通过HTTP将字节数组从Android发送到服务器端PHP脚本

Question

I have an Android application which use AES encryption to encrypt a password. I have a key in my app and I generate a random IV for each encryption, and I will use this IV to decrypt the password in a php file.

In the android application, the IV is a byte[] and I don't know how to send it via http request.

I think I have to encode it because the byte[] generated is not convertible in a String to send it easily but I don't know how.

I was thinking to send it with a ByteArrayEntity but I can't give a name to this POST parameter so I can't receive it from my PHP file.

If you have any idea, can you help me please ?

Thanks in advance

Use base64 encoding. Both android and java provide mechanisms to encode and decode bae64 strings into usable formats for their respective encryption mechanisms.
