DES.KeyGenerator (Bouncy Castle Library 1.54 API Specification)
Date: 2015-12-29

org.bouncycastle.jcajce.provider.symmetric

## Class DES.KeyGenerator

- java.lang.Object
- - javax.crypto.KeyGeneratorSpi
  - - org.bouncycastle.jcajce.provider.symmetric.util.BaseKeyGenerator
    - - org.bouncycastle.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.
