Crypt:...om::XS(3pm)

💜 Crypt::SysRandom::XS — the Perl manual, but make it cute

okay so bestie, this is Crypt::SysRandom::XS (the manual page itself goes by Crypt:...om::XS(3pm), which is giving truncated-name energy but we move 💅). It's the Perl interface to system randomness, specifically the XS version — the one that talks straight to C. no cap, it's the real deal ✨

🌸 VERSION

version 0.011 — she's v0.011 and she's thriving 🫶

🦋 SYNOPSIS

like, the whole vibe in four lines:

use Crypt::SysRandom::XS 'random_bytes';
my $random = random_bytes(16);

boom. sixteen random bytes. iconic. 👑

🎀 DESCRIPTION

So here's the tea ☕ — this module uses whatever C interface is available to procure cryptographically random data from the system. That's it. That's the whole personality. She finds the best available system hookup and gets you the good stuff 💖

🔥 FUNCTIONS

random_bytes($count)

This one will fetch you a string of $count random bytes containing cryptographically secure random data. literally all it does, and it does it flawlessly 🌟

⭐ BACKENDS

okay this part is lowkey the coolest — at build-time, it tries the following backends in order (first one that works wins, main character energy only 🎯):

• getrandom — this backend is available on Linux, FreeBSD and Solaris 🌈
• arc4random — this interface is supported on most BSDs and Mac 🍓
• BCryptGenRandom — this backend is available on Windows (Vista and newer) 🪟
• rdrand64 — this is available on x86_64 architectures using most compilers 💻
• rdrand32 — this is available on x86_64 and x86 architectures using most compilers 💻

ngl, the order matters — it's not just gonna pick a random (lol) backend, it goes down the list and grabs the first one that's available on your platform 🙈
