✨ shishi_authenticator_add_cksum_type ✨

okay bestie, sit down, we're doing a shishi manpage and it's from the shishi manual, version 1.0.3. it's a lil API function and honestly? it's giving "small but mighty". 💖

🌸 NAME 🌸

shishi_authenticator_add_cksum_type — literally an API function, that's the whole name, no notes 💅

🎀 SYNOPSIS 🎀

#include <shishi.h>

int shishi_authenticator_add_cksum_type(Shishi * handle, Shishi_asn1
authenticator, Shishi_key * key, int keyusage, int cksumtype, char *
data, size_t datalen);

🦋 ARGUMENTS 🦋

  • Shishi * handle — the shishi handle, the one you got from shishi_init(). your main character, fr fr.
  • Shishi_asn1 authenticator — the authenticator, as allocated by shishi_authenticator(). yes queen, that exact one.
  • Shishi_key * key — the key you're using for encryption. 🔐
  • int keyusage — the cryptographic key usage value that gets used in the encryption. yes it matters, no you can't skip it.
  • int cksumtype — the checksum type to calculate the checksum with. (the original says "checksum to type to calculate checksum" and honestly? we love a messy icon. it means: which checksum type, bestie.)
  • char * data — the input array holding the data you want the checksum calculated on.
  • size_t datalen — the size of that input array with the data you want the checksum calculated on. the vibes must be sized correctly. 📏

💜 DESCRIPTION 💜

so basically: you calculate a checksum for the data, and then you store it in the authenticator. that's the whole plot. no cap. ✨

🌈 RETURN VALUE 🌈

Returns SHISHI_OK iff successful. that's it. SHISHI_OK = slay, anything else = we do not talk about it 😭

🔥 REPORTING BUGS 🔥

found a bug? do NOT suffer in silence, bestie, report it to <bug-shishi@gnu.org>.
