If an application doesn't specify a random seed using kseed, the same
random seed is used for every invocation of DSA.

Subject: Signatures and Ciphers that need random values

   When computing a DSA signature, I need to generate a random value
(generally called k). If I'm signing using PSS (Probabilistic Signature
Scheme, similar to OAEP enveloping), I need to generate random values.
And speaking of OAEP, I will need to generate random values when
encrypting.

   It seems to me it would be a good idea to allow callers to pass in a
SecureRandom object at some point in the Signature and Cipher classes
(possibly init).

   Incidentally, in the SUN implementation of DSA that I got when I
downloaded JDK 1.1 (and 1.1.1), how do you generate the random k? It
appeared to be the same k every single time.
