Please take a review at http://cr.openjdk.java.net/~weijun/8156213/webrev.00/
In its initial changeset, The SUN implementation of DRBG supports all algorithms described in NIST SP 800-90Ar1. However, one algorithm is already considered weak today (3KeyTDEA) and another is likely to be consider weak quite soon (SHA-1). We should stop supporting them right from the beginning. It's a relief to say default strength is 128 for all mech/alg combinations. There is no interoperability or compatibility problem for SecureRandom. Thanks Max
