public byte[]
generateKey()

Overrides org.bouncycastle.crypto.generators.DESKeyGenerator.generateKey.

generate a secret key.

public void
init(KeyGenerationParameters
the parameters to be used for key generation
param)

Overrides org.bouncycastle.crypto.generators.DESKeyGenerator.init.

initialise the key generator - if strength is set to zero the key generated will be 192 bits in size, otherwise strength can be 128 or 192 (or 112 or 168 if you don't count parity bits), depending on whether you wish to do 2-key or 3-key triple DES.
