Authen:...XTERNAL(3)

💖 Authen::SASL::Perl::EXTERNAL — bestie, it's the External Authentication class 💖

okay so this is a Perl manual page, from the User Contributed Perl Documentation section (section 3, the library-calls one, iykyk), and it's literally called Authen::SASL::Perl::EXTERNAL. grab a snack, we're doing auth 💅

---

✨ VERSION ✨

This is version 2.2100. that's the vibe. that's the number. periodt.

---

🌸 SYNOPSIS 🌸

here's the whole flex, in code, untouched and iconic:

  use Authen::SASL qw(Perl);

  $sasl = Authen::SASL->new(
    mechanism => 'EXTERNAL',
    callback  => {
      user => $user
    },
  );

that's it. that's the whole entrance. use the module, spin up a $sasl object with Authen::SASL->new, hand it mechanism => 'EXTERNAL', and pass a callback hashref that carries your user. slay ✨

---

🦋 DESCRIPTION 🦋

so what is this actually doing? this method implements the client part of the EXTERNAL SASL algorithm, exactly as described in RFC 2222. no cap, that's the whole description. it's the client side, the algorithm is EXTERNAL, the spec is RFC 2222. 👑

🎀 CALLBACK 🎀

the callbacks used are — yes, just the one, she's lowkey minimalist:

• user — the username to be used for authentication. that's it, that's the callback. it's giving "one job, done perfectly" 💅
