EVP_CAMELLIA_128_ECB(3ossl)

💖 EVP_CAMELLIA_128_ECB — the Camellia cipher glow-up, but for EVP 💖

okay bestie, so this page is from the OpenSSL manual, section 3ossl (that's the library-functions section, iykyk), and it's all about the Camellia cipher functions you can pull into EVP. Yes, there's a lot of them. No, we are not skipping any. Sit down, hydrate, let's go. 🫶

✨ 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

…and collectively? They're the EVP Camellia cipher. 🌸 That's the whole vibe of this page: a whole girl-group of cipher functions, all named EVP_camellia_*, all here for you.

---

✨ SYNOPSIS ✨

okay so the include is giving:

#include <openssl/evp.h>

const EVP_CIPHER *EVP_ciphername(void)

and like — EVP_ciphername is a placeholder, bestie, not a real function you can call. 💀 It stands in for any of the described cipher functions, like EVP_camellia_128_cbc. So every time you see EVP_ciphername, mentally swap in whichever Camellia girlie you actually want. 🎀

---

✨ DESCRIPTION ✨

It's the Camellia encryption algorithm, wired up for EVP. That's the tea. 🍓

Now the full lineup, no cap — every single one of these:

• 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 all of them do is: 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

that's the whole menu. 3 key sizes × 7 modes = your 24 functions. math ate, periodt. 💅

✨ NOTES ✨

okay this is the part where I grab you by the shoulders, bestie. 👑

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.

so like — if you're calling these over and over, that's lowkey a performance L. 😭 The glow-up move is EVP_CIPHER_fetch(3) paired with EVP_CIPHER-CAMELLIA(7). For the full breakdown, go read the "Performance" section in crypto(7). fr fr, go read it.

---

✨ RETURN VALUES ✨

Every one of these functions hands you back an EVP_CIPHER structure, and that structure holds the implementation of the symmetric cipher. 🎁 If you wanna know what's inside that EVP_CIPHER struct — the anatomy, the details, all of it — go look at EVP_CIPHER_meth_new(3). That's where the lore lives. 📖

and that's the page, bestie!! 🦋💜 this little beauty dropped in 3.5.9, dated 2026-09-29, and it lives in the OpenSSL manual as EVP_CAMELLIA_128_ECB(3ossl). go encrypt something iconic, you main character. 💅✨🌈
