💖 srptool(1) 💖

okay so bestie, welcome to the User Commands section of the manual, and today's main character is srptool, aka the GnuTLS SRP tool 🌸. yes it's a whole tool. yes it has opinions. let's go 🫶

✨ SYNOPSIS ✨

srptool [-flags] [-flag [value]] [--option-name[[=| ]value]]
heads up: All arguments must be options. like, every single one. no loose little positional strays wandering around, bestie 💅

🦋 DESCRIPTION 🦋

It's a simple program that emulates the programs in the Stanford SRP (Secure Remote Password) libraries, except it does it using GnuTLS. so it's giving "the classic, but rehomed" 🎀

It is intended for use in places where you don't expect SRP authentication to be the used for system users. (yes, that's the sentence, she's a little wobbly but she's ours 😭)

In brief, to use SRP you need to create two files. These are:

  • the password file that holds the users and the verifiers associated with them
  • the configuration file to hold the group parameters (called tpasswd.conf)

so like, two files. one for the people, one for the math. slay ✨

👑 OPTIONS 👑

  • -d num, --debug=num — Enable debugging. This option takes an integer number as its argument. The value of num is constrained to being:
    • in the range 0 through 9999

Specifies the debug level. crank it up and watch the little guy yap 🔥

  • -i num, --index=num — This option takes an integer number as its argument. The default number for this option is:
    • 3
  • -u str, --username=str — the username, bestie, you know the vibe 💜
  • -p str, --passwd=str — the password. keep it safe, keep it secret, keep it cute 🙈
  • -s num, --salt=num — This option takes an integer number as its argument. seasoning for your hashes, lowkey essential 🍓
  • --verify — Verifies the password provided against the password file. it's giving "vibe check, but for credentials" ⭐
  • -v str, --passwd-conf=str — Specify a filename or a PKCS #11 URL to read the CAs from.
  • --create-conf=str — Generate a password configuration file.

This generates a password configuration file (tpasswd.conf) containing the required for TLS parameters.

  • -v arg, --version=arg — Output version of program and exit. The default mode is v, a simple version. The c mode will print copyright information and n will print the full copyright notice. (yes, -v is doing double duty here — the page says so, not me 😭)
  • -h, --help — Display usage information and exit. your girl never leaves you hanging 🫶
  • -!, --more-help — Pass the extended usage information through a pager. the deluxe edition, no cap 📖✨

🧪 EXAMPLES 🧪

To create tpasswd.conf which holds the g and n values for SRP protocol (generator and a large prime), run:

$ srptool --create-conf /etc/tpasswd.conf

This command will create /etc/tpasswd and will add user 'test' (you will also be prompted for a password). Verifiers are stored by default in the way libsrp expects.

$ srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf -u test

This command will check against a password. If the password matches the one in /etc/tpasswd you will get an ok.

$ srptool --passwd /etc/tpasswd --passwd-conf /etc/tpasswd.conf --verify -u test

🌈 EXIT STATUS 🌈

One of the following exit values will be returned:

  1. 0 (EXIT_SUCCESS) — Successful program execution. it ate. 💅
  2. 1 (EXIT_FAILURE) — The operation failed or the command syntax was not valid. it did not eat. 💀
