Sessio...te::MD5(3pm)

✨ Apache::Session::Generate::MD5 — the perl doc, but make it cute ✨

okay bestie, pull up a chair 🫶 this is the manual page for Apache::Session::Generate::MD5, part of the User Contributed Perl Documentation (manual section 3pm, for the perl girlies who read docs for fun 💅). It's literally all about making random object IDs with MD5, and honestly? iconic.

🌸 NAME 🌸

Apache::Session::Generate::MD5 — use MD5 to create random object IDs 💖

---

✨ SYNOPSIS ✨

like, here's the vibe:

use Apache::SessionX::Generate::MD5;

$id = Apache::SessionX::Generate::MD5::generate($string);

that's it. that's the whole flex. 🎀

💫 DESCRIPTION 💫

so this module is the one that fulfills the ID generation interface of Apache::SessionX — it's the girl who shows up and does the job. no cap.

If you don't hand it the $string argument, the IDs get generated using a two-round MD5 of:

• a random number 🎲
• the time since the epoch ⏰
• the process ID 🧚
• the address of an anonymous hash 🫧

and the resultant ID number is highly entropic on Linux and other platforms that have good random number generators. 🔥 slay.

real talk though: you are encouraged to investigate the quality of your system's random number generator if you're using the generated ID numbers in a secure environment. don't just trust the vibes, bestie. 🔐

If you do give it $string, the ID is simply the MD5 hash of that string. easy. 💜

This module can also examine session IDs to make sure they are, in fact, session ID numbers and not evil attacks 😭💀. And the reader is encouraged to consider the effect of bogus session ID numbers in a system which uses these ID numbers to access disks and databases. like… think about it. the consequences. 🙈

This module takes one argument in the usual Apache::Session style. The argument is IDLength, and the value — between 0 and 32 — tells this module where to truncate the session ID. ✂️

Without this argument, the session ID will be 32 hexadecimal characters long, which is equivalent to a 128-bit key. 👑
