* Clean up handling of POWER ISA extensionsJack Lloyd2019-12-121-0/+4
| | | | See #2226
* Fix Windows linking to consistently use .lib suffix as requiredJack Lloyd2019-12-061-1/+1
| | | | | | Also fix the zlib basename for Windows. Resolves #2210
* Enable SSE2 for RDSEEDJack Lloyd2019-10-091-0/+1
| | | | Fixes #2139
* Use inline asm to avoid GCC bug. Handle RNG failureJack Lloyd2019-08-272-13/+42
|
* Add support for POWER9 DARN RNGJack Lloyd2019-08-274-0/+81
|
* Use RDRAND in such a way that an internal reseed is performedJack Lloyd2019-08-162-28/+93
| | | | | | At least according to Intel's docs. Closes #447
* Fix include for getentropyJack Lloyd2019-07-041-3/+3
| | | | Everyone but BSDs puts it in sys/random.h
* Make the ISA list a listJack Lloyd2019-04-171-1/+3
|
* Rename 'darwin' target to 'macos'Jack Lloyd2019-03-271-1/+1
| | | | | Both because that's the more common term, and because iOS/watchOS also uses the Darwin kernel, but we have a distinct target for mobile.
* Make exceptions easier to translate to error codesJack Lloyd2018-11-231-3/+2
| | | | | | | | | | | Avoid throwing base Botan::Exception type, as it is difficult to determine what the error is in that case. Add Exception::error_code and Exception::error_type which allows (for error code) more information about the error and (for error type) allows knowing the error type without requiring a sequence of catches. See GH #1742
* Add OS::running_in_privileged_stateJack Lloyd2018-09-271-1/+2
| | | | | | | | Avoid any getenv toggles or reading /proc if we are setuid/setgid. It is possible there is or will someday be some file in /proc that is world-readable, but if read by a privileged user causes some side effect.
* Remove Darwin SecRandomCopyBytesJack Lloyd2018-09-044-85/+0
| | | | | It is the same RNG as arc4random and /dev/urandom. And arc4random seems to be working well for iOS and macOS.
* Expose RDRAND RNG through FFIJack Lloyd2018-08-132-4/+5

* Add a warning about win32 stats making antivirus unhappy [ci skip]Jack Lloyd2018-06-251-0/+4

| * Test OS features by the feature vs the OS nameJack Lloyd2017-12-305-41/+15

* | Remove needless <arch> blocks for RDRAND/RDSEEDJack Lloyd2018-01-041-5/+0
|/ | | | These were already implicit due to requiring the relevant ISA
* Use a better name for the entropy source that reads the system RNGJack Lloyd2017-12-231-1/+1
| | | | Now the value round trips with Entropy_Source::create
* FreeBSD removed support for proc filesystem a while agoJack Lloyd2017-12-231-1/+0

* Avoid uninitialized param warningJack Lloyd2017-12-231-0/+1

* Break out of Win32 entropy poll as soon as entropy goal is reached.Jack Lloyd2017-12-221-7/+15
| | | | | | Rather than running over the entire heap list which may be long. Fixes #1369
* Drop IRIX supportJack Lloyd2017-12-132-2/+0
| | | | | | It turns out that GCC dropped support for IRIX in 4.8, so likely there was never even a C++11 compiler that could have been used to compile 2.x in any case.
* Avoid empty methods, use =default or add a commentJack Lloyd2017-10-031-5/+3

* Apply final annotations to the library alsoJack Lloyd2017-09-222-2/+2
| | | | | Done by a perl script which converted all classes to final, followed by selective reversion where it caused compilation failures.
* Header file cleanupsJack Lloyd2017-09-211-1/+0
| | | | Some help from include-what-you-use
* Clean up header includesJack Lloyd2017-09-212-2/+0
| | | | | | | Avoid including build.h or assert.h directly, instead always take them though types.h Avoid math.h in favor of cmath
* Change header guard format to BOTAN_FOO_H_Jack Lloyd2017-09-208-16/+16
| | | | | | ISO C++ reserves names with double underscores in them Closes #512
* Add API stability annotations.Jack Lloyd2017-09-191-2/+2
| | | | | Defined in build.h, all equal to BOTAN_DLL so ties into existing system for exporting symbols.
* Define macro so windows.h doesn't include winsock.hJack Lloyd2017-09-031-0/+2
| | | | Ugh Windows headers y u so nasty.
* Refactor RNGs to support Windows PhoneJack Lloyd2017-09-024-183/+45
| | | | | | | | | | | | | | | | | | | This OS has its own crypto API and does not support CryptGenRandom. Splits System_RNG_Impl into distinct declarations one per implementation type. Easier to read now that we are up to 4 distinct versions. Removes the CryptoAPI entropy source, and replaces it with an entropy source that calls the system RNG. This is nominally a bit less flexible in that the entropy source allowed polling multiple providers (though we didn't actually make use of that). Plus side is it works on all systems. Currently the dev_random entropy source is still there because we do actually use it to poll both /dev/random and /dev/urandom, and it might be useful (on certain systems) to also poll a HW RNG, which are often assigned their own device node. This could debatably also be removed in favor of just reading the system RNG.
* Fix missing virtual destructor on CSP_HandleJack Lloyd2017-08-312-2/+3
| | | | Caught by GCC cross compiling. Also fix a couple 0-as-null warnings.
* Fix for amalgamation build on WindowsRené Korthaus2017-08-041-0/+1

* Remove low compiler version restrictionsSimon Warta2017-07-311-3/+3
| | | | | | All minimum compiler versions in rdseed are less or equal the minimum compiler version for the Botan 2.x branch. Remove those explicit restrictions to allow users with unknown cc_version to compile rdseed
* Fixes for MSVC version detectionJack Lloyd2017-05-191-1/+1
| | | | | See comments in https://github.com/randombit/botan/commit/7f019174bfcf3c2b31bda74fe40ce35727db1cef
* Let modules specify minimum compiler version, add runtime compiler version checkJack Lloyd2017-05-181-3/+3
| | | | | | | | | | | | | This comes up recently to support CPU extensions by Intel (#826) and ARM (#844) since the intrinsic functions were only added in compiler versions more recent than the minimums we generally support, but might actually be useful for all kinds of things in the future since one can add a (new, otherwise optional) C++14 or C++17 module in 2.x branch while continuing to support the current set of supported compiler versions for the main library functionality. Uses RDSEED as the test case, to ensure version detection/comparisons work on all platforms.
* Content:Tomasz Frydrych2017-04-031-1/+1
| | | | | | | | | * fixes for deprecated constructions in c++11 and later (explicit rule of 3/5 or implicit rule of 0 and other violations) * `default` specifier instead of `{}` in some places(probably all) * removal of unreachable code (for example `return` after `throw`) * removal of compilation unit only visible, but not used functions * fix for `throw()` specifier - used instead `BOTAN_NOEXCEPT` * removed not needed semicolons
* Remove "Dirty hack" for multiple defines in lex_me_harder()Simon Warta2017-04-029-9/+27

* Always poll 256 bytes from Getentropy.Alexander Bluhm2017-03-301-3/+4
| | | | | | The OpenBSD system limit for getentropy(2) is 256 bytes. It does not make sense to use the BOTAN_SYSTEM_RNG_POLL_REQUEST define here. As it is only used in one place, another define would be overkill.
* Disable entropy proc_walk on OpenBSD.Alexander Bluhm2017-03-301-1/+0
| | | | | The /proc file system was disabled for years. With OpenBSD 5.7 the implementation has been removed from the kernel sources.
* Use getentropy(2) as random source.Alexander Bluhm2017-03-294-0/+78
| | | | | | | | Gather entropy from system call getentropy(2). This is available since in OpenBSD 5.6 and Solaris 11.3. It can provide up to 256 bytes entropy from the kernel without blocking. As a system call it does not need a file descriptor and works in chroot(2) environments without device nodes.
