| # When you get an error like | |
| # ('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed') | |
| # when using twisted, autobahn, etc... | |
| # on osx | |
| # than you may have to update your openssl | |
| # Do this by using brew: | |
| # (install brew) | |
| brew update | |
| brew install openssl | |
| brew link --force openssl | |
| sudo mv /usr/bin/openssl /usr/bin/openssl_backup | |
| sudo ln -s /usr/local/Cellar/openssl/1.0.1g/bin/openssl /usr/bin/openssl | |
| # now a 'openssl version' should at least output OpenSSL 1.0.2d |

You don't need to update your OpenSSL binary; you just need to have trust roots installed in the Homebrew standard location (which Cryptography, and therefore pyOpenSSL, is built against).
