This error can take place when creating a PGP Zip with a large file or numerous large files and the passphrase option setting is configured to save your passphrase for a short period of time. This occurs when the passphrase is set to be saved for a time interval which is shorter than the time it takes to encrypt the file(s).
The default interval for saving your passphrase for a period of time is 2 minutes. To workaround the issue, increase the amount of time your passphrase is cached.
To change the passphrase cache time setting
- Click the PGP Tray icon in the Windows System Tray.
- Select Options. The PGP Options are displayed.
- On the General tab in My Passphrase, change the time interval to a larger value.
- Click OK.
