| | | | | | | | | | | | | destructor function which would delete the engine; this was to handle the case that the heaps were not shared between the application and the library. However in this case we have bigger problems, because we want to be able to pass std::strings into the engine, and additionally be able to return objects from the library which are later deleted by the algorithm factory. So without a major restructuring we can't support this style of operation anyway; the DLL and application must share the same heap. This can be done on Windows using the /MD linking scheme for both the library and the DLL. The library already uses this model by default on Windows.

| | | | | | | | | | | | | | | constant time and on a Nehalem is significantly faster than the table based version. This implementation technique was invented by Mike Hamburg and described in a paper in CHES 2009 "Accelerating AES with Vector Permute Instructions". This code is basically a translation of his public domain x86-64 assembly code into intrinsics. Todo: Adding support for AES-192 and AES-256; this just requires implementing the key schedules. Currently only tested on an i7 with GCC (32 and 64 bit code); testing/optimization on 32-bit processors with SSSE3 like the Atom, and with Visual C++ and other compilers, are also todos.

It will almost certainly work on BSDs and Solaris as well, though, and should be easy to extend to support Win32-style dynamic loading. Also add a new engine, Dynamically_Loaded_Engine, which loads up a new Engine object from a shared library/DLL.

Use the operations public op to hide the secret, for instance the seed for a DH blinding variable is 2^x mod p. Make use of being able to mutate internal structures in the RW signer, since that does have access to a PRNG, so use it to initialize the blinder on first call to sign().

* This checkin represents a pretty major change in how PK operations arelloyd2010-03-044-25/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | performed. Up until now, each key object (eg DSA_PublicKey or ECDH_PrivateKey) had two jobs: contain the key material, and know how to perform any operations on that key. However because of a desire to support alternative implementations (GNU MP, hardware, whatever), there was a notion of operations, with the key objects containing an op that they got via engine rather than actually implementing the underlying algorithms directly. Now, represent the operation as an abstract interface (typically mapping a byte string to a byte string), and pass a plain Public_Key& or Private_Key& to the engine. The engine does any checks it wants (eg based on name, typeid, key sizes, etc), and either returns nothing (I'll pass) or a pointer to a new operation that represents signatures or encryption or what-have-you using that key. This means that plain key objects no longer contain operations. This is a major break with the traditional interface. On the other hand, using these 'bare' operations without padding, KDFs, etc is 99% of the time a bad idea anyway (and if you really need them, there are options so you get the bare op but via the pubkey.h interfaces). Currently this change is only implemented for DH and ECDH (ie, key agreement algorithms). Additionally the optional engines (gnump and openssl) have not been updated. I'll probably wait to touch those until after I can change them all in one go for all algos.
