💖 KNET_GET_CRYPTO_LIST(3) — the Kronosnet Programmer's Manual one, bestie 💖

okay so. hi. welcome to knet_get_crypto_list(3), a page from the Kronosnet Programmer's Manual, and honestly? she's a whole vibe. let's get into it 🫶

✨ NAME ✨

knet_get_crypto_list — Get a list of supported crypto libraries.

like, all of them. the roster. the lineup. the crypto girlies 💅

🌸 SYNOPSIS 🌸

#include <libknet.h>

int knet_get_crypto_list(
    struct knet_crypto_info   *crypto_list,
    size_t                    *crypto_list_entries
);

look at her. two args. no drama. ✨

🦋 DESCRIPTION 🦋

knet_get_crypto_list

  • crypto_list — array of struct knet_crypto_info *. If it's NULL then only the number of structs is returned in crypto_list_entries, which lets you allocate sufficient space yourself first. bestie, this is the "let me peek at the menu before I order" move 🍓 libknet does not allow more than 256 crypto methods at the moment. it is safe to allocate 256 structs to avoid calling knet_get_crypto_list twice.
  • crypto_list_entries — returns the number of structs in crypto_list.

so like, you either ask twice (once for the count, once for the goods) or you just send it with 256 and call it once. main character efficiency, no cap 😌

🎀 STRUCTURES 🎀

Structure returned from get_crypto_list() containing information about the installed cryptographic systems.

struct knet_crypto_info {
    const char   *name;        /* Name of the crypto library/ openssl, nss,etc .. */
    uint8_t       properties;  /* Properties - currently unused */
    char          pad[256];    /* Currently unused padding */
};

so name is the actual tea — openssl, nss, etc. properties is currently unused (she's just there, being cute, contributing nothing 🙈) and pad[256] is currently unused padding, also just vibing. iconic honestly.

👑 RETURN VALUE 👑

knet_get_crypto_list returns 0 on success, -1 on error and errno is set.

not to be dramatic but if you see that -1, check errno. she's always trying to tell you something 💀
