I'm trying to create a MD5 hash using "openssl/md5.h".  I'm either
missing something or am missing typecasting somewhere.

For an answer, I'm looking for what has to change in my code to get
the correct output.

--- BEGINNING OF CODE ---
unsigned char* input = (unsigned char*) strdup("thisIsATest");
cout << input << endl;
unsigned char buffer[1024];
MD5(input, 11, buffer);
cout << buffer << endl;
--- END OF CODE ---

prints out:
thisIsATest
<bunch of low and high ascii characters>

My understanding is that a MD5 hash should only use alpha-numerics. 
Why am I getting the high ascii?

I know the correct MD5 hash is: 791d8bf5f019659d15ce4fb04ad70316

I figured it out ...

At least for the function I'm using, buffer has to be looked at
character by character.  For the output to be in the form I wanted,
the hexidecimal contents of the character need to be printed -- rather
than printing the character itself (which does an ASCII table lookup.)

For example, the first character printing out was a "y".  The value of
that character was hexidecimal 79, however by just printing it, a "y"
was printed because hexidecimal 79 is "y" in the ASCII table.
