💖 EVP_DESX_CBC(3ossl) 💖

okay bestie, so this one lives in the OpenSSL manual, and it's literally the whole page for EVP_desx_cbc — the EVP DES-X cipher. buckle up, it's short but she's iconic 🎀

✨ NAME ✨

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

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

const EVP_CIPHER *EVP_desx_cbc(void);

🦋 DESCRIPTION 🦋

so this is the DES-X encryption algorithm, but for EVP — like, the EVP-flavoured version 🫶

quick vibe check on the numbers: all modes below use a key length of 128 bits and acts on blocks of 128-bits. yes, that's what it says, i'm just the messenger 🧚

💜 EVP_desx_cbc()

the DES-X algorithm, in CBC mode. periodt.

⚠️ okay so this is the important part: this algorithm is not provided by the OpenSSL default provider. if you wanna use it you literally have to load either the OpenSSL legacy provider or another implementation. no default-provider shortcuts, bestie 😭

also, devs — listen up 👑 — you should be aware of the negative performance implications of calling this function multiple times, and you should consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-DES(7) instead. see "Performance" in crypto(7) for further information. iykyk 🔥

⭐ RETURN VALUES ⭐

these functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. see EVP_CIPHER_meth_new(3) for details of the EVP_CIPHER structure. she gives exactly what she's supposed to 💖

aaaand that's the whole page 🎀 mwah 💋 — sign-off time: this was version 3.5.6, dated 2026-04-07, and you just read EVP_DESX_CBC(3ossl). slay, go encrypt something (with the legacy provider loaded, obviously) 🦋💅
