CRC32(1)

💖 crc32(1) — General Commands Manual 💖

okay bestie, welcome to the crc32 page, straight out of the General Commands Manual section of the terminal ✨ it's short, it's sweet, and it's about to hand you a checksum. let's go 🫶

🌸 NAME 🌸

crc32 — compute CRC-32 checksums for the given files

✨ SYNOPSIS ✨

crc32 filename [ filename ... ]

💅 DESCRIPTION 💅

okay so crc32 is a simple utility that calculates the CRC-32 checksum for each of the given files. you hand it files, it hands you checksums. that's the whole vibe. 🎀

🚨 important note, no cap: the CRC-32 checksum is merely used for error detection in transmission and storage. it is not intended to guard against the malicious modification of files — i.e., it is not a cryptographic hash. so like… it will catch a corrupted bit from a flaky download, but it will not catch a hater who's out here editing your files on purpose. know the difference bestie, it's giving security literacy 🔥

also, fun fact: this utility is supplied with the Archive::Zip module for Perl 🧚

👑 AUTHOR 👑

the Archive::Zip module was written by Ned Konz 👑

this manual page was prepared by Ben Burton <bab@debian.org> for the Debian GNU/Linux system — but it may be used by others 🫶 (yes, that's literally what it says, sharing is caring)

and that's the whole page!! this version dropped back on June 21, 2005, and it's part of the CRC32(1) era of the General Commands Manual — iconic, timeless, still checksumming 💅💖 mwah, go verify some files bestie ✨🌈
