Hi Damjan, All, That seems to have fixed the crashes on Windows...

The Visual Studio 2008 compiler doesn't have the ::std::vector::data() method (even though it should, itwas part of the C++98/03 standard), I had to use &vector[0] instead. Also that ancient OpenSSL version we use internally, 1.0.x, uses EVP_MD_CTX_create()/destroy() instead of EVP_MD_CTX_new()/free(). Finallysome template function was unhappy about parameter type ambiguity (eventhough superior compilers like Clang are perfectly happy), and I had to add casts.

Also a number of other fixes and improvements: - Sorted main/oox/source/token/tokens.txt so it's in alphabeticalorder(wrong order might have broken certain tokens?). - Refactored how OOXML encryption is generally handled. It's nowinitsown file. - Added logging to the FilterDetect class. It logs to theoffice-widedefault logger.- Added a flush() method to the BinaryXOutputStream class.- Changed FilterDetect to use XMultiComponentFactory and XComponentContext instead of the deprecated XMultiServiceFactory. - Error handling was generally improved. - Exception safety and some memory safety (::std::vector insteadofnew[])in all the new code. Memory leaks should not be possible.Much of the code involved in the decryption was ported from the excellentApache POI project, so it's been credited in our NOTICE file.Patch by: me ---snip--- It took much longer than I expected:The MS-OFFCRYPTO specification was unclear, and plain wrong in someparts,eg. "SHA-1" in the spec but "SHA1" in actual OOXML documents; I've madeourcode support both. The "Standard" encryption from MS Office 2007 that we already supportedwasitself a mess, and much work was needed to refactor and clean up thatcodebefore the "Agile" encryption could also be added.Then XML parsing had to be added, since Agile encryption specifiessettingsin XML instead of binary like Standard encryption did. XML handling in OpenOffice is pretty outdated, with no support for namespaces, but atleastthe newer "FastParser" does support namespaces and is in fact very fastbecause it converts strings to unique integers, and packs namespacesintobit fields, for faster comparisons. I ended up updating the main/ooxFastParser to support the new Agile encryption namespaces and elements. MS-OFFCRYPTO also only describes encryption, not decryption, and sincewecan only read OOXML, only decryption matters. Apache POI code was tremendously helpful in figuring out the decryption process. Most of the decryption code I added was just ported directlyfromtheirs, and thus I've added Apache POI to our NOTICE file (please checkthat I've done it correctly). Also several bugs were figured out bysimultaneously stepping through our code in gdb and their code inNetBeans,and comparing respective values. A big thank you to the Apache POIdevelopers, whose OOXML support is still better than ours in many ways!I used OpenSSL for all the message digest and encryption stuff, bothbecause our MD5 and SHA1 algorithms are broken (bug 127661), andbecauseAgile encryption requires many digests and ciphers that OpenSSLsupportsbut we don't. Anyway, it works now. All encrypted OOXML files should work, eg. text documents, spreadsheets, presentations, etc. Other issues I am aware of: - We only support password encrypted documents. Certificate encrypted documents: not yet. ODF 1.3 also added certificate encryption, so maybe that's something we should develop together. - There are other variations of encryption we still don't support, eg.the"Extensible" encryption, the "RC4 CryptoAPI" encryption, "XORobfuscation",etc. Apache POI would be a good source for those too. It's unclear tomehow widely those are used, and whether they are worth implementing.- It may need to be rearchitected when we add OOXML writing.- A lot of other required cleanups to our code were discovered, willdiscuss those separately.I've squashed all my work into a single commit, so it can be easily cherry-picked to AOO42X and maybe even AOO41X when people are happywithit.Regards Damjan
