💖 libssh2_session_hostkey(3) 💖

okay so bestie, this one lives in the libssh2 manual, and it's genuinely one of the most useful little gremlins in the whole library. let's get into it 🫶

✨ NAME ✨

libssh2_session_hostkey — get the remote key 🔑

✨ SYNOPSIS ✨

#include <libssh2.h>

const char *
libssh2_session_hostkey(LIBSSH2_SESSION *session,
                        size_t *len, int *type);

✨ DESCRIPTION ✨

so basically 💅 this function hands you back a pointer to the current host key, and the value that len points to gets filled in with the length of the key. two-for-one, we love to see it ✨

and type? yeah that one points to the type of hostkey, and it's gonna be one of these three, no cap:

  • LIBSSH2_HOSTKEY_TYPE_RSA
  • LIBSSH2_HOSTKEY_TYPE_DSS — deprecated 🫠 like, it's still listed, but consider this your soft launch warning
  • LIBSSH2_HOSTKEY_TYPE_UNKNOWN
it's giving "three options only," and honestly? that's the whole list. periodt. 💀

✨ RETURN VALUE ✨

a pointer 💖 … or NULL if something went wrong 😭 (the villain era of return values).
