💖 EVP_MD-SHA2 — the SHA2 glow-up, explained

okay so bestie, this is a page from the OpenSSL manual set (7ossl section, the "miscellaneous / conventions" girlies) and it's literally all about The SHA2 EVP_MD implementation. No cap.

✨ NAME ✨

EVP_MD-SHA2 — the SHA2 EVP_MD implementation. that's the whole name, she's concise 💅

🌸 DESCRIPTION 🌸

So basically: this is the support for computing SHA2 digests through the EVP_MD API. That's it. That's the vibe check. 🦋

🎀 Identities 🎀

This implementation includes the following varieties — and they're grouped by which provider you can find them in, so pay attention bestie 👑

  • Available with the FIPS provider as well as the default provider:
    • SHA2-224 — Known names are "SHA2-224", "SHA-224" and "SHA224".
    • SHA2-256 — Known names are "SHA2-256", "SHA-256" and "SHA256".
    • SHA2-384 — Known names are "SHA2-384", "SHA-384" and "SHA384".
    • SHA2-512 — Known names are "SHA2-512", "SHA-512" and "SHA512".
  • Available with the default provider:
    • SHA2-256/192 — Known names are "SHA2-256/192", "SHA-256/192" and "SHA256-192".
    • SHA2-512/224 — Known names are "SHA2-512/224", "SHA-512/224" and "SHA512-224".
    • SHA2-512/256 — Known names are "SHA2-512/256", "SHA-512/256" and "SHA512-256".
ngl the naming situation is giving "three nicknames, one girl" — same digest, different aliases, so don't come for me when your code uses "SHA256" and someone else's uses "SHA2-256". they're the same, iykyk 😌

🧚 Gettable Parameters 🧚

This implementation supports the common gettable parameters described in EVP_MD-common(7). that's the lore, go read the sister page 📖✨
