@owlstead Right - the dgst function has a -sign option to "digitally sign the digest" with a private key. I believe that does protect it against alteration.

comment Okay to use OpenSSL to encrypt then sign a message?
I'm going to follow those steps, but I think none of the issues matter in my case. I don't care who knows that the sender signed the message (unless that causes additional problems I don't know about), and the recipient does not trust the message unless it is from the trusted sender.
