* Partially protect OAEP decoding against a timing attack. Possibilitylloyd2010-05-121-12/+28
| | | | | | | | of this pointed out by Falko Strenzke. The timing differences between different error conditions could lead to attacks even with the same error message. Instead use a (mostly) straightline implementation. However scanning for the delim byte is still timing/input dependenant, so this is not a 100% fix.
* Fix EMSA_Raw in the case where the original input had leading 0 bytes.lloyd2010-04-211-1/+19

* Clean up exceptions. Remove some unused ones like Config_Error. Makelloyd2010-01-051-1/+1
| | | | | | | Invalid_Argument just a typedef for std::invalid_argument. Make Botan::Exception a typedef for std::runtime_error. Make Memory_Exhaustion a public exception, and use it in other places where memory allocations can fail.
* Make many more headers internal-only.lloyd2009-12-161-1/+1
| | | | | | | | | | | | | Fixes for the amalgamation generator for internal headers. Remove BOTAN_DLL exporting macros from all internal-only headers; the classes/functions there don't need to be exported, and avoiding the PIC/GOT indirection can be a big win. Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc For GCC, use -fvisibility=hidden and set BOTAN_DLL to the visibility __attribute__ to export those classes/functions.
* Full working amalgamation build, plus internal-only headers concept.lloyd2009-12-1610-67/+0

* Remove the 'realname' attribute on all modules and cc/cpu/os info files.lloyd2009-10-2910-20/+0
| | | | | Pretty much useless and unused, except for listing the module names in build.h and the short versions totally suffice for that.
* Remove all exception specifications. The way these are designed in C++ islloyd2009-10-2211-13/+13
| | | | | | just too fragile and not that useful. Something like Java's checked exceptions might be nice, but simply killing the process entirely if an unexpected exception is thrown is not exactly useful for something trying to be robust.

* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-3021-198/+240
| | | | | | | | | | | | | | | 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).

| | | | | | | add a digest identifier. This was a feature requested on the mailing list. Apparently this scheme is called CKM_RSA_PKCS in PKCS #11, and is supported by a number of libraries, including QCA.

* Rickard Bondesson reported on the mailing list that he had noticedlloyd2008-11-281-11/+13
| | | | | | | | | | | | | | a discrepency between OpenSSL and Botan when generating SHA-512/EMSA3 signatures. In fact it turns out that the EMSA3 identifier for SHA-512 contained a typo and was incorrect. Unfortunately this means that SHA-512/EMSA3 signatures generated by Botan up until now will not be accepted by other implementations, and the signatures by other implementations would not be accepted by Botan. Currently I am not making any provision for backwards compatability with the old incorrect hash identifier, since I am assuming/guessing that SHA-512/EMSA3 is not a very common combination.

* Split base.h into block_cipher.h and stream_cipher.hlloyd2008-11-081-1/+1
| | | | | | It turned out many files were including base.h merely to get other includes (like types.h, secmem.h, and exceptn.h). Those have been changed to directly include the files containing the declarations that code needs.
