gpg-expire-warner

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.
