PHPSeclib使用心得:RSA加密和AES加密

1.RSA

新建金鑰對:

$rsa = new RSA();
$result = $rsa->createKey();
echo $result["privatekey"]    //私鑰
$result["publickey"]    //公鑰

加密:

$rsa = new RSA();
$rsa->loadKey($key);

$rsa->setEncryptionMode(RSA::ENCRYPTION_NONE);    //選擇加密的模式,可選模式參考官方文件

echo base64_encode($rsa->encrypt($msg));    //需要對結果進行base64轉碼,否則為亂碼

解密:

$rsa = new RSA();
$rsa->loadKey($key);

$rsa->setEncryptionMode(RSA::ENCRYPTION_PKCS1);

echo $rsa->decrypt(base64_decode($msg));    //同理,解碼時,需要先進行base64解碼

目前筆者測試能和PHPSeclib的 RSA配合的javascript包為: https://github.com/rzcoder/node-rsa

2.AES

加密:

$aes = new AES(MCRYPT_MODE_ECB);
$aes->setKey(self::KEY);
$aes->setIV(self::VECTOR);
echo base64_encode($aes->encrypt($msg));

解密:

$aes = new AES(MCRYPT_MODE_ECB);
$aes->setKey(self::KEY);
$aes->setIV(self::VECTOR);
echo $aes->decrypt(base64_decode($msg));
