* Call the functions `box_seal` and `box_seal_open` to match the libsodium names in module `enacl`.
* Fix a bug in the C NIF: We should fail if the input is `<` SEALBYTES but not on `<=` SEALBYTES. The latter made it impossible to encode empty messages.
* Add variants which run directly on the interpreter scheduler for small messages.
Also:
* Provide full EQC functions for the testing purposes. This generated around 13000 random test cases in a 5 minute run, all passing.# Please enter the commit message for your changes. Lines starting
Provide non-dirty-scheduler variants for small strings, accurately bump
reductions for these strings.
While here, provide EQC test cases for the two functions.
If we write
EXP != 0
and EXP is a very large term, it is hard to see what it gets checked against, so we rewrite it as
0 != EXP
so we instanly see what we check against. While here, teset against 0 != crypto_box_afternm(…)
* Generalize binary generation because it is used again and again.
* Use generalized binary generation in the hash functions since they are much faster as generators.
Negative testing means we inject faulty data into the test now and then. When this happens, we make sure the SUT will
return some kind of badarg error for bad arguments. This means we should make sure things actually work out as they should.
As a side-effect, this can also be used to test for memory leaks. If run for a while, it makes sure there are no leaks in the code base,
and it probably also makes sure there are no ways to crash the server by any means of use of these NIFs. As such, it looks like the
NIFs are fairly stable.
