Htdigest accesses apache-compatible digest password files. Passwords are matched to a realm where they are valid. For security, the path for a digest password database should be stored outside of the paths available to the HTTP server.
Htdigest is intended for use with WEBrick::HTTPAuth::DigestAuth and stores passwords using cryptographic hashes.
htpasswd = WEBrick::HTTPAuth::Htdigest.new 'my_password_file' htpasswd.set_passwd 'my realm', 'username', 'password' htpasswd.flush
