Hey guys,

I have all relevant keys imported and set the correct prefs, but new mails don’t get encrypted. The button in the upper right doesn’t turn green and mails stay in plain text.

Whats wrong?

    Hi Danny,

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

    Have you closely followed our Getting Started Tutorial regarding sending a first test mail?

    Note that one requirement to encrypt an email is to have a recipient in the To: field for whom you do have a public key in your GPG Keychain.

    All the best,

    Hello Steve,

    sure, I used it for years under 10.9 and everything was fine. I have my recipient's public keys in a directory, imported them and my own key as well.

    I found out that one of my send-addresses works. but the other, which is included in my key as well (at least the GPG keychain tells me so), doesn't.

    Why does it actually depend on MY key whether I can encrypt a mail, when the crypto is applied by the recipient's public key?

    Hey Danny,

    any outgoing mail is also encrypted with your own public key. Otherwise you would not be able to read any encrypted mails after sending them out.

    First, let's check if your key is ok:

    1. open GPG Keychain
    2. double click your sec/pub key
    3. create a screenshot of the key tab (⇧⌘4 + drag w mouse)
    4. create a screenshot of the subkey tab
    5. attach both screenshots to your discussion by visiting it in your browser

    Should your key have expired, please re-new the expiration date.

    Should your subkey be expired, please create a new subkey.

    1. navigate to the subkey tab
    2. click the "+" button below
    3. confirm with "Generate subkey"

    After that send a signed and encrypted test mail to yourself. Are you able to decrypt and verify the signature successfully?

    In case your key resides on the public key servers, don't forget to upload your updated key, so that the changes are reflected on the key servers.

    Best regards,
