Expand description
HMAC-SHA512 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
- .
