Expand description

HMAC-SHA256 algorithm.

The input message * in - is authenticated using the key * key - . The computed authenticator is put into * r - . To verify the authenticator, the recipient needs to recompute the HMAC authenticator and can then compare it with the received authenticator.

  • r - HMAC output.
  • key - HMAC key.
  • key_len - Length of * key - .
  • in - Input data.
  • in_len - Length of * in - .
