command line hmac with key in hex

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

Re: command line hmac with key in hex

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, Shigeo __ OpenSSL Project
