libtls needs to be somewhere the mruby compiler can find it.
For example on macOS you need to add the folowing to your build_config.rb after installing it with
brew install libressl
conf.gem mgem: 'mruby-tls' do |spec| spec.cc.include_paths << '/usr/local/opt/libressl/include' spec.linker.library_paths << '/usr/local/opt/libressl/lib' end
By default libtls looks in /etc/ssl/cert.pem for ca certs, you can find how to change that in the examples below.
client = Tls::Client.new client.connect('github.com:443').write("GET / HTTP/1.1\r\nHost: github.com\r\nConnection: close\r\n\r\n") print client.read client.close
Its also possible to connect via service descriptions.
You can also use port numbers as the second Argument.
If your ca certs are in another path.
client = Tls::Client.new(ca_file: '/usr/local/etc/libressl/cert.pem')
If you later want to change a config setting
client.config.ca_file = '/etc/ssl/cert.pem'
You can also create a configuration object to share with several connections.
config = Tls::Config.new # see https://github.com/Asmod4n/mruby-tls/blob/master/mrblib/config.rb for options. client = Tls::Client.new config
You can later on change the configuration object
client.config = config
openssl ecparam -name secp256r1 -genkey -out private-key.pem openssl req -new -x509 -key private-key.pem -out server.pem
tls_server = Tls::Server.new(key_file: 'private-key.pem', cert_file: 'server.pem') tcp_server = TCPServer.new 5000 # requires mruby-socket tcp_client = tcp_server.accept tls_client = tls_server.accept_socket tcp_client.fileno tls_client.write "hallo\n" tls_client.close
Client Connections don't have a configurable config at the moment
The following Errors can be thrown:
SystemCallError # Errno::* Tls::WantPollin # The underlying read file descriptor needs to be readable in order to continue. Tls::WantPollout # The underlying write file descriptor needs to be writeable in order to continue.
This maps the C Api 1:1, to get a overview http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man3/tls_accept_fds.3?query=tls%5finit&sec=3 is a good starting point.
