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);     } }
