str2hex - Data formats convertion utility.

A data conversion utility that convert files or strings to different representations of Hexadecimal number encodings, as well as Base64, and even MD5.

It was one of my first C program written more than 10 years ago, so don't judge strictly :)

Building

It is as simple as:

% make
