EVP_CIPHER-CAST(7ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 EVP_CIPHER-CAST (that's the 7ossl manual, bestie)

Okay so listen — this page is literally all about CAST symmetric encryption via the EVP_CIPHER API. That's it, that's the vibe. Let's get into it ✨

🌸 NAME 🌸

EVP_CIPHER-CAST — the CAST EVP_CIPHER implementations, aka the whole cast of characters for CAST ciphers in EVP 🎀

✨ DESCRIPTION ✨

So basically: there's support for CAST symmetric encryption, and it all runs through the EVP_CIPHER API. That's the entire tea ☕

👑 Algorithm Names 👑

Heads up bestie — these algorithms live in the legacy provider, not the default one, iykyk. The following algorithms are available:

  • "CAST-128-CBC", "CAST-192-CBC" and "CAST-256-CBC"
  • "CAST-128-CFB", "CAST-192-CFB", "CAST-256-CFB"
  • "CAST-128-ECB", "CAST-192-ECB" and "CAST-256-ECB"
  • "CAST-192-OFB", "CAST-128-OFB" and "CAST-256-OFB"

(Yes, the OFB list is in that order in the source. Not me fixing it, that's just what it says 💅)

🦋 Parameters 🦋

This implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3). Go read that one for the full parameter lore 📖
