LIBKECCAK_BEHEX_LOWER(3)

okay so welcome to libkeccak_behex_lower(3) from the Library Functions Manual — the LIBKECCAK page is here to make lower-case hex make sense 💅✨

🌸 NAME 🌸

libkeccak_behex_lower — converts a binary hashsum to lower case hexadecimal. That’s the whole assignment, bestie 🎀

🦋 SYNOPSIS 🦋

#include <libkeccak.h>

void libkeccak_behex_lower(char *restrict output, const void *restrict hashsum, size_t n);

Link with -lkeccak.

💖 DESCRIPTION 💖

okay so libkeccak_behex_lower() takes the binary hashsum stored in hashsum, turns it into lowercase hexadecimal, and puts that hexadecimal representation into output. slay 💅

output will be terminated by a NUL-character. yes, the classic little terminator icon.

The n parameter specifies the number of bytes the binary hashsum is comprised. and the allocation math is not optional, bestie: output needs an allocation size of (2 * n + 1) ✨

don’t skimp on that (2 * n + 1) allocation, fr fr — the page says output needs it 🫶

🌈 RETURN VALUES 🌈

The page says: “The libkeccak_behex_lower() function does return any value.” Translation: don’t go looking for a return value to catch — it’s not that kind of function, periodt 😭

⭐ ERRORS ⭐

libkeccak_behex_lower() cannot fail. iconic. no error era, just success energy 💀✨
