According to qistoph's blog (and dave_thompson_085's comment), to sign a message. Below is a description of the steps to take to verify a PKCS#7 signed data message that is signed with a valid signature. Right, so you agree with what I said in previous comment: it's not "sign message digest" as you used in your answer, it's just "sign message" as "sign message digest" would imply "encrypt digest of message digest" :) anyway, the above commands do not output PKCS7 objects, just plain signature. The -verify argument tells OpenSSL to verify signature using the provided public key. You can achieve this using the following commands: openssl base64 -d -in -out /tmp/sign.sha256 openssl dgst -sha256 -verify -signature /tmp/sign.sha256 But with OpenSSL cms -verify it is not working as expected or it is not supported. with openssl smime -sign -text.... it will actually be signing, Is it possible to use openssl to sign a normal text file (as it is)?
