+# TLS key limits on symmetric cryptographic algorithms
+#
+# This security property sets limits on algorithms key usage in TLS 1.3.
+# When the amount of data encrypted exceeds the algorithm value listed below,
+# a KeyUpdate message will trigger a key change.  This is for symmetric ciphers
+# with TLS 1.3 only.
+#
+# The syntax for the property is described below:
+#   KeyLimits:
+#       " KeyLimit { , KeyLimit } "
+#
+#   WeakKeyLimit:
+#       AlgorithmName Action Length
+#
+#   AlgorithmName:
+#       A full algorithm transformation.
+#
+#   Action:
+#       KeyUpdate
+#
+#   Length:
+#       The amount of encrypted data in a session before the Action occurs
+#       This value may be an integer value in bytes, or as a power of two, 2^29.
+#
+#   KeyUpdate:
+#       The TLS 1.3 KeyUpdate handshake process begins when the Length amount
+#       is fulfilled.
+#
+# Note: This property is currently used by OpenJDK's JSSE implementation. It
+# is not guaranteed to be examined and used by other implementations.
