Hello,
I am a newbie so please forgive stupid questions
but, I am trying to create a message digest using the
gcry_md_open (&md, GCRY_MD_SHA1, GCRY_MD_FLAG_HMAC).
In the documentation it states that you must call the
gcry_md_setkey to be used to set the MAC key. How do
I calculate this MAC key? What is the MAC key...does
it get generated from the message itself in
combination with another key of some sort.
Thanks
Heather
