] | 54 | * The Message Digest (MD) or Hashing module provides one-way hashing |
| 55 | * functions. Such functions can be used for creating a hash message |
| 56 | * authentication code (HMAC) when sending a message. Such a HMAC can be used |
| 57 | * in combination with a private key for authentication, which is a message |
| 58 | * integrity control. |
Paul Bakker | dcbfdcc | 2013-09-10 16:16:50 +0200 | [diff] [blame] | 59 | * |
| 60 | * All hash algorithms can be accessed via the generic MD layer (see |
