使用frida hook android APP中的encrypt函数，并将函数该中的SM4方法的paramData参数发送给python处理，python处理后再返回到内存中执行后续代码，你能提供相应的代码吗

这个问题涉及的代码比较多，我尽可能提供完整的代码实现。

首先，需要使用Frida来Hook目标APP中的encrypt函数并将参数发送给Python处理。以下是Frida脚本的代码示例：

// Hook encrypt function
Interceptor.attach(Module.findExportByName("libnative-lib.so", "encrypt"), {
    onEnter: function(args) {
        // args[0] is JNIEnv pointer, args[1] is jobject instance, args[2] is jbyteArray paramData
        var paramData = Java.array('byte', Memory.readByteArray(args[2], args[3].toInt32()));
        // Send paramData to Python script for further processing
        send(paramData);
    }
});

接下来，需要编写Python脚本来处理收到的参数并返回处理结果。以下是Python脚本的代码示例：

import frida
import binascii

# Connect to the target device and start the target app
device = frida.get_usb_device()
pid = device.spawn(["com.example.app"])
session = device.attach(pid)
device.resume(pid)

# Attach to the target app and load the Frida script
script = session.create_script(open("hook.js", "r").read())
script.load()

# Receive paramData from the target app and process it
def on_message(message, data):
    if message['type'] == 'send':
        paramData = message['payload']
        # Process paramData here, for example, decrypt it with SM4
        result = sm4_decrypt(paramData)
        # Send the result back to the target app
        session.post_message(result)

# Register the message handler
script.on('message', on_message)

# Wait for the script to finish
raw_input()

最后，在Frida脚本中添加处理结果的代码。以下是完整的Frida脚本的代码示例：

// Hook encrypt function
Interceptor.attach(Module.findExportByName("libnative-lib.so", "encrypt"), {
    onEnter: function(args) {
        // args[0] is JNIEnv pointer, args[1] is jobject instance, args[2] is jbyteArray paramData
        var paramData = Java.array('byte', Memory.readByteArray(args[2], args[3].toInt32()));
        // Send paramData to Python script for further processing
        send(paramData);
    }
});

// Receive the result from Python script and replace the return value of encrypt function
rpc.exports = {
    setResult: function(result) {
        // Convert the result to a byte array
        var resultByteArray = Java.array('byte', result);
        // Replace the return value of encrypt function with the result
        Memory.writeByteArray(this.context.x0, resultByteArray);
    }
};

这样，当Python脚本处理完参数后，会将结果发送回到Frida脚本，Frida脚本再将结果替换到encrypt函数的返回值中。
