php的加密解密

  加密：$content = urlencode(openssl_encrypt('data','AES-256-ECB',$key));  不需要urlencode()方法

  解密: $content = openssl_decrypt('data','AES-256-ECB',$key);  

$key = 'f4e529a3eda54d8eb8eb1b1b9041c9ec';
//生成注册的密钥
//$ss = openssl_encrypt(json_encode(array('traceNo'=>'510000000010000000003','idCard'=>'511028196411211XXX','name'=>'XXX','signupTime'=>date('Y-m-d H:i:s',1510799759),'requestNo'=>'510000000010000000003'),JSON_UNESCAPED_UNICODE),'AES-256-ECB',$key);


//echo $ss;
//echo openssl_decrypt('ebA51B9hBBbqoI1fCScJsncM2LiHE5E18RjkaRtp0EkXZhmIbfoVvhEj5st282+DfTNpTUz5HFeAQ3reKUHVKbMGnM9zwwdQON704JrMmY9GntRvjdUa/hnV5xZcI0m4ZZCkMyyjWMfagAzQvsQ6zzfY2L6PjBw42PtD5MeXh2UXGTTtwAbzdiWZMyWFW7zFYeH6WdgbkHUGxXNfznXIBA==','AES-256-ECB',$key);
