This article describes how to update the expiration date of a key with PGP Command Line. The expiration date of your key can be updated if the key has a specified expiration date. You can update the expiration date, the number of days, or remove the expiration date for your PGP key. When specifying the date for the key to expire, the date format is yyyy-mm-dd.

Use the following commands to update the expiration date of your PGP key.
