The file crypto_driver.h was not using the header guard style as other PSA
Crypto header files. Remove the `__` prefix and suffix. Use C-style
comments for the end-of-guard comment.
The driver model's "encrypt or decrypt" type, encrypt_or_decrypt_t, is
publicly exposed and needs to have a `psa_` prefix in order to properly
communicate that it is part of the PSA driver model.
The `pcd_` prefix is ambiguous and does not make it clear that the types
and symbols are standardized by PSA. Replace `pcd_` with a prefix that can
be shared with all PSA drivers, `psa_drv_`.
"Driver APIs" can be interpreted to mean APIs used when you want to write a
driver, not the set of functions you implement to make a driver. See
https://www.kernel.org/doc/html/latest/driver-api/index.html "The kernel
offers a wide variety of interfaces to support the development of device
drivers."
As such, we are renaming "Driver API" to "Driver Model" and updating our
work so far to reflect this change.
Key derivation test now uses an indirect way to test generator validity
as the direct way previously used isn't compatible with the PSA IPC
implementation. Additional bad path test for the generator added
to check basic bad-path scenarios.
Use `( x >> y ) & z` instead of `x >> y & z`. Both are equivalent
by operator precedence, but the former is more readable and the
commonly used idiom in the library.
Correct a typo in an AES XTS implementation comment where the relevant
NIST standard was incorrectly referred to as NIST 80-38E instead of NIST
800-38E.
It is inaccurate to call a data unit a "sector". A disk sector is a
common use case for the data unit, but there exist other types of data
units that are not sectors.
snprintf was only added in Visual Studio 2015. This adds support
for building using Visual Studio versions prior to 2015.
This implementation of snprintf has been taken from platform.c
In /crypto/.gitignore, list files that are generated by a build done
under /crypto/. In the outer /.gitignore, list files under /crypto/
only if they are created by the export process.
This commit slightly refines both lists and adds some build products
to /crypto/.gitignore.
It turns out that in some environments MinGW esposes a non-conforming
(v)snprintf behavior despite the tests against the MSVC runtime pass.
Therefore it has been included in the "non-conforming" scope alongide
older MSVC rungime environments.
