我正在尝试在 phpseclib 中使用 RSA 实现，我认为在函数中执行一次代码并重新使用该函数会更容易。当我尝试向代码发送短信时，我收到一条错误消息“解密错误”测试也让我意识到每次代码运行时密文都是不同的，所以我显然在那里做错了！
函数的代码是：
require_once "Crypt/RSA.php";
require_once "Crypt/AES.php";
//Function for encrypting with RSA
function rsa_encrypt($string, $public_key)
{
//Create an instance of the RSA cypher and load the key into it
$cipher = new Crypt_RSA();
$cipher->loadKey($public_key);
//Set the encryption mode
$cipher->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
//Return the encrypted version
return base64_encode($cipher->encrypt($string));
}
//Function for decrypting with RSA
function rsa_decrypt($string, $private_key)
{
//Create an instance of the RSA cypher and load the key into it
$cipher = new Crypt_RSA();
$cipher->loadKey($private_key);
//Set the encryption mode
$cipher->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
//Return the decrypted version
return $cipher->decrypt($string);
}
我尝试使用以下方法对其进行测试：（密钥仅用于测试，这就是其硬编码的原因）。正是在这里，每次运行代码时，$ciphertext 的值每次都会改变
//Private key
$private_key = "-----BEGIN RSA PRIVATE KEY----- MIICXAIBAAKBgQCU+1bLfPmcY7qrF/dTbAtuJlv4R/FVc1WEH9HKU0jQjX/n/db9vz/x0i3te/bK LNEcwUhBu+PWPnOt/qVURG9BUT6RsCRFUn0CyGiUKoy45o9K/mJAHmbrNtrUB6ckrYLF75Y50nUN sBVHUDw8yQymmiOBT1gc/KM5s1xTz44LMwIDAQABAoGAGsiMtAyFu23ac0PdvOuhqm3O/vXAF0Ki zxwBVURfxM6LfiOOcRPe5RSKGTW+Cl7AQVEmMlsa/LtBhLhQ9LNQ5L/4oTmRhCGiZZEmccAdjKsx yMeaxkp+ZHvMxMKQNDgYg1CXqrCrpwwUuMUlA26tfxZ3xSFtFyDTaV9mgDQ1IGECQQCkX9Tum7D1 vQTwbhbYnu7eC4eUOaZeGWSEs2csK7U6vfZ3BzUZW/0tPqcSpQqcNxMtY9TiUsNRj1uM6jX3byp7 AkEA6Ab+wvOTNRtES77OAYG9gHGZZ+iXjQJ/6Z7JehN4p41UbDIf9nNUOLUPL9z5V1uOYnl1CWoo Cw95cdhKXxEAqQJBAIU5Or6tp250ZdVslM27ewSyuY9UblfkIsk/EscFIdzbbDAqwkmsefW6yvTc mU3lgYCPYlKRG8c19tCuX1ENY5MCQAz37x9YW975Ai01ofAFn2DheJCNOINCI4IcROiU1AaRaKmP d6fftFJjFFE5iZovXNr2LOt0yn4rxD7vtuBvY9kCQGyty6YCB6qaD7qXPMhLrLbGajAIWd6ETgxv frK/BJu+buPfDky/g1FhI5R9iMtL1xH0JYLJlaVocU+xSeA9DkY= -----END RSA PRIVATE KEY-----";

编辑： 示例输出是：
