Non-Compliant Code Examples
class MyClass {
public void test1() {
Cipher c = Cipher.getInstance("RSA/NONE/NoPadding");
c.init(Cipher.ENCRYPT_MODE, k, iv);
byte[] cipherText = c.doFinal(plainText);
}
public void test2() {
Cipher c = javax.crypto.Cipher.getInstance("RSA/NONE/NoPadding");
c.init(Cipher.ENCRYPT_MODE, k, iv);
byte[] cipherText = c.doFinal(plainText);
}
}
Compliant Code Examples
class MyClass {
public void test() {
Cipher c = Cipher.getInstance("RSA/ECB/OAEPWithMD5AndMGF1Padding");
c.init(Cipher.ENCRYPT_MODE, k, iv);
byte[] cipherText = c.doFinal(plainText);
}
}
