* Add test vectors for block cipher padding modesRené Korthaus2016-07-112-2/+5
| | | | | | | | | | | Exports get_bc_pad() to be used from tests. Adds separate handcrafted tests for block cipher padding modes. They were previously only tested implicitly during the block cipher modes of operation tests, though not all padding modes were covered. And in case a mode of operation is not part of the enabled modules, the previously tested padding modes are not covered at all. Fixes an off-by-one bug in the previously untested ANSI X9.23 padding mode, where the number of zero bytes in the pad was one more than allowed by the standard.

* Add final attribute to many classesJack Lloyd2016-01-101-4/+4
| | | | | | | In some cases this can offer better optimization, via devirtualization. And it lets the user know the class is not intended for derivation. Some discussion in GH #402

| | | | | | | | | | | | | | | | | Transforms and BlockCiphers. Registration for all types is done at startup but is very cheap as just a std::function and a std::map entry are created, no actual objects are created until needed. This is a huge improvement over Algorithm_Factory which used T::clone() as the function and thus kept a prototype object of each type in memory. Replace existing lookup mechanisms for ciphers, AEADs, and compression to use the transform lookup. The existing Engine framework remains in place for BlockCipher, but the engines now just call to the registry instead of having hardcoded lookups. s/Transformation/Transform/ with typedefs for compatability. Remove lib/selftest code (for runtime selftesting): not the right approach.
