drduh/Purse

Purse is a Bash shell script based on drduh/pwd.sh.

Both programs use GnuPG to manage secrets in encrypted text files. Purse is based on asymmetric (public-key) authentication, while pwd.sh is based on symmetric (passphrase-based) authentication.

Purse eliminates the need for a passphrase: plug in the YubiKey, enter PIN and touch it to access secrets.

[!IMPORTANT] A GnuPG identity is required to use Purse - see drduh/YubiKey-Guide to set one up.

Install

Purse is available for download from Releases, or directly from GitHub:

wget https://github.com/drduh/Purse/blob/master/purse.sh

Use

Run the script interactively using ./purse.sh or symlink to a directory in PATH:

• w to create a secret
• r to access a secret
• l to list all secrets
• b to create a backup archive
• h to print the help text

Options can also be passed on the command line.

Create a 20-character password for userName:

./purse.sh w userName 20

Read password for userName:

./purse.sh r userName

Passwords are stored with an epoch timestamp for revision control. The most recent version is copied to clipboard on read. To list all passwords or read a specific version of a password:

./purse.sh l

./purse.sh r userName@1574723600

Create an archive for backup:

./purse.sh b

Restore an archive from backup:

tar xvf purse*tar

Configure

See config/gpg.conf for recommended GnuPG options.

Several customizable options and features are also available, and can be configured with environment variables, for example in the shell rc file:

[!NOTE] For privacy, the recipient key ID is not included in metadata (using the GnuPG throw-keyids option).
