+/**
+ * @addtogroup hashing_module Hashing module
+ *
+ * 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:
+ * - MD5 128-bit one-way hash function 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.
