* Make Montgomery reduction constant time.Jack Lloyd2015-10-241-71/+48
| | | | | | | | | | | | | | It was already close, but the carry loop would break early and selecting which value to copy out was indexed on the borrow bit. Have the carry loop run through, and add a const-time conditional copy operation and use that to copy the output. Convert ct_utils to CT namespace. Templatize the utils, which I was hesitant to do initially but is pretty useful when dealing with arbitrary word sizes. Remove the poison macros, replace with inline funcs which reads cleaner at the call site.
* Make OpenSSL ECDSA and RSA request only until they can be testedJack Lloyd2015-10-191-2/+2

* Break up openssl providerJack Lloyd2015-10-192-0/+51
| | | | | | For RSA, RC4, and ECDSA put the openssl versions in the same directory as the base version. They just rely on a macro check for the openssl module to test for the desire to use OpenSSL.
* Cleanups in ct and oaepJack Lloyd2015-10-171-87/+12

* Make PKCS #1 and OAEP decoding constant time to avoid oracle attacksJack Lloyd2015-10-164-125/+209

| * Initial support for 64 bit ARMDaniel Seither2015-10-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for 64 bit ARM cores as used in many high-end phones such as all iPhones beginning with the 5s. While these newer phones still run 32 bit ARM code, Apple doesn't allow apps to be submitted to the app store if they don't provide a 64 bit build. This commit adds a new arm64 arch and renames arm to arm32 to stay consistent with the other architectures. The name arm can still be used for configuring because it has been added as an alias for arm32. Additionally, the one piece of ARM inline assembly that can be found in Botan doesn't work on 64 bit ARM, so I use the solution that has been proposed in #180: Use __builtin_bswap32 instead of inline assembly.
* | Move DataSource to utils and rewrite PEM encoding to avoid filtersJack Lloyd2015-10-143-0/+393
|/ | | | | Removes filters as as an internal dependency pretty much entirely (outside of some dusty corners in misc).
* Avoid concatination of charsSimon Warta2015-09-221-1/+1
| | | | | | | Ever tried? auto str = "some long string"; auto str2 = str + '\n'; It's not with the brainfuck finding the bug.

* Move check for SIMD instructions to CPUIDJack Lloyd2015-09-215-6/+15
| | | | | | Avoids needing to include simd_32 to see if SIMD is disabled. This had caused a build break on Linux x86-32 as SSE2 must be enabled on a per-file basis.

* Avoid integer overlow in string->uint32 converterSimon Warta2015-08-101-3/+16
| | | | | | | On systems where unsigned long is uint64 (typically 64 bit systems), a string containing a number greater than 2^32-1 was sucessfully converted to a uint64 and than reduced to uint32, causing an overflow. E.g. to_u32bit("4294967296") was 0 and to_u32bit("4294967297") was 1.

| | | | | | | | | | | | | | | Convert all uses of Algorithm_Factory and the engines to using Algo_Registry The shared pool of entropy sources remains but is moved to EntropySource. With that and few remaining initializations (default OIDs and aliases) moved elsewhere, the global state is empty and init and shutdown are no-ops. Remove almost all of the headers and code for handling the global state, except LibraryInitializer which remains as a compatability stub. Update seeding for blinding so only one hacky almost-global RNG instance needs to be setup instead of across all pubkey uses (it uses either the system RNG or an AutoSeeded_RNG if the system RNG is not available).

| | | | | | | | | | | | | | | | | Transforms and BlockCiphers. Registration for all types is done at startup but is very cheap as just a std::function and a std::map entry are created, no actual objects are created until needed. This is a huge improvement over Algorithm_Factory which used T::clone() as the function and thus kept a prototype object of each type in memory. Replace existing lookup mechanisms for ciphers, AEADs, and compression to use the transform lookup. The existing Engine framework remains in place for BlockCipher, but the engines now just call to the registry instead of having hardcoded lookups. s/Transformation/Transform/ with typedefs for compatability. Remove lib/selftest code (for runtime selftesting): not the right approach.
