STRUCT SHA512_CTX(9)

✨ NAME ✨

okay so bestie, welcome to struct sha512_ctx(9) — this is from the Kernel API Manual, section 9, and it's literally the context for hashing a message with SHA-512. no cap, that's the whole vibe.

🦋 SYNOPSIS 🦋

the whole struct is right here, copy-pasted exactly because we do not mess with code:

struct sha512_ctx {
    struct __sha512_ctx ctx;
 };

🎀 Members 🎀

• ctx — private 🙈 that's it, that's the whole member. the manpage is not gonna elaborate, and honestly? iconic minimalism.

ngl this page is short and sweet — it's a wrapper struct, not a whole saga. but every crumb of info is here, periodt.

🌈 SEE ALSO 🌈

the kernel file ./include/crypto/sha2.h is like the group chat where all these live:

and that's the page, bestie 🫶 source/version is ./include/crypto, dated October 2026, and the page itself is struct sha512_ctx(9) — byeee 💅✨
