MacGPG2: bad signature warning, etc

Baruch's Avatar


31 Oct, 2017 02:24 PM

I am getting a warning that signature of messages I am sending out is bad or wrong and that the message “may have been modified” well, I sent it, so I am the only one who could have modified it, unless something is modifying the message between the time I click send (in apple mail btw) and when it actually sends. I have to also add that I am no longer getting any key phrase popup dialog I used to get whenever I wanted to send or decrypt mail. I don’t know what setting I have to set to get that back but that might be an indication of the problem.

to have encrypted communications like before

    Hi Baruch,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    In the latest release we have enabled "Store in Keychain" by default, since we found that it made using GPG Suite a lot easier for many of our users.
    This also means however, that if you have never manually changed this setting before yourself, "Store in Keychain" is now enabled by default on your computer as well.
    In order to revert back, you can change this setting in GPG Suite Preferences.

    So if you want to revert, open System Preferences > GPG Suite Preferences untick the Store in keychain option and press the "Delete…" button to clear stored passwords.

    Regarding the verified signatures: Are you able to reproduce the behavior when sending yourself a signed only (not encrypted) test message? Are you using MS exchange or could there be an exchange server involved on the receiving end in cases where the messages get modified?
