+# Sun provider DRBG configuration and default instantiation request.
+#
+# NIST SP 800-90Ar1 lists several DRBG mechanisms. Each can be configured
+# with a DRBG algorithm name, and can be instantiated with a security strength,
+# prediction resistance support, etc. This property defines the configuration
+# and the default instantiation request of "DRBG" SecureRandom implementations
+# in the SUN provider. (Other DRBG implementations can also use this property.)
+# Applications can request different instantiation parameters like security
+# strength, capability, personalization string using one of the
+# getInstance(...,SecureRandomParameters,...) methods with a
+# DrbgParameters.Instantiation argument, but other settings such as the
+# mechanism and DRBG algorithm names are not currently configurable by any API.
+#
+# Please note that the SUN implementation of DRBG always supports reseeding.
+#
+# The value of this property is a comma-separated list of all configurable
+# aspects. The aspects can appear in any order but the same aspect can only
+# appear at most once. Its BNF-style definition is:
