It looks like crypt.crypt('', crypt.METHOD_CRYPT) returns None. This method must be excluded from crypt.methods. Attached patch should fix the issue, but I didn't try it on OpenBSD. Python 3.4-3.6 is affect, Python 2.7 is not affect (crypt.methods was introduced in Python 3). http://buildbot.python.org/all/builders/x86%20OpenBSD%203.5/builds/186/steps/test/logs/stdio test_saltedcrypt (test.test_crypt.CryptTestCase) ...

fixes test_crypt in 3.7. In other versions the test should be just skipped on OpenBSD. Blowfish is the only method supported on OpenBSD, but it was not supported by the Python's crypt module.
