Hashing Module Level Design

Component overview

The Hashing module provides one-way hashing functions. Hashing functions are used to create a fixed-length representation of a block of data so that when the data changes the hash value does not match. The hash value is also known as a (message) digest.

A hashing function is generally used for creating a hash message authentication code (HMAC) when sending a message. Such a HMAC can be used in combination with a previously exchanged symmetric key as a message integrity and authentication control.

With this module you can thus:

  • Create a hash value/message digest for a file, a stream or a buffer.
  • Create a HMAC for a stream or a buffer.
