Failing spec Acme::Client::CertificateRequest assigns the public key (FAILED - 1)

[weppos]

I can't get the current test suite to work. I keep getting an error on the following spec:

Acme::Client::CertificateRequest
  assigns the public key (FAILED - 1)

Failures:

  1) Acme::Client::CertificateRequest assigns the public key
     Failure/Error: expect(request.csr.public_key.to_der).to eq(public_key_to_der(test_key))

Interestingly enough, the DER conversion seems to be causing the problem. I compared the PEM and it worked, but the DER does not.

(byebug) public_key_from_private(request.csr.public_key).to_pem == public_key_from_private(test_key).to_pem
true
(byebug) request.csr.public_key.to_der == public_key_to_der(test_key)
false

Anyone else is having the same issue?

I'm seeing this too. I think this isn't visible to the devs, since the tests run on Travis with OpenSSL 1.0.2g 1 Mar 2016, and (I suspect) previous version of OpenSSL would replace the private key in a signing request with the public key as a side-effect of signing.

I think https://github.com/unixcharles/acme-client/pull/111/files/a988895a70da676ab3c818c096c89ee54f95c899 is the root cause, because when I altered the test to compare request.csr.public_key.to_der with test_key.to_der, it passed.

#189 fix this. I'm giving up on fully understanding OpenSSL at this point.

Also switched to comparing in PEM. It make the diff much more obvious.
