EVP_ARIA_128_GCM(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

🦋 EVP_ARIA_128_GCM — the ARIA cipher squad (3ossl girlies rise) ✨

okay so first things first, this is page EVP_ARIA_128_GCM(3ossl) from the OpenSSL manual — yes the title only names one of them but bestie this whole page is a group chat, not a solo. Let's meet the whole friend group 💖

🌸 NAME

Say hi to the entire ARIA cipher lineup, no cap:

  • 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

and they all fall under one iconic umbrella: EVP ARIA cipher 👑

🎀 SYNOPSIS

#include <openssl/evp.h>

const EVP_CIPHER *EVP_ciphername(void)

real talk: EVP_ciphername is just a placeholder token, standing in for literally any of the cipher functions described here — like EVP_aria_128_cbc for example. so when you see it, mentally swap in whichever one you actually want 🫶

💜 DESCRIPTION

The ARIA encryption algorithm for EVP. periodt.

✨ the non-AEAD girlies (CBC, CFB, CTR, ECB, OFB)

  • 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()

— that's ARIA for 128, 192 and 256 bit keys in the following modes: CBC, CFB with 128-bit shift, CFB with 1-bit shift, CFB with 8-bit shift, CTR, ECB and OFB. a whole little wardrobe of modes, pick your fit 💅

🔥 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()

— that's 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. seriously. check out the "AEAD Interface" section in EVP_EncryptInit(3) for the deets, iykyk.

🌈 NOTES

okay listen — devs should be aware of the negative performance implications of calling these functions multiple times 😭 and should consider using EVP_CIPHER_fetch(3) with EVP_CIPHER-ARIA(7) instead. that's the move. see "Performance" in crypto(7) for further information. fr fr, don't spam-call these.

💖 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. it's giving "here's your cipher, wrapped and ready" 🎁
