This means, for instance, + that the SSSE3 and AES-NI implementations of AES are always included + in x86 builds, relying on runtime cpuid checking to prevent their + use on CPUs that do not support those operations. + +* Adds a new interface for benchmarking, :cpp:func:`time_algorithm_ops`, + which returns a map of operations to operations per second. For + instance now both encrypt and decrypt speed of a block cipher can be + checked, as well as the key schedule of all keyed algorithms. It + additionally supports AEAD modes. + +* A new TLS policy :cpp:class:`NSA_Suite_B_128` is available, which + will negotiate only the 128-bit security NSA Suite B. See + :rfc:`6460` for more information about Suite B. |
