Decoder for JavaCrypt encoder
It is a very nice and fun encryptor, using consistency checks and attempting escape from the debugger: you might want to try unpacking it yourself. There are two actual samples in the "samples" folder, in case you want to try them out yourself.
The "v1" is an older version of encryption, e.g it has problems running under Chrome — those are later fixed in the v2 by the unknown authors of the unknown tool.
require_once('js.decrypt.javacrypt.php'); $decrypted = decrypt_javacrypt($encrypted);
The function will just return false if it can't determine packer — or if the unpacked results seem way off.
You may run the script from the command-line using the php interpreter:
php js.decrypt.javacrypt.php encrypted_file.js
