💖 EVP_CIPHER-DES — the DES EVP_CIPHER implementations 💖

okay bestie, so this is EVP_CIPHER-DES, from the 7SSL manual set, courtesy of OpenSSL. it's the glow-up doc for the DES family of ciphers — the OGs of symmetric crypto, and yes we still talk about them. 🫶

✨ NAME ✨

EVP_CIPHER-DES — literally just: the DES EVP_CIPHER implementations. that's the whole name section, she's short and she knows it. 💅

🌸 DESCRIPTION 🌸

Support for DES symmetric encryption using the EVP_CIPHER API. that's it, that's the vibe. you plug a DES-style algorithm name into the EVP_CIPHER machinery and she runs it for you. 🦋

🔥 Algorithm Names 🔥

not all DES algorithms live in the same place, and this is the part that trips people up, so pay attention bestie:

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"
💀 no cap: which provider you've got loaded decides which of these names you can actually use. if you can't find one of the legacy girls, that's a provider situation, not a you situation.

🎀 Parameters 🎀

This implementation supports the parameters described in "PARAMETERS" in EVP_EncryptInit(3), including "encrypt-check" and "fips-indicator". so if you want the full deets on those, go read that page, we're just repping the whole parameter menu here, iconically. ✨

that's the whole page bestie, go forth and encrypt (responsibly, with the right provider loaded 🙈). version 4.0.3, dated 2026-09-29 — mwah, slay, periodt. 💜
