* Revert "Don't save keys/csr on dry run (#4380)"
This reverts commit e034b50363.
* Don't save CSRs and keys during dry run
* Factor out _test_obtain_certificate_common
* Add test_obtain_certificate_dry_run
* Wrap key from make_key in util.Key
* Wrap result from make_csr in util.CSR
* 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
Fixes#4559.
* Update options-ssl-nginx.conf in prepare, if it hasn't been modified.
* add previous options-ssl-nginx.conf hashes
* InstallSslOptionsConfTest
* remove .new file and only print warning once
* save digest to /etc/letsencrypt
* add comment reminding devs to update hashes
* add comment and test for sha256sum
* treat hash file as text file because python3
* move constants and rename hidden digest file
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.
* Standardize arguments name for mode and chmod in the util API
* Handle OpenSSL pem as bytes objects only for Python3 compatibility
* Handle OpenSSL pem as bytes objects only (remaining bits)
* Manipulate bytes objects only when testing PEM-related functions
* Fix argument order when calling util.unique_file
