- This is a quick test intended to detect major errors such as the library being
- miscompiled and segfaulting or returning incorrect answers. We've had problems
- of that kind many times, thus justifying running this self-test on import.
- This idea was suggested to me by the second edition of "Practical
- Cryptography" by Ferguson, Schneier, and Kohno.
- This test was copied from pycryptopp/test/test_sha256.py on 2010-09-04.
-
- This test takes up to 1.5 milliseconds on a VirtualBox instance on
- my Macbook Pro (fast 64-bit Intel dual-core).
-
- Test that updating a hasher with various sized inputs yields
- the expected answer. This is somewhat redundant with
- test_chunksize(), but that's okay. This one exercises some
- slightly different situations (such as finalizing a hash after
- different length inputs.) This one is recursive so that there
- is a single fixed result that we expect.
