gpg-expire-warner

Crates.io Crates.io license Build status

Prints a warning when GPG keys are about to expire, and optionally helps update their expiration time.

Example

$ exec bash The following GPG keys will expire soon: 2C7D8465F19C3CDC26237087BFD86BE9948C849A: 5 days 57E0FE20CF9F7BF57769909C0252D762936969DD: -20 days

Usage

  1. Build and install using cargo:

    $ cargo install gpg-expire-warner

  2. Add something like this to your shell startup script (.bashrc or similar):

    gpg-expire-warner --days 14 \ "2C7D8465F19C3CDC26237087BFD86BE9948C849A" \ "0E70A5BEFD6E37F6EC272A025A5B6A61618EA60D" \ "57E0FE20CF9F7BF57769909C0252D762936969DD"

  3. When it's time to extend validity, you can add --expire <expire> to the command to automatically invoke gpg to update the expiration time of each key about to expire:

    ``` $ gpg-expire-warner --days 14 \ "2C7D8465F19C3CDC26237087BFD86BE9948C849A" \ "0E70A5BEFD6E37F6EC272A025A5B6A61618EA60D" \ "57E0FE20CF9F7BF57769909C0252D762936969DD" \ --expire 1y

    The following GPG keys will expire soon: 2C7D8465F19C3CDC26237087BFD86BE9948C849A: 5 days 57E0FE20CF9F7BF57769909C0252D762936969DD: -20 days Extending validity by 1y for subkeys: 2C7D8465F19C3CDC26237087BFD86BE9948C849A, 57E0FE20CF9F7BF57769909C0252D762936969DD ```

    <expire> may be any expiration time format recognized by gpg --quick-set-expire.

  4. Move on and do better things than worry about your GPG keys expiring.
