Certificate validation error on mac osx pyopenssl (twisted)
Raw
fix-osx-ssl-cert-error.txt
# 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).
