PyKryptor - v1.6

"v1.5 don't work..."

Oh. Anyways don't use v1.5!! Since the .exe just fails to run; 1.6 has everything that 1.5 has too.

.zip password

The new password for the .zip file is PyKx, the stable Windows based .exe is in there with the source code and documentation for manual compiling.

Why password a .zip?

Not because I'm hiding something but rather because Google Drive keeps taking down my damn file since it keeps on getting flagged by their nonexistent AV.
