==== Noncompliant code example

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

fun main(args: Array<String>) {
    try {
        val des = Cipher.getInstance("DES") // Noncompliant
    } catch (e: NoSuchAlgorithmException) {
        // ...
    } catch (e: NoSuchPaddingException) {
        // ...
    }
}

==== Compliant solution

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

fun main(args: Array<String>) {
    try {
        val aes = Cipher.getInstance("AES/GCM/NoPadding")
    } catch (e: NoSuchAlgorithmException) {
        // ...
    } catch (e: NoSuchPaddingException) {
        // ...
    }
}
