Verify SMIME message

Overview

You can use the SMIME Verify filter to check the integrity of a Secure/Multipurpose Internet Mail Extensions (SMIME) message. This filter enables you to verify the Public Key Cryptography Standards (PKCS) #7 signature over the message.

You can select the certificates that contain the public keys to be used to verify the signature. Alternatively, you can specify a message attribute that contains the certificate with the public key to be used.
