* reverts a change to our exceptions (#3429)Paul Kehrer2017-03-091-5/+3
| | | | | Trying to be too specific about why key loading fails is very difficult when you're using the same logic across DH, EC, RSA, and DSA. This makes it less fancy.
* DH subgroup order (q) (#3369)Aviv Palivoda2017-03-051-3/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Support DH q (subgroup order) * Change RFC5114.txt to NIST format * Add tests for DH q * Update docs for DH q * Fix pep8 * Improve test covergae for DH q * Create _dh_params_dup that copy q if DHparams_dup don't On OpenSSL < 1.0.2 DHparams_dup don't copy q. _dh_params_dup call DHparams_dup and if the version is smaller than 1.0.2 copy q manually * Copy q manually on libressl * Add to test vectors serialized RFC5114 2048 bit DH parameters with 224 bit subgroup * Support serialization of DH with q * Add tests for serialization of DH with q * Support DH serialization with q only if Cryptography_HAS_EVP_PKEY_DHX is true * Raise exception when trying to serialize DH X9.42 when not supported * raise unsupported key type when deserilizing DH X9.42 if not supported * pep8 fixes * Fix test_serialization * Add dhx_serialization_supported method to DHBacked * document q in dh_parameters_supported * Rename dhx_serialization_supported to dh_x942_serialization_supported
* switch the PEM password callback to a C implementation (#3382)Paul Kehrer2017-02-131-15/+24
| | | | | | | | | | | | | | | * switch the PEM password callback to a C implementation Calling from C to Python is fraught with edge cases, especially in subinterpreter land. This commit moves the PEM password callback logic into a small C function and then removes all the infrastructure for the cffi callbacks (as we no longer have any) * review feedback and update tests * rename the struct * aaand one more fix
* enforce password must be bytes when loading PEM/DER asymmetric keys (#3383)Paul Kehrer2017-02-081-1/+1
| | | | | | | | | | * enforce password must be bytes when loading PEM/DER asymmetric keys Previously we were using an ffi.buffer on the Python string, which was allowing text implicitly, but our documentation explicitly requires bytes. * add changelog entry
* add openssl_version_number & doc openssl_version_text (#3329)Paul Kehrer2016-12-211-0/+3
| | | | | | | | | | * add openssl_version_number & doc openssl_version_text fixes #3315 * more docs + actually assert on the test... * text

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * delete the 1.0.0 support * drop the version check * drop the AES-CTR stuff * Update the example * openssl truncates for us now * delete unused test * unused imports * Remove a bunch of conditional bindings for NPN * no more 1.0.0 builders * libressl fix * update the docs * remove dead branches * oops * this is a word, damnit * spelling * try removing this * this test is not needed * unused import
* New osrandom_engine in C (#3229)Christian Heimes2016-12-091-13/+19

Remove dead code from header file. Signed-off-by: Christian Heimes <christian@python.org> * remove CCRandomGenerateBytes path and update getentropy to work on macOS This change allows us to test all the engines in our CI: * getentropy (tested by macOS sierra) * getrandom (tested on several linux builders) * /dev/urandom (tested on FreeBSD, OS X 10.11 and below, & older linux) * CryptGenRandom (tested on windows builders) I also fixed bugs preventing compilation in the getentropy code * getentropy() returns int and is restricted to 256 bytes on macOS, too. Signed-off-by: Christian Heimes <christian@python.org> * add versionadded * Re-add import of os module * Fixes related to Alex's recent review. Signed-off-by: Christian Heimes <christian@python.org> * Add error reporting and fail for EAGAIN Add error reporting strings for various error cases. This gives us much nicer and understandable error messages. SYS_getrandom() EAGAIN is now an error. Cryptography refuses to initialize its osrandom engine when the Kernel's CPRNG hasn't been seeded yet. Signed-off-by: Christian Heimes <christian@python.org>

* Use a series of constants for OpenSSL version checks (#3037)Alex Gaynor2016-07-111-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | * Use a series of constants for OpenSSL version checks. N.B. I removed several qualifiers that were being used to express beta vs. release in OpenSSL version numbers. Reviewers please look closely! * Convert some python as well, also add the file * flake8 * Simplify code, remove functionality that can be expressed more simply * clean up the tests as well * more constants * wrap long lines * reflect feedback * unused * add this back?

* Replacing test_osrandom_engine_is_default. (#2905)Andreas Moser2016-05-291-0/+12
| | | | | | | | | | | | | | | | | | | * Removing test_osrandom_engine_is_default. test_osrandom_engine_is_default depends on having a valid sys.executable. This attribute is not always set (see https://docs.python.org/2/library/sys.html#sys.executable ) so, in some environments, this test fails. I moved the functionality of the test into the setup and teardown methods so the correct behavior is still tested. * Fixing some style issues. * Removing an unnecessary newline. * Putting back the test. * Moving the assert from teardown to setup.

| * move urandom engine testPaul Kehrer2015-08-011-0/+27
| | | | | | | | | | | | | | | | | | | | This test was in the bindings dir, which is incorrect. We do not set the urandom engine to default unless the openssl backend is loaded. The reason the test wasn't failing (even in the random test case) is that the backends are loaded during pytest_generate_tests by a call to _available_backends. So no matter what order it occurred in the engine was already set to default. I discovered this when I tried to run the test_openssl.py bindings tests directly via pytest. Hooray global state.
