如何使用公钥加密字符串以在php中生成静态字符串而不是动态字符串？

Question

I am trying to encrypt a string using a public key but each time I get a new string. Any workarounds to getting a static string?

Here is my code

$publicKey = openssl_pkey_get_public(file_get_contents("file://C:/Users/nick/Dropbox/wamp/www/samples/mycert.cer"));
$plaintext = "Matr!x12";
openssl_public_encrypt($plaintext, $encrypted, $publicKey, OPENSSL_PKCS1_PADDING);
echo base64_encode($encrypted);

Well, obviously SSL encryption generates different results each time it's involved for security reasons. If you for whatever reason you need to have identical results multiple times you cannot use "real encryption". Maybe just use MD5 or some other hash function but be aware that you cannot get secrets that cannot be decrypted (with enough effort).
