Hello,

I'm trying to use libgcrypt to generate a hash. I'm pretty new to programming so I'm just testing out the library.

This is the code I've written:

#include <stdio.h>
#include <stdlib.h>
#include <gcrypt.h>
#include <stdbool.h>

int main(void)
{
    const char* gcrypt_version = gcry_check_version(NULL);
    if (!gcrypt_version)
    {
        fprintf(stderr, "ERROR: libgcrypt was unable to initialize\n");
        exit(2);
    }
    printf("Gcrypt Version: %s\n", gcrypt_version);

    gcry_control(GCRYCTL_DISABLE_SECMEM, 0);
    gcry_control(GCRYCTL_INITIALIZATION_FINISHED, 0);

    if (!gcry_control(GCRYCTL_INITIALIZATION_FINISHED_P))
    {
        fprintf(stderr, "ERROR: libgcrypt has not been initialized\n");
        abort();
    }


    char* text = "hello\n";
    char hash_storage[200] = {0};
    gcry_md_hash_buffer(GCRY_MD_MD5, hash_storage, text, strlen(text));
    printf("%s\n", hash_storage);

    return 0;

}

As you can see I'm just trying to test out this function. Everything runs but at the end the printf prints out jibberish which I'm unable to interpret. How is the hash digest encoded?

Yours faithfully,
megamind6155.
