The Open PGP Encrypt and Sign option encrypts and authenticates the file. The file will be encrypted with the public key of the person to whom it is sent and it will be signed with your PGP digital signature created from your own secret key. This process combines the Encrypt and Sign functions.
The duration of the Open PGP encryption and signing depends on the number of selected files. While the files are being encrypted and signed, a status bar displays the task progress. When complete, a dialog box shows a results summary.
On the Open PGP Tasks tab, navigate to the file or folder you would like to encrypt and sign. Then from the toolbar, click the Encrypt & Sign icon.
