Describe your problem. Add as much detail as possible.

What did you expect instead

Describe steps leading to the problem. client has shared the gpg public keys to send the encrypted files to them
i have imported the gpg keys and added the ultimate trust on it.
now we have a requirement that
we need to signed the file with myUAT Private Key

I have signed the gpg key provided by them with the help of gpg -edit-key command
but it is not working at their side
so i tried to encrypt the file with the help of sign
gpg --sign --encrypt --armor --recipient CEMailBx DCFAFF94.txt
but it is giving me popup to enter the passphrase which would be the problem while doing automation for me.

Please suggest some solution so that i can encrypt the file along with sign without passphrase.
