* Helpful commentJack Lloyd2017-10-111-1/+2

* Make poly_dbl.h a submodule of utilsJack Lloyd2017-09-271-0/+1
| | | | | Only required by a few modules and if none of them are in use then the whole thing can just be skipped from the build.
* Avoid debug iterator errorJack Lloyd2017-09-241-6/+12
|
* Test SIV multi-AD functionJack Lloyd2017-09-241-2/+2
|
* Better tests for SIVJack Lloyd2017-09-242-22/+33
| | | | | | | | | | | | Correct errors in the AEAD tests that assumed process/update always return something - that isn't true for SIV Minor optimizations in CMAC and CTR to cache the block size instead of making a zillion virtual calls for it. Generalize SIV slightly to where it could support a non-128 bit cipher, but don't pull the trigger on it since I can't find any implementations to crosscheck with.
* Further build/test fixes for restricted configurationsJack Lloyd2017-09-242-1/+8

* More include header cleanupsJack Lloyd2017-09-212-3/+5
|
* Header file cleanupsJack Lloyd2017-09-211-1/+0
| | | | Some help from include-what-you-use
* Change header guard format to BOTAN_FOO_H_Jack Lloyd2017-09-201-2/+2
| | | | | | ISO C++ reserves names with double underscores in them Closes #512
* Add API stability annotations.Jack Lloyd2017-09-191-3/+3
| | | | | Defined in build.h, all equal to BOTAN_DLL so ties into existing system for exporting symbols.
* Improve polynomial doubling code, move to utilJack Lloyd2017-08-151-3/+4
| | | | | | | | | Now does 64-bits at a time instead of 8 bits, and avoids conditional timing channel on the XOR carry. Confirmed that at least GCC 7 and Clang 4 on x86-64 compile the functions without conditional jumps. Also removes CMAC as a dependency of OCB, which only needed it in order to call CMAC::poly_double
* Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-021-1/+3

* Convert to using standard uintN_t integer typesJack Lloyd2016-12-182-24/+24
| | | | | | 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.
* Correct output_length bug in SIV and ChaCha20Poly1305 alsoJack Lloyd2016-11-261-1/+1
|
* Cipher_Mode and AEAD_Mode improvementsDaniel Neus2016-11-082-1/+11
| | | | | | | | | | | | See PR #552 - Add Cipher_Mode::reset() which resets just the message specific state and allows encrypting again under the existing key - In Cipher_Mode::clear() (at some planes) use cipher->clear() instead of resetting the pointer which would make the cipher object unusable - EAX_Decryption::output_length() bugfix?! Now its possible to decrypt an empty ciphertext (just a tag) - Bugfix for GCM_Decryption::finish() - set tag length in GCM_Mode::name() - Cipher_Mode tests: add tests for reset()and process() - AEAD_Mode tests: add tests for reset(), clear(), update() and process()
* Remove Algo_RegistryJack Lloyd2016-10-211-1/+0
| | | | | | | I repent my use of global constructors. I repent my use of global locks. Hopefully I will never touch this code again. :)

* SIV is restricted to 128 bit ciphersJack Lloyd2016-10-021-0/+2
|
* Cipher_Mode API improvementsJack Lloyd2016-09-012-11/+6
| | | | | | | | | | | | | | | | | | | | The Cipher_Mode::update API is more general than needed to just support ciphers (this is due to it previously being an API of Transform which before 8b85b780515 was Cipher_Mode's base class) Define a less general interface `process` which either processes the blocks in-place, producing exactly as much output as there was input, or (SIV/CCM case) saves the entire message for processing in `finish`. These two uses cover all current or anticipated cipher modes. Leaves `update` for compatability with existing callers; all that is needed is an inline function forwarding to `process`. Removes the return type from `start` - in all cipher implementations, this always returned an empty vector. Adds BOTAN_ARG_CHECK macro; right now BOTAN_ASSERT is being used for argument checking in some places, which is not right at all.
* cppcheck fixes: Class 'X' has a constructor with 1 argument that is not ↵Daniel Neus2016-03-051-3/+3

* Add final attribute to many classesJack Lloyd2016-01-101-2/+2
| | | | | | | 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
* Same treatment for cipher modesJack Lloyd2015-09-101-2/+0

* Fix module combi: adler32,sivSimon Warta2015-07-081-0/+5

* Add a runtime map of string->func() which when called returnlloyd2015-01-281-3/+4
| | | | | | | | | | | | | | | | | Transforms and BlockCiphers. Registration for all types is done at startup but is very cheap as just a std::function and a std::map entry are created, no actual objects are created until needed. This is a huge improvement over Algorithm_Factory which used T::clone() as the function and thus kept a prototype object of each type in memory. Replace existing lookup mechanisms for ciphers, AEADs, and compression to use the transform lookup. The existing Engine framework remains in place for BlockCipher, but the engines now just call to the registry instead of having hardcoded lookups. s/Transformation/Transform/ with typedefs for compatability. Remove lib/selftest code (for runtime selftesting): not the right approach.
* Ensure all files have copyright and license info.lloyd2015-01-102-2/+2
| | | | | Update license header line to specify the terms and refer to the file, neither of which it included before.
* Replace Transformatio::nstart with start_raw so we can do a full setlloyd2014-11-052-10/+7
| | | | of overloads in the base class with the same name.
* Guess I won't be needing theselloyd2014-01-181-1/+0
|
* Use unique_ptr instead of bare pointers and explicit delete in block, mac, hash.lloyd2014-01-181-3/+3
| | | | m_ namespaced everything while I'm in there. Changed CMAC poly_double signature.
* Split off the keyed interfaces of transform to Keyed_Transformlloyd2014-01-181-3/+3
| | | | | Remove the unhelpful 'Algorithm' base class which had previously acted more or less as a global base.
* Move lib into srclloyd2014-01-103-0/+297
