Without OAEP in RSA encryption, it takes less work for an attacker to decrypt the data or infer patterns from the ciphertext. This rule logs an issue when ``openssl_public_encrypt`` is used with one the following padding constants: ``OPENSSL_NO_PADDING`` or ``OPENSSL_PKCS1_PADDING`` or ``OPENSSL_SSLV23_PADDING``.

function encrypt($data, $key) {

|
$crypted='';
|
|
openssl_public_encrypt($data, $crypted, $key, OPENSSL_NO_PADDING); // Noncompliant
|
|
return $crypted;

}
