# Convert hex to base64

The string:

    49276d206b696c6c696e6720796f757220627261696e206c696b65206120706f69736f6e6f7573206d757368726f6f6d

Should produce:

    SSdtIGtpbGxpbmcgeW91ciBicmFpbiBsaWtlIGEgcG9pc29ub3VzIG11c2hyb29t

So go ahead and make that happen. You'll need to use this code for the
rest of the exercises.

## Cryptopals Rule

Always operate on raw bytes, never on encoded strings. Only use hex
and base64 for pretty-printing.
