Current openssl_certificate is mistakenly taking its derivating its
version number from the csr version number.
Thos two fields are completly unrelated and hence the version number of
the certificate should be able to be directly specified (via
selfsigned_version parameter).
* openssl_certificate: Fix parameter assertion in Python3
Parameter assertion in Python3 is broken. pyOpenSSL get_X() functions
returns b'' type string and tries to compare it with '' string, leading
to failure.
The error mentionned above has been fixed by sanitizing the inputs from
a user to the assert only backend.
Also, this error was hidden by the fact that the improper check method
was called in the generate() functions.
* Add simple integration test for openssl_certificate
* remove subject == issuer assertion
* run integration tests only on supported hosts
* change min supported version to 0.15.x
* Add test for more CSR fields
* also convert dict members to bytes
* fix version_compare
* openssl_{csr, certificate}: Fail if pyOpenSSL <= 0.15
Previous 0.13 pyOpenSSL was a C-binding, and required the parameter
passed to add_extention to be in ASN.1. This has changed with the move
to 0.14 and it is now all pythong and string based.
Previous the 0.15 release, the `get_extensions()` method didn't exist,
since the modules rely heavily on it we ensure pyOpenSSL version is at
last 0.15.0.
* check pyopenssl version in openssl_csr integration test
