==== Noncompliant code example

[source,java,diff-id=1,diff-type=noncompliant]
----
import javax.crypto.Cipher;
import java.security.NoSuchAlgorithmException;
import javax.crypto.NoSuchPaddingException;

public static void main(String[] args) {
    try {
        Cipher des = Cipher.getInstance("DES"); // Noncompliant
    } catch(NoSuchAlgorithmException|NoSuchPaddingException e) {
        // ...
    }
}
----

==== Compliant solution

[source,java,diff-id=1,diff-type=compliant]
----
import javax.crypto.Cipher;
import java.security.NoSuchAlgorithmException;
import javax.crypto.NoSuchPaddingException;

public static void main(String[] args) {
    try {
        Cipher aes = Cipher.getInstance("AES/GCM/NoPadding");
    } catch(NoSuchAlgorithmException|NoSuchPaddingException e) {
        // ...
    }
}
