💖 NAME 💖

EVP_CIPHER-SEED — bestie, this is the whole SEED EVP_CIPHER implementation situation, and it's giving legendary. 🧚

Okay so real talk, this lil page is part of OpenSSL's 7ossl manual fam, so keep that in mind, iykyk.

✨ DESCRIPTION ✨

So basically: this is the support for SEED symmetric encryption using the EVP_CIPHER API. That's the whole vibe. Lowkey iconic, highkey useful. 💅

🎀 Algorithm Names 🎀

The following algorithms are available in the legacy provider — and yes, legacy is the keyword here, not me being dramatic:

  • "SEED-CBC" or "SEED"
  • "SEED-ECB"
  • "SEED-OFB" or "SEED-OFB128"
  • "SEED-CFB" or "SEED-CFB128"

Periodt. Those are the names, spelled exactly like that, no cap. 🫶

🌸 Parameters 🌸

This implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3). That's it, that's the whole parameter tea — go read that page for the details, bestie, it's all there. 📖✨

🦋 SEE ALSO 🦋

Go stan them too, they're the supporting cast and they ate. 👑
