💅 NAME 💅

Okay bestie, welcome to EVP_ARIA_128_GCM(3ossl) — the OpenSSL manpage for the whole ARIA cipher squad 🎀

This page covers EVP ARIA cipher, aka the entire EVP_aria_* family. Here's the full lineup, and yes, every single one of them is invited to the party:

EVP_aria_128_cbc, EVP_aria_192_cbc, EVP_aria_256_cbc, EVP_aria_128_cfb,
EVP_aria_192_cfb, EVP_aria_256_cfb, EVP_aria_128_cfb1,
EVP_aria_192_cfb1, EVP_aria_256_cfb1, EVP_aria_128_cfb8,
EVP_aria_192_cfb8, EVP_aria_256_cfb8, EVP_aria_128_cfb128,
EVP_aria_192_cfb128, EVP_aria_256_cfb128, EVP_aria_128_ctr,
EVP_aria_192_ctr, EVP_aria_256_ctr, EVP_aria_128_ecb, EVP_aria_192_ecb,
EVP_aria_256_ecb, EVP_aria_128_ofb, EVP_aria_192_ofb, EVP_aria_256_ofb,
EVP_aria_128_ccm, EVP_aria_192_ccm, EVP_aria_256_ccm, EVP_aria_128_gcm,
EVP_aria_192_gcm, EVP_aria_256_gcm

Thirty functions, zero skips, we love to see it 💖

✨ SYNOPSIS ✨

Like, the entire vibe in two lines:

#include <openssl/evp.h>

const EVP_CIPHER *EVP_ciphername(void)

So <cyan>EVP_ciphername</cyan> is literally just a placeholder stand-in for any of the cipher functions described on this page — like EVP_aria_128_cbc, bestie. Don't go looking for an actual function called EVP_ciphername, she's a concept, not a real girl 🫶

🦋 DESCRIPTION 🦋

The ARIA encryption algorithm, for EVP. That's the whole premise. Now let's break it down 🌈

🍓 the classic modes (non-AEAD)

  • EVP_aria_128_cbc(), EVP_aria_192_cbc(), EVP_aria_256_cbc(), EVP_aria_128_cfb(), EVP_aria_192_cfb(), EVP_aria_256_cfb(), EVP_aria_128_cfb1(), EVP_aria_192_cfb1(), EVP_aria_256_cfb1(), EVP_aria_128_cfb8(), EVP_aria_192_cfb8(), EVP_aria_256_cfb8(), EVP_aria_128_cfb128(), EVP_aria_192_cfb128(), EVP_aria_256_cfb128(), EVP_aria_128_ctr(), EVP_aria_192_ctr(), EVP_aria_256_ctr(), EVP_aria_128_ecb(), EVP_aria_192_ecb(), EVP_aria_256_ecb(), EVP_aria_128_ofb(), EVP_aria_192_ofb(), EVP_aria_256_ofb() — ARIA for 128, 192 and 256 bit keys, in these modes: CBC, CFB with 128-bit shift, CFB with 1-bit shift, CFB with 8-bit shift, CTR, ECB and OFB. All the shift flavors, all the key sizes, no crumbs 💅

🌸 the AEAD girlies (CCM + GCM)

  • EVP_aria_128_ccm(), EVP_aria_192_ccm(), EVP_aria_256_ccm(), EVP_aria_128_gcm(), EVP_aria_192_gcm(), EVP_aria_256_gcm() — ARIA for 128, 192 and 256 bit keys in CBC-MAC Mode (CCM) and Galois Counter Mode (GCM) ⭐
⚠️ Heads up bestie: these ciphers require additional control operations to function correctly. Go read the "AEAD INTERFACE" section in EVP_EncryptInit(3) for the details — don't just yeet them in raw 😭

🎀 NOTES 🎀

Developers, listen up: there are negative performance implications of calling these functions multiple times, and you should lowkey consider using EVP_CIPHER_fetch(3) together with EVP_CIPHER-ARIA(7) instead. See "Performance" in crypto(7) for more info. Not me warning you about the hot path 🔥

👑 RETURN VALUES 👑

These functions return an EVP_CIPHER structure containing the implementation of the symmetric cipher. If you wanna know what's inside that struct, check EVP_CIPHER_meth_new(3) — she has the details 💜
