Import PGP keys with PGP Encryption Desktop for Windows (Symantec Encryption Desktop).
When importing a PGP Key Pair, the following message appears:
"Some of the imported keys are private keys. The trust values of these keys must be set manually via the Key Properties dialog."
When running into the screenshot message above, the trust values for PGP Key pairs must be set. To do this, you simply double-click the key, click on Trust, and set to "Implicit". This will give the key full trust at a keypair level. For more details on importing keys, see the rest of this article.
This article details how to import PGP keys using PGP Encryption Desktop. You can import PGP public keys and PKCS-12 X.509 certificates (a digital certificate format that most web browsers use) to your PGP Keys keyring. You can also import Privacy Enhanced Mail (PEM) format X.509 certificates from your browser by copying and pasting into your public keyring.
Here are some methods to import a PGP public key and add it to your keyring:
Double-clicking the file on your system. If PGP Encryption Desktop recognizes the file format, it opens and asks if you want to import the key(s) in the file.
Choosing to import the key file in PGP Encryption Desktop.
Dragging the file containing the public key onto the PGP Keys window.
Note: After importing keys to Encryption Desktop, you may need to Sign or change the Trust level of the key.
TIP: If you have imported a PGP Key and you can't encrypt to it. Sometimes having the recipient export the key and re-send to you and then re-import the key can fix the issue.
