I think this is causing failures in some of our tests so this PR reverts the change until we can fix the problem.
The 2nd commit is to keep the change using more idiomatic wording in the changelog for another change that got included in this PR.
* Revert "Use built-in support for OCSP in cryptography >= 2.5 (#6603)"
This reverts commit 2ddaf3db04.
* keep changelog correction
In response to #6594. [Fixes #6594.]
To execute OCSP requests, certbot relies currently on a openssl binary execution. If openssl is not present in the PATH, the OCSP check will be silently ignored. Since version 2.4, cryptography has support for OCSP requests, without the need to have openssl binary available locally.
This PR takes advantage of it, and will use the built-in support of OCSP in cryptography for versions >= 2.4. Otherwise, fallback is done do a direct call to openssl binary, allowing oldest requirements to still work with legacy cryptography versions.
Update: requirement is now cryptography >= 2.5, to avoid to rely on a private method from cryptography.
* Implement logic using cryptography
* Working OSCP using pure cryptography
* Fix openssl usage in unit tests
* Reduce verbosity
* Add tests
* Improve naive skipIf
* Test resiliency
* Update ocsp.py
* Validate OCSP response. Unify OCSP URL get
* Improve resiliency checks, correct lint/mypy
* Improve hash selection
* Fix warnings when calling openssl bin
* Load OCSP tests assets as vectors.

* Revert "Revert "switch signature verification to use pure cryptography (#6000)" (#6074)"
This reverts commit 3cffe1449c.
* Fixes#6073.
This silences the deprecation warnings from cryptography. I looked into only
silencing the cryptography warning specifically in the function, however,
CryptographyDeprecationWarning doesn't seem to be publicly documented, so we
probably shouldn't depend on it.
* switch signature verification to use pure cryptography
On systems that prevent write/execute pages this prevents a segfault
that is caused by pyopenssl creating a dynamic callback in the
verification helper.
* switch to using a verifier for older cryptography releases
also add ec support, test vectors, and a test
* cert signature validation for certificates subcommand + a test
* refactoring validation + adding in a check for making sure that the private key matches the certificate
* adding testing certs
* assertIsNone(x) -> assertEqual(None,x) to unbreak the py2.6 tests
* modifying test_verifu_renewable_cert_failure to hopefully appease python 3 test timeouts
* updating cryptography to be >=1.2 so that we can use verify
* removing unused, old testing certificate
* adding better error handling/logging
* adding test for IOError
* switching to a 2048 bit rsa key
It's relatively finicky to make a CSR appropriate to pass to poll_and_request_issuance. I think most users want to be able to give a list of domains and a private key, and get back a CSR. This branch adds that functionality to crypto_util.
Note that the two new functions take arguments, and return values, as PEM-encoded buffers. This is a departure from some existing ACME interfaces that take PyOpenSSL types. I've discussed with the Certbot team, and we agree that this is broadly the direction the ACME API should take, so that users of the module don't need to import PyOpenSSL themselves, or use its primitives.
* Add make_csr.
* accept privkey
* Tweak API.
* Remove make_csr from certbot package.
* Skip test in older Pythons.
* Move get_Extensions call under protection.
* Remove assertIn because not backwards-compatible.
* Fix encoding, and use PEM.
* Fix test
* Fix tests on py35.
* Fix error in test.
* Make import_csr_file always return PEM.
Also delete get_sans_from_csr (unused) and get_names_from_csr (newly unused).
* Fix function doc.
* Fix indent
* Fix call of obtain_certificate_from_Csr
* lint
* Handle review feedback.
* Fix test.
* Create symlinks at runtime in cli_test.py
* use test_util.vector_path rather than hardcoding path
* Reference #2716 in comment about too many lines in cli.py
