EVP_CAMELLIA_128_ECB(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💖 EVP_CAMELLIA_128_ECB — the Camellia cipher era 💖

okay so bestie, welcome to the OpenSSL manual page for the Camellia cipher family. yes it says EVP_CAMELLIA_128_ECB at the top but honestly there are like twenty-four of these babies and they all live here together, so buckle up 🎀

✨ NAME ✨

EVP_camellia_128_cbc, EVP_camellia_192_cbc, EVP_camellia_256_cbc, EVP_camellia_128_cfb, EVP_camellia_192_cfb, EVP_camellia_256_cfb, EVP_camellia_128_cfb1, EVP_camellia_192_cfb1, EVP_camellia_256_cfb1, EVP_camellia_128_cfb8, EVP_camellia_192_cfb8, EVP_camellia_256_cfb8, EVP_camellia_128_cfb128, EVP_camellia_192_cfb128, EVP_camellia_256_cfb128, EVP_camellia_128_ctr, EVP_camellia_192_ctr, EVP_camellia_256_ctr, EVP_camellia_128_ecb, EVP_camellia_192_ecb, EVP_camellia_256_ecb, EVP_camellia_128_ofb, EVP_camellia_192_ofb, EVP_camellia_256_ofb — the whole Camellia cipher squad 🦋

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

const EVP_CIPHER *EVP_ciphername(void)

so EVP_ciphername is literally just a placeholder, okay? like a lil stand-in for any of the cipher functions described below — for example EVP_camellia_128_cbc. think of it like the group chat name that changes depending on who's typing 💅

💜 DESCRIPTION 💜

it's giving the Camellia encryption algorithm, but for EVP. periodt.

now for the full lineup, and yes i'm naming every single one because they all matter 🫶:

  • EVP_camellia_128_cbc()
  • EVP_camellia_192_cbc()
  • EVP_camellia_256_cbc()
  • EVP_camellia_128_cfb()
  • EVP_camellia_192_cfb()
  • EVP_camellia_256_cfb()
  • EVP_camellia_128_cfb1()
  • EVP_camellia_192_cfb1()
  • EVP_camellia_256_cfb1()
  • EVP_camellia_128_cfb8()
  • EVP_camellia_192_cfb8()
  • EVP_camellia_256_cfb8()
  • EVP_camellia_128_cfb128()
  • EVP_camellia_192_cfb128()
  • EVP_camellia_256_cfb128()
  • EVP_camellia_128_ctr()
  • EVP_camellia_192_ctr()
  • EVP_camellia_256_ctr()
  • EVP_camellia_128_ecb()
  • EVP_camellia_192_ecb()
  • EVP_camellia_256_ecb()
  • EVP_camellia_128_ofb()
  • EVP_camellia_192_ofb()
  • EVP_camellia_256_ofb()

and what do they all do? Camellia 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
  • OFB ⭐

like, pick your key size, pick your mode, and go be iconic. that's the whole vibe ✨

🧚 NOTES 🧚

okay listen up bestie, this part is important — developers 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-CAMELLIA(7) instead. see "Performance" in crypto(7) for further information.

fr fr, if you're spamming these calls in a loop you're gonna have a bad time. fetch it once, slay all day 💅

🍓 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. so yeah, you get a whole struct back, no cap 🫶
