openssl hmac using aes-256-cbc
- by Ryan
Hello,
I am trying to take an AES HMAC of a file using the openssl command line program on Linux. I have been looking at the man pages but can't quite figure out how successfully make a HMAC. I can encrypt a file using the enc command with openssl however I can't seem to create a HMAC. The encryption looks like the following:
openssl enc -aes-256-cbc -in plaintext -out ciphertext
Any advice or tutorials would be wonderful
