EVP_MD-SHA2(7ossl)

📦 version 3.5.0, in opensuse-leap 16.0

✨ EVP_MD-SHA2 ✨

okay so bestie, welcome to the EVP_MD-SHA2 page — it's page 7ossl in the OpenSSL manual set, and it's literally all about the SHA2 EVP_MD implementation 💅

🌸 NAME 🌸

EVP_MD-SHA2 — the SHA2 EVP_MD implementation. that's it, that's the whole name, she's lowkey self-explanatory 🎀

🦋 DESCRIPTION 🦋

so this is your support for computing SHA2 digests through the EVP_MD API ✨ like, that's the whole vibe check of this page.

💖 Identities 💖

this implementation ships with the following varieties — think of them as the whole squad 👑

  • available with the FIPS provider as well as the default provider:
    • SHA2-224 — known names are "SHA2-224", "SHA-224" and "SHA224". three aliases, one icon 💫
    • SHA2-256 — known names are "SHA2-256", "SHA-256" and "SHA256". yes she goes by all three, main character energy fr fr 🌟
    • SHA2-384 — known names are "SHA2-384", "SHA-384" and "SHA384". no cap 🫶
    • SHA2-512 — known names are "SHA2-512", "SHA-512" and "SHA512". iconic, periodt 🔥
  • available with the default provider (these ones are default-provider-only, iykyk):
    • SHA2-256/192 — known names are "SHA2-256/192", "SHA-256/192" and "SHA256-192". ok the third one drops the slash, that's just her thing 🙈
    • SHA2-512/224 — known names are "SHA2-512/224", "SHA-512/224" and "SHA512-224". slay 🌈
    • SHA2-512/256 — known names are "SHA2-512/256", "SHA-512/256" and "SHA512-256". the way that these names are all consistent... obsessed 💜
ngl, watch the name spellings — they're not all the same pattern. SHA2-256/192 keeps its slash in all three aliases, but SHA2-512/224 and SHA2-512/256 go slashless in the third form. copy them exactly, bestie, don't get cute with it 💀

🧚 Gettable Parameters 🧚

this implementation supports the common gettable parameters described over in EVP_MD-common(7) ⭐ — so if you need the deets on those, that's the page to go read. 🍓
