*	Remove the now no-op classes PK_Encrypting_Key,	lloyd	2010-03-08	1	-4/+4
\| \| \| \| \|	PK_Decrypting_Key, PK_Signing_Key, PK_Verifying_with_MR_Key, and PK_Verifying_wo_MR_Key.
*	Add ops for ElGamal encryption and decryption.	lloyd	2010-03-05	1	-0/+13
\| \| \| \| \|	Note: blinding is not currently being used for RSA, RW, DH or ElGamal, which used to have them. This should be added back before release.
*	Constify sign and verify ops	lloyd	2010-03-05	1	-6/+16
\|
*	Rename PK_Ops::Signature_Operation to PK_Ops::Signature	lloyd	2010-03-05	1	-4/+4
\| \| \| \|	Rename PK_Ops::KA_Operation to PK_Ops::Key_Agreement
*	Add verification ops for all signature key types	lloyd	2010-03-05	1	-6/+37
\|
*	Remove the sign() operation from the public key objects, totally replaced	lloyd	2010-03-05	1	-0/+25
\| \| \| \| \| \|	by using the ops. Add real ECDSA test vectors (two found in ANSI X9.62)
*	Add signature generation operation classes. Remove sign() from	lloyd	2010-03-05	1	-0/+35
\| \| \| \| \| \|	PK_Signing_Key, though for the moment the class remains because there are a few pieces of code that use it to detect if signatures are supported, or for passing to functions in look_pk
*	This checkin represents a pretty major change in how PK operations are	lloyd	2010-03-04	1	-0/+38
	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.
