|
|
|
|
|
*
|
|
|
|
|
* The Message Digest (MD) or Hashing module provides one-way hashing
|
|
|
|
|
* functions. Such functions can be used for creating a hash message
|
|
|
|
|
* authentication code (HMAC) when sending a message. Such a HMAC can be used
|
|
|
|
|
* in combination with a private key for authentication, which is a message
|
|
|
|
|
* integrity control.
|
|
|
|
|
*
|
|
|
|
|
* All hash algorithms can be accessed via the generic MD layer (see
|
|
|
|
|
* \c mbedtls_md_setup())
|
|
|
|
|
*
|
|
|
|
|
* The following hashing-algorithms are provided:
|
|
|
|
|
* - MD2, MD4, MD5 128-bit one-way hash functions by Ron Rivest.
|
|
|
|
|
* - SHA-1, SHA-256, SHA-384/512 160-bit or more one-way hash functions by
|
|
|
|
|
* NIST and NSA.
|
|
|
|
|
*
|
|
|
|
|
* This module provides one-way hashing which can be used for authentication.
