EVP_CIPHER-DES(7ossl)

📦 version 3.5.0, in opensuse-leap 16.0

💅 EVP_CIPHER-DES — the DES era, explained ✨

okay so bestie, this is the EVP_CIPHER-DES page from the OpenSSL manual set (that's the 7ossl section, iykyk 🫶), and it's literally just the whole DES situation for EVP_CIPHER. Buckle up 🎀

🌸 NAME 🌸

EVP_CIPHER-DES — the DES EVP_CIPHER implementations. That's it, that's the vibe 💖

✨ DESCRIPTION ✨

It's support for DES symmetric encryption using the EVP_CIPHER API. Slay, but make it 1977 🦋

🧚 Algorithm Names 🧚

Not all DES is available everywhere, bestie — it depends on which provider you're running. Here's the tea ☕

The following algorithms are available in the FIPS provider as well as the default provider:

  • "DES-EDE3-ECB" or "DES-EDE3"
  • "DES-EDE3-CBC" or "DES3"

The following algorithms are available in the default provider, but not the FIPS provider:

  • "DES-EDE3-CFB8" and "DES-EDE3-CFB1"
  • "DES-EDE-ECB" or "DES-EDE"
  • "DES-EDE-CBC"
  • "DES-EDE-OFB"
  • "DES-EDE-CFB"
  • "DES3-WRAP"

The following algorithms are available in the legacy provider:

  • "DES-ECB"
  • "DES-CBC"
  • "DES-OFB"
  • "DES-CFB", "DES-CFB1" and "DES-CFB8"
  • "DESX-CBC"
💀 not the legacy provider... if your cipher lives in there it's giving "retro on purpose", and you need to actually load that provider. No cap.

🎀 Parameters 🎀

This implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3) — including "encrypt-check" and "fips-indicator". That's the whole menu, periodt 💅
