    Note to reviewers: Let me know if this cleanup is better placed somewhere else (i.e. outside of OldDecrypt(…) to avoid doing it more than once). One alternative would be to put it in ~BasicTestingSetup(), but then it’ll run for unrelated tests as well.

    I’m not sure I understand this. OpenSSL API is confusing, where is the symmetric “create” for this remove/free? Surprised that this needs ERR_* just to deallocate a structure that comes out of the blue. Is this related to cleanup in ~CInit() in util.cpp?
    practicalswift commented at 9:02 pm on August 10, 2017:

    Yes, the OpenSSL API is full of surprises! :-)

    This is my understanding:

    OldDecrypt(…) (in crypto_tests.cpp) calls OpenSSL’s EVP_DecryptFinal_ex(…).

    If EVP_DecryptFinal_ex(…) encounters any errors then EVPerr(…) is called.

    EVPerr(…) is defined as:

    0#define EVPerr(f,r)  ERR_PUT_error(ERR_LIB_EVP,(f),(r),OPENSSL_FILE,OPENSSL_LINE)

    ERR_PUT_error(…) stores stores the errors in a thread local error queue for which the allocations are made using OPENSSL_zalloc(…) in ERR_get_state(…).

    practicalswift commented at 9:47 pm on August 10, 2017:
    ERR_remove_thread_state(nullptr) must be run for each thread as I’ve understood it, so I don’t think putting it in ~CInit() would be the right thing to do?
  5. gmaxwell commented at 10:23 pm on August 10, 2017: contributor
    Alternatively we could drop this test. I think it’s served its purpose now (our implementation is fine even across many systems) and hopefully OpenSSL will not be required to build without the GUI in 0.16.

    I’d rather just get rid of OpenSSL… we’re very close to the point that it doesn’t have much added benefit over our internal RNG.
  8. practicalswift commented at 8:08 am on August 11, 2017: contributor

    @gmaxwell I’ve now added a commit that removes Old{SetKeyFromPassphrase,Encrypt,Decrypt}. Is that in accordance with your suggestion? :-)

    Let me know if it looks good and I’ll squash it into one commit.

  18. theuni commented at 10:11 pm on August 16, 2017: member

    I have no issue with removing the old comparisons, as I think it’s safe to say by now that our implementation lines up well enough with the old openssl one.

    However, I don’t think it’d be a terrible idea to snapshot our current implementation and compare against that. That way future changes are checked against something.

    I suppose that’s really not necessary until those future changes exist, though.

    utACK.
