Hi,
I tried to use openssl command to generate an HMAC with a key
contains '\0', but failed.
openssl dgst -sha1 -hmac `cat key-file` input-file
I'm happy if dgst command supports binary format like enc command.
So I appended -hmachex key in hex option as the followings:
openssl dgst -sha1

Hi,
You can achieve this using the generalised MAC interface to HMAC like this:
openssl dgst -sha1 -mac HMAC -macopt hexkey:aabbcc
I'm ashamed of my mail. Thank you for your advice.
Yours,
