It's part of the ASN feature but since it's also used by the RSA
binding this function must also be part of the library when only
the RSA feature is selected.
The definitions for the following functions are not always available
when wolfSSL is configured to only contain a minimum of functionality:
- wc_GetPkcs8TraditionalOffset (only with ASN, which is required for
RSA)
- wc_PemToDer (only when KEYGEN is enabled)
- wc_DerToPemEx (only when KEYGEN is enabled)
This change allows for building the Python wrapper when ASN and RSA
are both disabled.
`defines` was a string instead of a list of strings. This made it
impossible to build a wrapper with a configuration in which AES-CBC
is disabled, because `'#define NO_AES' in defines` matched also
when the header contains `#define NO_AES_CBC`. With `defines` being
a list the code actually does what you think it does.
- Move _build_ffi.py to scripts/build_ffi.py. Do as little in the global
namespace of the script as possible by putting functionality into functions,
including a new main function.
- Improve feature detection by allowing user_settings.h in addition to
options.h. This is particularly useful on Windows.
- Add the windows directory. This contains subdirectories non_fips and
fips_ready, which each have a user_settings.h. The non_fips user_settings.h is
used by the build script to build on Windows with CMake, when not using
USE_LOCAL_WOLFSSL. The fips_ready user_settings.h is an example user_settings.h
that works with our FIPS Ready code and wolfcrypt-py.
- Improve Windows support. This commit modifies the way we build wolfSSL for
wolfcrypt-py on Windows. Instead of using CMake directly, we use it with
user_settings.h. This is typically how Windows users are building wolfSSL, and
it gets around some shortcoming of wolfSSL's CMake support (e.g. not all
required features are supported). Additionally, USE_LOCAL_WOLFSSL now works
properly on Windows. When using USE_LOCAL_WOLFSSL, it should point to a wolfSSL
source code directory. This works for FIPS bundles, too. Finally, for FIPS on
Windows, we only support DLL builds. The CFFI library (.pyd extension) requires
this DLL to work. build_ffi.py detects this scenario and copies the .dll into
the wolfcrypt package directory. I've modified setup.py to distribute the
.dll with the package.
- Add some missing FIPS gates. Testing against FIPS v2 triggered some errors.
Those are fixed in this commit.
