| | | | | | 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 arelloyd2010-03-042-16/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 camelloyd2009-03-308-74/+90
| | | | | | | | | | | | | | | 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).
* GOST was using a completely non-standard set of sboxes. Change it to uselloyd2009-03-271-5/+5
| | | | | | | | | | | | | | | GostR3411_94_TestParamSet, this is compatible with the implementations in Crypto++ and OpenSSL. This is not backwards compatible, though once the implementation supports multiple param sets (which is required, unfortunately, for compatability with various standards by CryptoCom, who have defined not one but at least 4 (!!!) different sboxes to use with GOST), I may offer Botan's previous sbox set as an option. Since adding the GOST hash function (34.11) and signing algorithm (34.10) are on the long term agenda (request by Rickard Bondesson, as the Russian authorities want to use their local standards for their DNSSEC use), I renamed the block cipher class (which had been just 'GOST') to GOST_28147_89 to minimize future name clashes.
* Add an Algorithm_Factory& argument to Engine::get_cipher to avoid alloyd2008-11-232-5/+6
| | | | dependency on libstate.h
* Library_State had two functions that did the same thing,lloyd2008-11-121-1/+1
| | | | | | | | | | | | | | | algo_factory and algorithm_factory. This is confusing so for consistency/simplicity, remove algo_factory, making algorithm_factory the function to call. In 1.7.14, several functions in lookup.h, including retrieve_block_cipher, retrieve_hash, etc were changed to accept a Library_State& reference. However it turns out with the modified design I've settled upon for 1.8 that it is not necessary to change those interfaces; instead they always refer to the global_state algorithm factory which is exactly the semantics one would expect/desire 99% of the time (and is source compatible with code written for 1.6, also a plus)
* Remove support for provider identifiers from SCAN_Name - it turns out thislloyd2008-11-121-1/+1
| | | | | | | | | | | | was not the right place to keep track of this information. Also modify all Algorithm_Factory constructor functions to take instead of a SCAN_Name a pair of std::strings - the SCAN name and an optional provider name. If a provider is specified, either that provider will be used or the request will fail. Otherwise, the library will attempt best effort, based on user-set algorithm implementation settings (combine with benchmark.h for choosing the fastest implementation at runtime) or if not set, a static ordering (preset in static_provider_weight in prov_weight.cpp, though it would be nice to make this easier to toggle).
