| | | | | | | | | | | | | | | | | | | | was not the right size for a signature (following DSA). This would silently convert to an empty vector which we would treat as a valid message on the return. However the EMSA checks will always fail so not a huge problem. While checking this out I noticed that an empty value for EMSA4 would result in us reading memory we didn't own.

| | | | | | | conditionals to help avoid timing anylsis. Unfortunately GCC is too smart for us and compiles it to jumps anyway; probably would need to put the delim search into its own function and pass variables by volatile pointers to force the compiler to do what we want.

* More vector->pointer conversion removals.lloyd2010-09-132-3/+2
| | | | | | | | | | | Add RandomNumberGenerator::random_vec, which takes an length n and returns a new SecureVector with randomized contents of that size. This nicely covers most of the cases where randomize was being called on a vector, and is a little cleaner in the code as well, instead of vec.resize(length); rng.randomize(&vec[0], vec.size()); we just write vec = rng.random_vec(length);
* Anywhere where we use MemoryRegion::begin to get access to the raw pointerlloyd2010-09-131-2/+2

* Rename MemoryRegion::destroy to MemoryRegion::clear to match STLlloyd2010-09-081-3/+3
|
* Big, invasive but mostly automated change, with a further attempt atlloyd2010-09-072-4/+2
| | | | | | | | | | | | | | harmonising MemoryRegion with std::vector: The MemoryRegion::clear() function would zeroise the buffer, but keep the memory allocated and the size unchanged. This is very different from STL's clear(), which is basically the equivalent to what is called destroy() in MemoryRegion. So to be able to replace MemoryRegion with a std::vector, we have to rename destroy() to clear() and we have to expose the current functionality of clear() in some other way, since vector doesn't support this operation. Do so by adding a global function named zeroise() which takes a MemoryRegion which is zeroed. Remove clear() to ensure all callers are updated.

* 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.

* 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.

* Remove the 'realname' attribute on all modules and cc/cpu/os info files.lloyd2009-10-2910-20/+0

* Remove all exception specifications. The way these are designed in C++ islloyd2009-10-2211-13/+13

* 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).

* 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.
