lib/crypto: tests: Add SHA3 kunit tests
Add a SHA3 kunit test suite, providing the following:
(*) A simple test of each of SHA3-224, SHA3-256, SHA3-384, SHA3-512,
SHAKE128 and SHAKE256.
(*) NIST 0- and 1600-bit test vectors for SHAKE128 and SHAKE256.
(*) Output tiling (multiple squeezing) tests for SHAKE256.
(*) Standard hash template test for SHA3-256. To make this possible,
gen-hash-testvecs.py is modified to support sha3-256.
(*) Standard benchmark test for SHA3-256.
[EB: dropped some unnecessary changes to gen-hash-testvecs.py, moved
addition of Testing section in doc file into this commit, and
other small cleanups]

Testing
|
||||
=======
|
||||
|
||||
To test the SHA-3 code, use sha3_kunit (CONFIG_CRYPTO_LIB_SHA3_KUNIT_TEST).
|
||||
|
||||
Since the SHA-3 algorithms are FIPS-approved, when the kernel is booted in FIPS
|
||||
mode the SHA-3 library also performs a simple self-test. This is purely to meet
|
||||
a FIPS requirement. Normal testing done by kernel developers and integrators
|
||||
should use the much more comprehensive KUnit test suite instead.
