Perhaps the file is signed by an ECDH key? I can only guess. You might want to try the --list-packets option on the encrypted message.

Re: gpg: can't handle public key algorithm 18
Yes, I see that. However, our public key was generated by our GPG; and this file is encrypted with our public key, since there is NO missing "secret key" error. Why, then, the subject error message?

gpg: can't handle public key algorithm 18
On trying to decrypt a file, we get the subject error on failure. What does this mean? How ought we deal with this? Please, advise. Thank you. ~ Mike ___ Gnupg-users mailing list Gnupg-users@gnupg.org https://lists.gnupg.org/mailman/listinfo/gnupg-users
