A script for my own convenience to change all my passwords. It changes the passphrases of my current user, root, my SSH key, my LUKS GPG key, and my personal GPG key. Prefix a space before running this command to avoid storing your passwords in your shell history.
I'm not a developer by any means, and you may find this repository a comical attempt to change passphrases. And you're probably right, so feel free to:
- Not use it;
- Show me how to make it better (you are encouraged!).
$ ./chpass.sh -h
chpass, version 0.1
Usage: ./chpass.sh -o OLD_PASS -n NEW_PASS [option] ...
-h, --help display this help and exit
-o, --old-passphrase specify your old passphrase (e.g.
correcthorsebatterystaple)
-n, --new-passphrase specify your new passphrase (e.g.
correcthorsebatterystaple)
Options:
-u, --username override user name (e.g. larry). Otherwise
we assume user who called script.
-l, --login change login passphrase
-r, --root change root's passphrase
-s, --ssh-key specify your SSH key to change your
passphrase of (e.g. ~/.ssh/id_ed25519)
-L, --luks-gpg-key specify your LUKS GPG key in /boot to change
your passphrase of (e.g. /boot/root.gpg)
-g, --gpg-key-id specify your GPG key ID to change your
passphrase of (e.g.
26D3D565A520CC894E457D0F5922172F920C075A).
does not work with --old-passphrase, or
--new-passphrase and will prompt for both.
$ sudo ./chpass.sh -o 'oldpass' -n 'newpass' -l -r -s ~/.ssh/id_ed25519 \
-L /boot/root.gpg

Changing passphrases complete.
- bash (app-shells/bash);
- coreutils (sys-apps/coreutils);
- gpg (app-crypt/gnupg);
- openssh (net-misc/openssh);
- shadow (sys-apps/shadow).
- Figure out a way to change personal GPG key non-interactively. Couldn't get it to work with
gpgitself,gpg-agent(pinentry loopback), norexpect.
