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. Note: < 1 user> is the user ID, portion of the user ID, or the key ID of the key whose expiration date is being removed. < 2 pass> is the passphrase of the key.  Use the following commands to update the expiration date of your PGP key.
In order to remove the need to constantly re-sign applications with new certificates, ClickOnce supports timestamp. When an application is signed with a timestamp, its certificate will continue to be accepted even after expiration, provided the timestamp is valid. This allows ClickOnce applications with expired certificates, but valid timestamps, to download and run. It also allows installed applications with expired certificates to continue to download and install updates. To include a timestamp in an application server, a timestamp server must be available.
