* Bind a pair of mem functions.
* make these conditional
* do the conditional correctly
* move to the right section
* I'm not saying libressl should be illegal, but it is annoying
* sigh, typo
* first cut at memleak tests. doesn't work
* hack around the previous error, onto the next one
* drop the pointless restoration of the original functions
* Don't try to use the previous malloc functions.
The default malloc is CRYPTO_malloc which calls the custom ptr you provided, so it just recurses forever.

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.

If pyca/cryptography sees any errors on the error stack during its own
initialization it immediately raises InternalError and refuses to
proceed. This was a safety measure since we weren't sure if it was
safe to proceed. However, reality has intervened and we have to
bow to the god of pragmatism and just clear the error queue. In
practice this is safe since we religiously check the error queue
in operation.

* 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
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

* New osrandom_engine in C
Inspired by Python/random.c and the old implementation.
Signed-off-by: Christian Heimes <christian@python.org>
* osrandom_engine
* Fix naming bug caused by search 'n replace mistake
* Make it easier to override osrandom auto-detection
* Add engine ctrl and backend API to get implementation from ENGINE

* Add macOS to spelling list. 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.

* Start of OpenSSL DH backend implementation
* Supporting DH in MultiBackend
* DHBackend has dh_parameters_supported method
* Removed DHParametersWithNumbers and DHPrivateKeyWithNumbers from documentation
* Removed ExchangeContext. exchange is a method of DHPrivateKeyWithSerialization
* PEP8 fixes
* Fixed TestDH.test_bad_tls_exchange
* Fixed generate_private_key reference in dh documentation
* test DH multibackend support
* testing DH coversion to serialized
* Validating that we receive serialized class in test_generate_dh
* Testing DH exchange symmetric key padding
* struct DH is now opaqued
* PEP8 fixes
* Testing load_dh_private_numbers throws ValueError when DH_check fails
* Using openssl_assert
* Passing keywords arguments in DH key exchange example
* test_dh::test_bad_tls_exchange now uses pre calculated parameters
* TestDH - Add test that the computed secret is equivalent to the definition by comparing with secret computed in pure python
* Add missing generator parameter to DHBackend interface docs.
* Include parameter type in DHBackend abc docs.
* Add docs for dh.generate_parameters function
* Remove the dh Numbers section, and move the DHNumbers class docs to where they are first used.
* Add note of big endian byte packing to DH exchange method.
* DH documentation updates.
Add single sentence overview with wikipedia link.
Add paragraph on assembling using Numbers objects.
Add link to backend interface docs.
First section was all indented, I think by mistake.
* Add exchange method to DHPrivateKey abstract base class.
* Small tweaks to DH documentation - remove Provider.
* Add endian to dictionary
* Use utils.int_from_bytes in test_tls_exchange_algorithm
* Removed duplicate line
* Change dh.rst exchange algorithm from doctest to code-block
The example in the Diffie-Hellman exhange algorithm is using
2048 bits key. Generating the parameters of 2048 takes long
time. This caused the automated tests to fail. In order to
pass the tests we change the example to code-block so it
will not run in the doc tests.
* Fix dh docs
* Document the generator in DHBackend relevant methods

* Remove Python OpenSSL locking callback and replace it with one in C
The Python OpenSSL locking callback is unsafe; if GC is triggered
during the callback's invocation, it can result in the callback being
invoked reentrantly, which can lead to deadlocks. This patch replaces
it with one in C that gets built at compile time via cffi along with
the rest of the OpenSSL binding.
* fixes for some issues
* unused
* revert these changes
* these two for good measure
* missing param
* sigh, syntax
* delete tests that assumed an ability to mess with locks
* style fixes
* licensing stuff
* utf8
* Unicode. Huh. What it isn't good for, absolutely nothing.

This patch adds wrapper methods to allow the user to sign and verify a
single message block without having to go through the multi-step
process of creating a signer or verifier, updating it with the one
message, and finalizing the result. This will make signing and
verifying data more user-friendly when only using small messages.
Partial bug #1529
