lib/crypto: tests: Add KUnit tests for BLAKE2s

2025-08-29T16:50:19+00:00

Add a KUnit test suite for BLAKE2s. Most of the core test logic is in the previously-added hash-test-template.h. This commit just adds the actual KUnit suite, commits the generated test vectors to the tree so that gen-hash-testvecs.py won't have to be run at build time, and adds a few BLAKE2s-specific test cases. This is the replacement for blake2s-selftest, which an earlier commit removed. Improvements over blake2s-selftest include integration with KUnit, more comprehensive test cases, and support for benchmarking.

lib/crypto: tests: Add KUnit tests for Poly1305

2025-07-14T18:29:36+00:00

Add a KUnit test suite for the Poly1305 functions. Most of its test cases are instantiated from hash-test-template.h, which is also used by the SHA-2 tests. A couple additional test cases are also included to test edge cases specific to Poly1305.

lib/crypto: tests: Add hash-test-template.h and gen-hash-testvecs.py

2025-07-14T18:29:36+00:00

Add hash-test-template.h which generates the following KUnit test cases for hash functions: test_hash_test_vectors test_hash_all_lens_up_to_4096 test_hash_incremental_updates test_hash_buffer_overruns test_hash_overlaps test_hash_alignment_consistency test_hash_ctx_zeroization test_hash_interrupt_context_1 test_hash_interrupt_context_2 test_hmac (when HMAC is supported) benchmark_hash (when CONFIG_CRYPTO_LIB_BENCHMARK=y) The initial use cases for this will be sha224_kunit, sha256_kunit, sha384_kunit, sha512_kunit, and poly1305_kunit. Add a Python script gen-hash-testvecs.py which generates the test vectors required by test_hash_test_vectors, test_hash_all_lens_up_to_4096, and test_hmac.
