So basically bestie, this is the support for symmetric encryption with IDEA, and you drive it through the EVP_CIPHER API. that's the vibe. that's the whole vibe. 💅

🦋 Algorithm Names 🦋

Here are the algorithms you can get, and heads up — they're available in the legacy provider:

  • "IDEA-ECB"
  • "IDEA-CBC"
  • "IDEA-OFB" or "IDEA-OFB64"
  • "IDEA-CFB" or "IDEA-CFB64"
bestie the "legacy provider" part is important, don't skip it — these aren't just hanging out in the default setup, iykyk 👑
