* Rename Integrity_Failure to Invalid_Authentication_TagJack Lloyd2019-01-181-1/+1
| | | | | | | | | This makes the meaning and usage more clear. Add a specific error type so invalid tags can be distinguished without having to catch that specific type. See also #1813
* Fix some warnings from PVS-StudioJack Lloyd2019-01-171-0/+1
| | | | No real bugs, but pointed out some odd constructs and duplicated logic
* Make exceptions easier to translate to error codesJack Lloyd2018-11-231-2/+2
| | | | | | | | | | | Avoid throwing base Botan::Exception type, as it is difficult to determine what the error is in that case. Add Exception::error_code and Exception::error_type which allows (for error code) more information about the error and (for error type) allows knowing the error type without requiring a sequence of catches. See GH #1742
* Add RAII versions of get_cipher_mode and get_aeadJack Lloyd2018-04-071-6/+2
| | | | See also #1526
* Another missing includeJack Lloyd2017-09-211-0/+1
| | | | For whatever reason only seen on the Kullo OS X build
* More include header cleanupsJack Lloyd2017-09-212-1/+2
|
* 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 Lloyd2017-09-191-2/+2
| | | | | Defined in build.h, all equal to BOTAN_DLL so ties into existing system for exporting symbols.
* Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-021-1/+3
|
* Convert to using standard uintN_t integer typesJack Lloyd2016-12-182-19/+19
| | | | | | 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.
* Remove Algo_Registry usage from public key code.Jack Lloyd2016-10-071-2/+3
| | | | | | | | Instead the key types exposes operations like `create_encryption_op` which will return the relevant operation if the algorithm supports it. Changes pubkey.h interface, now RNG is passed at init time. Blinder previous created its own RNG, now it takes it from app.
* Add KDF1 as explicit dependency in MCEIESJack Lloyd2016-02-151-0/+1
| | | | | | | | | | Previously MCEIES used KEM with a raw SHA-512 hash. When the KDF oriented KEM interface was added in 72f0f0ad2a it switched to using KDF1(SHA-512) since for a 64-byte output and no salt, the output matches the original hash. This avoids breaking the format. Prevents runtime failures when MCEIES is enabled in the build but KDF1 is not. GH #369
* V816 It is more efficient to catch exception by reference rather than by ↵Daniel Neus2016-02-081-1/+1
| | | | value. asn1_time.cpp 159
* Add generalized KEM interfaceJack Lloyd2015-12-261-7/+6
| | | | | | Convert McEliece KEM to use it Add RSA-KEM
* Reroot the exception hierarchy into a toplevel Exception classJack Lloyd2015-12-111-4/+4
| | | | | | | | As the alternatives are unfortunate for applications trying to catch all library errors, and it seems deriving from std::runtime_error causes problems with MSVC DLLs (GH #340) Effectively reverts 2837e915d82e43
* Update and consolidate the test framework.Jack Lloyd2015-11-111-0/+4
| | | | | | | | | | | 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.
* McEliece cleanupsJack Lloyd2015-09-292-18/+19
| | | | | | | | | | | | | | | | | | | | Remove and consolidate various headers Reduce memory usage of GF2m_Field by sharing the log and exponent tables across all instances of a particular word size. Remove McEliece_Public_Operation and McEliece_Private_Operation which were difficult to use safely. Instead only the KEM operations are exposed. Add McEliece_PublicKey::random_plaintext_element Add command line `mce` tool and some McEliece documentation Convert the speed program to check McEliece keys of the suggested size Add McEliece KATs for both key generation and KEM Fix HMAC_DRBG constructor which derefed a pointer before its time
* Fix module combi: adler32,mceSimon Warta2015-07-082-4/+9

* More changes for use with debug STLSimon Warta2015-06-301-3/+3

* lib/pubkey: Convert &vec[0] to vec.data()Simon Warta2015-06-231-4/+4

* 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.
* Add MCEIES, an integrated encryption system using McEliece and AES-256/OCBlloyd2015-01-083-0/+154
