* Modify the S2K interface. Instead of being stateful in terms of the saltlloyd2010-02-0111-136/+48
| | | | | | | | | | | and iteration count, force it to be passed to each call to derive_key. So remove current_salt, set_iterations, new_random_salt, and change_salt functions from S2K interface. Update examples and test application to match. While I was in there, change the passhash example to use 64 bit salts and 128 bit PBKDF2 outputs.

* Fix several buffering problems in the XTS implementation that wouldlloyd2010-01-251-9/+31
| | | | | | | | | | | | | cause bad results if the input was not an even multiple of the block size. No released version was broken because the changes which caused the problem were related to using Buffered_Filter, which was introduced after 1.9.3 was released. Add more XTS test vectors using AES, Serpent, and Twofish. The AES tests come from Brian Gladman's XTS implementation. The Serpent and Twofish tests were generated by botan.

* Prevent a crash in GMP_Engine if the library is shutdown and thenlloyd2010-01-222-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | reinitialized. It would cache an Allocator pointer on first use, and then never zero it, so after the reinit the pointer would be going to a now deallocated Allocator object. Encountered in the SoftHSM test suite, reported by Ondrej Sury. Use a simple reference counting scheme to zero the pointer, and reset the GNU MP memory functions. This also fixes a quite obscure and never reported bug, that if the GMP engine was used, and if the library was deinitialized but then the program tried to use GNU MP, the allocator functions would crash. Now after deinit the allocator funcs revert to the defaults. The reference count is not updated atomically so this is not thread safe, but seems a non-issue; the only time this could happen (especially now that the GMP engine header is internal-only) is if multiple threads were attempting to initialize / shutdown the library at once - which won't work anyway for a variety of reasons, including contention on the (unlocked) global_lib_state pointer. If at some point thread safety is useful here, the refcnt can be locked by a mutex, or kept in an atomic<unsigned int>.
