Example code for PHP docking Java's aes/ecb/pkcs5padding encryption method

Because of the project needs, and an insurance company docking call API, my company is the PHP background, the insurance company is Java background, the middle of the data transmission will not be able to encrypt, decrypt, the current encrypted AES comparison recommended.

In the process of docking, it is inevitable to turn over the mountains, the more water,

Here are the encryption instructions for my docking company:

Be sure to know their own encryption method, or a cryptographic mode of the ECB, CBC differences, the results are very different.

Attach the final code that can be used:

<?phpclass Security {public static function encrypt ($input, $key) {$size = Mcrypt_get_block_size (Mcrypt_rijndae    l_128, MCRYPT_MODE_ECB);    $input = Security::p kcs5_pad ($input, $size);    $TD = Mcrypt_module_open (mcrypt_rijndael_128, ', MCRYPT_MODE_ECB, ');    $iv = Mcrypt_create_iv (Mcrypt_enc_get_iv_size ($TD), Mcrypt_rand);    Mcrypt_generic_init ($TD, $key, $IV);    $data = Mcrypt_generic ($TD, $input);    Mcrypt_generic_deinit ($TD);    Mcrypt_module_close ($TD);    $data = Base64_encode ($data);    return $data;        } private static function Pkcs5_pad ($text, $blocksize) {$pad = $blocksize-(strlen ($text)% $blocksize); Return $text.    Str_repeat (Chr ($pad), $pad);        The public static function decrypt ($SSTR, $sKey) {$decrypted = Mcrypt_decrypt (mcrypt_rijndael_128,         $sKey, Base64_decode ($SSTR), MCRYPT_MODE_ECB);        $dec _s = strlen ($decrypted);        $padding = Ord ($decrypted [$dec _s-1]); $decrypted = suBSTR ($decrypted, 0,-$padding);    return $decrypted;  }}//$key = "1234567891234567";//$data = "Example"; $value = Security::encrypt ($data, $key);//echo "Encryption::". $value. ' <br/> ';//echo Security::d ecrypt ($value, $key);

In public functions called:

/** * Request Body Encryption * @param array $content Policyholder's information * @return string        */function Hetai_encrypt ($content) {//Scheme VII Print_r ("\ r \ n"); Vendor (' Encrypt.

Binary string to 16 binary, 16 binary string to binary:

/**     * String to hex     * @param string $string     * @return String     *    /function Strtohex ($string)    {        $ Hex= "";        for ($i =0; $i <strlen ($string); $i + +)            $hex. =dechex (Ord ($string [$i]));        $hex =strtoupper ($hex);        return $hex;    }         /**     * Hexadecimal to string     * 16 binary to 2 binary string         * @param hex $hex     * @return String *    /function Hextostr ( $hex)    {        $string = "";        for ($i =0; $i <strlen ($hex)-1; $i +=2)            $string. =CHR (Hexdec ($hex [$i]. $hex [$i +1]);        return  $string;    }

Attached to torture my three days of cryptographic function block, only for their own reminders, do not like to spray ~
