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:

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?
That jibberish is almost certainly a binary MD5 digest of "hello\n".
Try piping the output of your program through "hexdump -C" and compare
the last bytes to the output of "echo hello | md5sum" at a shell prompt.
As for how to use this, try writing a simple routine to dump the hash
value as hexadecimal instead of trying to print it as a string.
