PHP for switching between Bin2Hex and Hex2bin via AES encryption/decryption

This article mainly for you to share a PHP, such as through the AES encryption/decryption to achieve the switch between Bin2Hex and Hex2bin, has a very good reference value, I hope to help you. Follow the small series together to see it.

<?php/** * Request Data via AES Encryption * * @param array $query * @return String *                    /function Aesencryptrequest ($encryptKey, $query) {return $this->encrypt_pass ($query, $encryptKey); }//Cryptographic function Encrypt_pass ($input, $key) {$size = Mcrypt_get_block_size (MC             rypt_rijndael_128, MCRYPT_MODE_ECB);             $input = Pkcs5_pad ($input, $size);            $TD = Mcrypt_module_open (mcrypt_rijndael_128, ', MCRYPT_MODE_ECB, ');            $iv = ' 0102030405060708 ';            Mcrypt_generic_init ($TD, $key, $IV);            $data = Mcrypt_generic ($TD, $input);            Mcrypt_generic_deinit ($TD);             Mcrypt_module_close ($TD);            $data = Bin2Hex ($data);        return $data;             }//Fill function Pkcs5_pad ($text, $blocksize) {$pad = $blocksize-(strlen ($text)% $blocksize); Return $text.        Str_repeat (Chr ($pad), $pad);    }        /** * Decrypt request Data via AES * * @param array $query * @return String */func                    tion Aesdecryptresponse ($encryptKey, $data) {return $this->decrypt_pass ($data, $encryptKey);            }//Decryption function Decrypt_pass ($SSTR, $sKey) {$iv = ' 0102030405060708 ';                $decrypted = Mcrypt_decrypt (mcrypt_rijndael_128, $sKey, Hex2bin ($SSTR),            MCRYPT_MODE_ECB, $IV);            $dec _s = strlen ($decrypted);            $padding = Ord ($decrypted [$dec _s-1]);            $decrypted = substr ($decrypted, 0,-$padding);        return $decrypted; }
