Which of our tools is giving you problems? GPG Keychain v1.4.6 (1514)

Describe your problem. Add as much detail as possible.

looking on how to verify signature of a file (veracrypt.dmg) in their website (, it says in the step 4:
4- Sign the imported key with your private key to mark it as trusted,
Note: If you skip this step and attempt to verify any of our PGP signatures, you will receive an error message stating that the signing key is invalid.
so, how to do that using GPG Keychain,

    Hi gambeta,

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

    This KB explains how to verify downloaded files:

    Verifying a file with a public key that has not been signed should not result in an error. The signature would then show with "undefinied trust" as shown in the KB article.

    Randomly signing the key without verifying it, would not be good practice. But is possible. This KB-article explains how to verify and sign a key.

    Hope this helps,
