ppencode

[dankogai]

Takesako-san has set the new way to (?:de)?obfuscate your script -- or any file via ppencode

Feed the to your camel and see what happens.

Actually this is a generalized version of Fun with Reserved Keywords.

Enjoy!

Three years ago, the inimitable mtve produced at least three different versions of these type of obfuscators:

• Yet Another Obfuscation Engine
• Yet Another**2 Obfuscation Engine
• Yet Another**3 Obfuscation Engine

You think so? Not quite.

0. only encodes codes. ppencode can encode any given sequence of bytes.
1. contains binary | and ^.
2. q zz ze ? zz and ze are not reserved.

in addition to ppencode itself, the package comes with gen_ppencode which does generate ppencode -- the resuiting ppencode might be different for each invocation thereof.

Feed the to your camel and see what happens.

Can't take log of 0 at - line 2.

You could change log to another function that doesn't choke on $_, or you could remove the xor after it so that it applies to the return value from print.

Heck. 1st try (the last one being the 0th)

hex cos xor print chr oct ord q open do xor print chr ord qw q uc q xor print chr ord qw q sin q xor print chr ord q gt log xor print chr ord q q q xor print chr oct ord q ne sin xor print chr ord qw q no q xor print chr ord qq pop xor print chr ord q stat s xor print chr ord q chr lc xor print chr ord q ge log xor print chr ord q qr q xor print chr ord q q eq xor print chr oct ord q qx q xor print chr ord q ne sin xor print chr ord q or no xor print chr ord qw q lc q xor print chr ord qq q q xor print chr oct ord qw q ne q xor print chr ord q each le xor print chr ord q oct no xor print chr ord qw q kill q xor print chr ord q ne sin xor print chr ord q qr q

I'll tell him about the 'log' bug. Anyway, please do try the URL mentioned. It does give you different codes randomly.
