Can you decrypt a PGP message you sent?
The public key is tied to a particular person’s identity, and anyone can use it to send them a message. The sender sends their encrypted PGP session key to the recipient, and they are able to decrypt it using their private key. Using this session key, the recipient is now able to decrypt the actual message.
How do I decrypt GPG messages?

Can you tell who can decrypt a GPG file?
*: Assuming of course their private keys are kept private, nobody bribes Alice to share the winning recipe, and so on. You can’t necessarily tell who can decrypt a given GPG file by looking at it, but assuming nobody has any knowledge aside from their own private keys and the encrypted file itself, it is possible tell how many people can.
How does OpenPGP encrypt a GPG message?
It then makes a bunch of copies of the session key, and encrypts each one under a different public key, one for each recipient. It then packages all of these encrypted “key packets” along with the encrypted message using the OpenPGP container format.
Why does GPG-D-V say decryption failed?
This message can also happen if your pinentry program isn’t working properly, and thus gpg can’t get the passphrase to unlock the decryption key. This has happened to me a couple of times. If this is the case, gpg -d -v will appear to select the correct key and then just hang for a while before giving up.
How do I Check my GPG key server?
Periodically, you can ask gpg to check the keys it has against a public key server and to refresh any that have changed. You might do this every few months or when you receive a key from a new contact. The –refresh-keys option causes gpg to perform the check. The –keyserver option must be followed by the key server of your choice.
