Decrypting LUA files - Android Q&A, Help & Troubleshooting

Hey
I'm trying to decrypt the LUA files.
I'm running the game on my phone
I run this script
Code:
#!/usr/bin/env python
import frida
import sys
package_name = "com.elex.nikkigp"
def get_messages_from_js(message, data):
if message['type'] == 'send':
print("[*] {0}".format(message['payload']))
else:
print(message)
jsc = """
var _address = Module.findExportByName( "libcocos2dcpp.so", "Z13xxtea_decryptPhjS_jPj");
if (null === _address)
throw 'xxtea_decrypt NOT FOUND';
Interceptor.attach (_address, {
onEnter: function (args) {
console.log("----------------BEGIN----------------");
console.log(hexdump(Memory.readByteArray(args[2], 12),{
offset: 0,
length: 12,
header: true,
ansi: true
}));
},
onLeave: function (retval) {
console.log("Decrypt:");
console.log(hexdump(Memory.readByteArray(retval, 16),{
offset: 0,
length: 16,
header: true,
ansi: true
}));
console.log("-----------------END-----------------");
}
});
"""
process = frida.get_usb_device().attach(package_name)
script = process.create_script(jsc)
script.on('message',get_messages_from_js)
script.load()
print("[*] Start Script")
sys.stdin.read()
Error xxtea_decrypt NOT FOUND
Although the xxtea_decrypt function in libcocos2dcpp yes.
