💖 EVP_DESX_CBC(3ossl) — aka the OpenSSL DES-X cipher page, but make it make sense 💖

okay bestie, welcome to the EVP_DESX_CBC manual page from the OpenSSL fam 🫶 this is the one that tells you all about EVP_desx_cbc, and yes it's a real function, and yes it's giving very specific cryptographic energy. let's get into it ✨

🎀 NAME 🎀

EVP_desx_cbc — the EVP DES-X cipher, no cap 💅

✨ SYNOPSIS ✨

lowkey just one include and one function, we love a minimal moment:

#include <openssl/evp.h>

const EVP_CIPHER *EVP_desx_cbc(void);

🌸 DESCRIPTION 🌸

So. EVP_desx_cbc is the DES-X encryption algorithm for EVP. That's the whole vibe of it. 🦋

Heads up tho, because this part matters fr fr: all modes below use a key length of 128 bits and acts on blocks of 128-bits. Like, that's the spec, don't come for me, I'm just the messenger 💀

💫 EVP_desx_cbc()

This one is the DES-X algorithm in CBC mode. periodt.

🚨 real talk bestie: this algorithm is not provided by the OpenSSL default provider. If you wanna use it, you have to load either the OpenSSL legacy provider or another implementation. no provider, no party 🙈

Also, devs, listen up 👑 — there are negative performance implications of calling this function multiple times. So instead of spamming it like it's a group chat, consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-DES(7) instead. There's more on this in the "Performance" section of crypto(7). iykyk 💜

🍓 RETURN VALUES 🍓

These functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. If you wanna know what's inside that EVP_CIPHER structure, go peek at EVP_CIPHER_meth_new(3) for the details. slay 🌈
