"Go" PHP Android iOS compatible AES encryption algorithm

App Project user password transmission has been no use of HTTPS, considering that the user's privacy is temporarily encrypted with AES, and later can be used for mobile phone and server-side encryption interaction.

PHP free version of the Phpaes project, the phone-side decoding all kinds of wrong.

Finally find the PHP ANDROID IOS, Mutual decryption normal AES encryption algorithm code.
