Right­click on the file and choose Decrypt and verify, as shown in Figure 1.

2. Perform the action

If you are verifying a file with a detached signature, check the checkmark 'Input file is a detached signature' and click on the folder icon button to choose the detached signature file.

When you are ready to decrypt and/or verify the file click on Decrypt/Verify button.
