* This checkin represents a pretty major change in how PK operations arelloyd2010-03-041-9/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-301-10/+12
| | | | | | | | | | | | | | | up during the Fedora submission review, that each source file include some text about the license. One handy Perl script later and each file now has the line Distributed under the terms of the Botan license after the copyright notices. While I was in there modifying every file anyway, I also stripped out the remainder of the block comments (lots of astericks before and after the text); this is stylistic thing I picked up when I was first learning C++ but in retrospect it is not a good style as the structure makes it harder to modify comments (with the result that comments become fewer, shorter and are less likely to be updated, which are not good things).
