Umm, you just stored the number of bytes read in 'dataRead'. Why are you
passing 'readBuffer' to strlen? The 'readBuffer' contains the array of bytes
read from the link, it is not a C-style string. Only a C-style string may be
passed to 'strlen'.

You are passing characters one-at-a-time to your decryption function.
Depending on exactly what this function does, this may indicate that you are
not getting the security you expected.

Your 'decrypt' function takes as input a single character and returns a
C-style string?
Either your code is *truly* weird, or you have some basic misunderstandings
about C-style strings.
