💖 EVP_CIPHER-RC2 💖

okay so this is the OpenSSL manual page EVP_CIPHER-RC2(7ossl) bestie, and it's literally all about the RC2 EVP_CIPHER implementations — short page, but it ate ✨

🌸 NAME 🌸

EVP_CIPHER-RC2 — the RC2 EVP_CIPHER implementations, no cap 💅

🦋 DESCRIPTION 🦋

So basically: this is the support for RC2 symmetric encryption using the EVP_CIPHER API. That's the whole vibe. 🫶

🎀 Algorithm Names 🎀

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

  • "RC2-CBC", "RC2" or "RC2-128"
  • "RC2-40-CBC" or "RC2-40"
  • "RC2-64-CBC" or "RC2-64"
  • "RC2-ECB"
  • "RC2-CFB"
  • "RC2-OFB"

like, yes, some of them have multiple aliases — they're the same algorithm, it's giving "I go by two names" main character energy 👑

🧚 Parameters 🧚

This implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3). That's it, that's the sentence — go read that one for the deets 🔥
