Password Safe is a password database utility. Like many other such
products, commercial and otherwise, it stores your passwords in an
encrypted file, allowing you to remember only one password (the "safe
combination"), instead of all the username/password combinations that
you use.

A private certificate authority (X.509 & SSH) & ACME server for secure
automated certificate management, so you can use TLS everywhere & SSO for SSH.

zsh shell completions for step-cli.

A zero trust swiss army knife for working with X509, OAuth, JWT, OATH OTP, etc.

KMS plugin.
