Hi All Webrev updated again at
http://cr.openjdk.java.net/~weijun/8051408/webrev.10/ http://cr.openjdk.java.net/~weijun/8051408/webrev.10/spec http://cr.openjdk.java.net/~weijun/8051408/webrev.10/specdiff Changes since webrev.09: 1. The first line in DrbgParameters: - * This class specifies the parameters used by a DRBG. + * This class specifies the parameters used by a DRBG (Deterministic + * Random Bit Generator). 2. Two new methods for DrbgParameters$Capability: public boolean supportsReseeding(); public boolean supportsPredictionResistance(); So you will be able to write drbg = SecureRandom.getInstance("DRBG"); SecureRandomParameters params = drbg.getParameters(); if (params instanceof DrbgParameters.Instantiate) { DrbgParameters.Instantiate ins = (DrbgParameters.Instantiate) params; if (ins.getCapability().supportsReseeding()) { drbg.reseed(); } } 3. More descriptive text in exception thrown.
