* Post-merge changes to SP 800-56A KDF (GH #1040)Jack Lloyd2017-05-063-77/+120
| | | | | | | Instead of using a template split the KDF into two different classes that both call a template utility function to actually run the KDF algo. Simplify the "empty salt" logic and avoid having to instantiate a hash object just to get the hash block size.

* Content:Tomasz Frydrych2017-04-031-1/+1
| | | | | | | | | * fixes for deprecated constructions in c++11 and later (explicit rule of 3/5 or implicit rule of 0 and other violations) * `default` specifier instead of `{}` in some places(probably all) * removal of unreachable code (for example `return` after `throw`) * removal of compilation unit only visible, but not used functions * fix for `throw()` specifier - used instead `BOTAN_NOEXCEPT` * removed not needed semicolons

* Add BOTAN_UNUSED in creator functionsJack Lloyd2017-01-271-0/+3
| | | | | | If all (say) stream ciphers are disabled, avoid unused arg warning. [ci skip]
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-1817-171/+171
| | | | | | Renames a couple of functions for somewhat better name consistency, eg make_u32bit becomes make_uint32. The old typedefs remain for now since probably lots of application code uses them.
* Fix missing include in kdf.cppJack Lloyd2016-11-291-0/+1

* Add a test for KDF::name()René Korthaus2016-11-151-1/+1
| | | | | | This required fixing some test vectors that previously omitted the MAC, defaulting to HMAC, that used the SHA-1 alias to SHA-160, and fixing X942_PRF::name().
* Add test vectors for HKDF-Expand and HKDF-ExtractRené Korthaus2016-11-151-2/+2
|
* Add full HKDF implementationRené Korthaus2016-11-123-8/+108
| | | | | | | | | | Adds the full HKDF as class HKDF, renames the existing HKDF, which only implemented the expansion step, to HKDF_Expand and adds the extraction step as HKDF_Extract. The latter two are usually only used seperately in protocols such as TLS. A normal user would go for the full HKDF.

* Remove ability to add OIDS at runtime. Remove global OID lock.Jack Lloyd2016-11-031-1/+0
| | | | | | | | | | | OID map is now generated from an input file on an as needed basis. Just uses a sequence of ifs - simple, fast, and small code size. Merges oid_lookup sub-module which was already required by asn1 anyway, so completely non-optional. Removes @neusdan's nice OID tests since without any runtime adds the tests are moot.

* Add final attribute to many classesJack Lloyd2016-01-105-6/+6
| | | | | | | In some cases this can offer better optimization, via devirtualization. And it lets the user know the class is not intended for derivation. Some discussion in GH #402
* Update and consolidate the test framework.Jack Lloyd2015-11-111-0/+1
| | | | | | | | | | | The tests previously had used 4 to 6 different schemes internally (the vec file reader framework, Catch, the old InSiTo Boost.Test tests, the PK/BigInt tests which escaped the rewrite in 1.11.7, plus a number of one-offs). Converge on a design that works everywhere, and update all the things. Fix also a few bugs found by the test changes: SHA-512-256 name incorrect, OpenSSL RC4 name incorrect, signature of FFI function botan_pubkey_destroy was wrong.

* Handle dependencies re static linking. GH #279Jack Lloyd2015-09-179-41/+41
| | | | | | | | | | | | | | Previously we were hanging on the type destructors to pull in the relevant objects. However that fails in many simple cases where the object is never deleted. For every type involved in the algo registry add static create and providers functions to access the algo registry. Modify lookup.h to be inline and call those functions, and move a few to sub-headers (eg, get_pbkdf going to pbkdf.h). So accessing the registry involves going through the same file that handles the initialization, so there is no way to end up with missing objs.
* Fix pbkdf, pk padding and ECDH registration for static linking.Jack Lloyd2015-09-112-1/+3
| | | | | | | | With this change the tests pass when linked against a static library built in the normal (non-amalgamation) fashion. Remove the restriction in configure.py, and have circleci build the clang static build as a non-amalg.
* Fix static lib registration for block, hash, mac, stream, kdfJack Lloyd2015-09-106-13/+49
| | | | | | | | | | | The support problems from having static libraries not work in the obvious way will be endless trouble. Instead have each set of registrations tag along in a source file for the basic type, at the cost of some extra ifdefs. On shared libs this is harmless - everything is going into the shared object anyway. With static libs, this means pulling in a single block cipher pulls in the text of all the them. But that's still strictly better than the amalgamation (which is really pulling in everything), and it works (unlike status quo).

| | | | | | | | | | | | ctypes Python wrapper that uses it. The API is intentionally designed to have a very simple ABI (extern "C", all structs are opaque, no memory ownership passing the FFI boundary, limited set of simple types as args) so the ctypes wrapper is quite simple. Currently ffi provides ciphers, hashes, MACs, RNGs, PBKDF, KDF, bcrypt, and most public key operations. Remove the old boost.python wrapper and all the build code for it.

* Remove algo factory, engines, global RNG, global state, etc.lloyd2015-02-043-6/+5
| | | | | | | | | | | | | | | Convert all uses of Algorithm_Factory and the engines to using Algo_Registry The shared pool of entropy sources remains but is moved to EntropySource. With that and few remaining initializations (default OIDs and aliases) moved elsewhere, the global state is empty and init and shutdown are no-ops. Remove almost all of the headers and code for handling the global state, except LibraryInitializer which remains as a compatability stub. Update seeding for blinding so only one hacky almost-global RNG instance needs to be setup instead of across all pubkey uses (it uses either the system RNG or an AutoSeeded_RNG if the system RNG is not available).
