💅 NAME 💅

okay so bestie, this page is the whole ARIA cipher squad in OpenSSL, and the manual name is EVP_ARIA_128_GCM(3ossl) — yes it's named after the GCM one but it's actually the group chat for all of them, iykyk. Here's everyone in the lineup, no cap, all 30 of them:

  • CBC girlies: EVP_aria_128_cbc, EVP_aria_192_cbc, EVP_aria_256_cbc
  • CFB (the 128-bit shift ones): EVP_aria_128_cfb, EVP_aria_192_cfb, EVP_aria_256_cfb
  • CFB with a 1-bit shift: EVP_aria_128_cfb1, EVP_aria_192_cfb1, EVP_aria_256_cfb1
  • CFB with an 8-bit shift: EVP_aria_128_cfb8, EVP_aria_192_cfb8, EVP_aria_256_cfb8
  • CFB, 128-bit shift, the loud version: EVP_aria_128_cfb128, EVP_aria_192_cfb128, EVP_aria_256_cfb128
  • CTR cuties: EVP_aria_128_ctr, EVP_aria_192_ctr, EVP_aria_256_ctr
  • ECB era: EVP_aria_128_ecb, EVP_aria_192_ecb, EVP_aria_256_ecb
  • OFB girlies: EVP_aria_128_ofb, EVP_aria_192_ofb, EVP_aria_256_ofb
  • CCM mode: EVP_aria_128_ccm, EVP_aria_192_ccm, EVP_aria_256_ccm
  • GCM mode: EVP_aria_128_gcm, EVP_aria_192_gcm, EVP_aria_256_gcm

and what is it, like, for? it's giving — EVP ARIA cipher. that's the whole vibe. 🦋

✨ SYNOPSIS ✨

#include <openssl/evp.h>

const EVP_CIPHER *EVP_ciphername(void)

so <cyan>EVP_ciphername</cyan> is just a lil placeholder bestie — swap it out for any of the cipher functions above, like EVP_aria_128_cbc for example. it's a stand-in, not a real function, don't come for me. 🫶

🌸 DESCRIPTION 🌸

the ARIA encryption algorithm, but for EVP. that's the tea. 🔥

Group one — the classic modes:

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. periodt. 💅

Group two — the AEAD icons:

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). ⭐
okay so heads up bestie: these ones are extra — they need additional control operations to actually function correctly. go read the "AEAD INTERFACE" in EVP_EncryptInit(3) section for the details, fr fr. don't just rawdog it. 🙈

👑 NOTES 👑

devs, listen up: there are negative performance implications of calling these functions multiple times. like, it's not the move. 😭 instead, consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-ARIA(7) — see "Performance" in crypto(7) for further information. main character energy is fetching, not re-calling. 💜

💀 RETURN VALUES 💀

these functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. for the details of the EVP_CIPHER structure, go look at EVP_CIPHER_meth_new(3). that's where the lore lives. 📖

and that's the whole page bestie, tysm for reading 🥰 this was OpenSSL 3.5.9, dated 2026-09-29 — slay, stay encrypted, and don't forget to EVP_CIPHER_fetch. bye babes 💖✨🧚
