HI, When compiling the open-source software cryptopp (https://www.cryptopp.com/#download <https://www.cryptopp.com/#download>) version 5.6.4 I found a strange issue with the IR generated. The issue only appears when compiling with -O2 optimisation in the integer.cpp file (the function is _ZN8CryptoPPrsERNSt3__113basic_istreamIcNS0_11char_trait...

Hi Everyone, We caught a report for a failed self test when using Clang 5.0 and 6.0 with -DDEBUG and -O1 (i.e., a "debug build"). The code is question is located at https://github.com/weidai11/cryptopp/blob/master/cham-simd.cpp . It is the SSSE3 code path for CHAM64. Other optimizations levels are OK for Clang. GCC, ICC and MSVC are OK. The code is valgrind, Sanitizer, Coverity and Enterprise Analysis clean. An objdump is available at https://pastebin.com/TAKH4eur but it is not very helpful to...

We have code that processes a buffer in the forward or backwards direction. It looks similar to the following (https://github.com/weidai11/cryptopp/blob/master/adv-simd.h#L1138): uint8_t * ptr = ... size_t len = ... size_t inc = 16; if (flags & REVERSE_DIRECTION) { ptr += len - inc; inc = 0-inc; } while (len > 16) { // process blocks ptr += inc; len -= 16; } Clang 5.0 and UBsan is producing findings (https://tra...

...not, I'm interested in what decisions have been made with respect to these lists. Speed may be a consideration; MD5 is "faster"[2] than any of the SHA- algorithms. Maximum compatability, possibly. Anything else? [1]: http://csrc.nist.gov/groups/ST/hash/policy.html [2]: http://www.cryptopp.com/benchmarks.html

I need to use a cryptography library extension for C/C++ and I'd like to know if anyone can tell me wich one on ports collection is better (the most complete and "easy" to use). Is there anyway to use MIRACL on FreeBSD(and how)?

Hi Everyone, I'm having trouble figuring out a compile failure on ppc64le. The failure is at https://travis-ci.org/noloader/cryptopp-autotools/jobs/602187190 .

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the
