Non-Compliant Code Examples

class MyClass {

    public void test1() {
        Cipher c = Cipher.getInstance("AES/ECB/NoPadding");
        c.init(Cipher.ENCRYPT_MODE, k, iv);
        byte[] cipherText = c.doFinal(plainText);
    }
    public void test2() {
        Cipher c = javax.crypto.Cipher.getInstance("AES/ECB/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("AES/GCM/NoPadding");
        c.init(Cipher.ENCRYPT_MODE, k, iv);
        byte[] cipherText = c.doFinal(plainText);
    }
