Anyone that sends you an email encrypted with your public key, the Atomichelix
OpenPGP application will detect the encryption when the message is opened and
prompt you to decrypt it. Below are the steps to decrypted an incoming email.
When you open an email message that was encrypted using your public
key, the prompt shown here will ask you if you wish to decrypt it.
If you select "Yes" to decrypt the message, you will be prompted for
your passphrase for that private key (as seen here).
If you do not enter the correct passphrase within three attempts, the
application will not decrypt the message. However, if you do enter
the correct passphrase for that associated private key, your message
will be decrypted and displayed normally (like the message shown here).
