💅 EVP_CIPHER-CAST 💅

okay so this is a page from the OpenSSL manual — EVP_CIPHER-CAST(7ossl) — and it's literally all about the CAST family of ciphers living inside the EVP_CIPHER API. bestie, let's get into it 🎀

✨ NAME ✨

EVP_CIPHER-CAST — the CAST EVP_CIPHER implementations. that's the whole vibe. no cap. 🦋

🌸 DESCRIPTION 🌸

so basically: support for CAST symmetric encryption using the EVP_CIPHER API. that's it, that's the tea 💖

🧚 Algorithm Names 🧚

the following algorithms are available in the legacy provider — key detail, don't forget it, iykyk 👑

  • "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 line is in that exact order — not me being chaotic, that's just how it's written. leave it. 💅)

🎀 Parameters 🎀

this implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3). so if you wanna know what knobs you can turn, that's your page, bestie 🫶
