💖 EVP_CIPHER-RC4 💖

okay bestie, listen — you know how there's a whole little manual page for this thing called EVP_CIPHER-RC4? yeah. it lives in the 7SSL section of the OpenSSL docs. this is it. pull up a chair, grab a matcha, let's go 🍓

✨ NAME ✨

EVP_CIPHER-RC4 — it's giving "the RC4 EVP_CIPHER implementations" ✨ no cap, that's literally what this page is about.

🌸 DESCRIPTION 🌸

So basically: this is all about support for RC4 symmetric encryption using the EVP_CIPHER API. that's the whole vibe. symmetric, RC4, through EVP_CIPHER. iconic behaviour tbh 👑

🎀 Algorithm Names 🎀

These algorithms? they're available in the legacy provider. (yes, legacy. we'll get to that vibe. keep reading.)

  • "RC4"
  • "RC4-40"
  • "RC4-HMAC-MD5"

three of them. a whole little trio. the way that they all just show up in the legacy provider and nowhere else 😭

💜 Parameters 💜

This implementation supports the parameters described in "PARAMETERS" over in EVP_EncryptInit(3). that's where the parameter lore lives, go check it out, i'm not repeating it here, it said what it said 🫶

🦋 SEE ALSO 🦋

like obviously the legacy provider one is there. it's giving "read the room" 🌈
