* This checkin represents a pretty major change in how PK operations arelloyd2010-03-0421-282/+221
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Quite the hack, here.lloyd2010-03-043-1/+11
| | | | | | | | | | | | | | | | | GOST 34.10 public keys use a funky encoding. There is no standard for PKCS #8 format private keys, so the obvious choice is to act exactly the same as ECDSA/ECDH (following the rule of thumb that if you're going to make up a random non-standard thing, at least try to copy something that's standard for something else). However the public key encoding uses a weird scheme for encoding the OID in the algorithm identifier, which we don't want to use for the PKCS #8 encoding. Add a new function to Private_Key, pkcs8_algorithm_identifier, which by default just calls algorithm_identifier(). However GOST_3410_PrivateKey overrides it, and calls EC_PublicKey::algorithm_identifier(), basically skipping over the virtual function hierarchy, so it doesn't pick up the funky format from the public key's version of algorithm_identifier().
