org.spongycastle.jcajce.provider.symmetric.DES.KeyGenerator

Enclosing class:

DES

public static class DES.KeyGenerator
extends BaseKeyGenerator

DES - the default for this is to generate a key in a-b-a format that's 24 bytes long but has 16 bytes of key material (the first 8 bytes is repeated as the last 8 bytes). If you give it a size, you'll get just what you asked for.
