mruby-polarssl

Description

With PolarSSL for mruby, you can use SSL and cryptography functionality from PolarSSL in your mruby programs.

Features

Set up encrypted SSL connections.

Install

add conf.gem line to build_config.rb

MRuby::Build.new do |conf|

    # ... (snip) ...

    conf.gem :git => 'https://github.com/luisbebop/mruby-polarssl.git'
end

Test

ruby run_test.rb test

Usage

socket = TCPSocket.new('polarssl.org', 443)

entropy = PolarSSL::Entropy.new
ctr_drbg = PolarSSL::CtrDrbg.new(entropy)

ssl = PolarSSL::SSL.new
ssl.set_endpoint(PolarSSL::SSL::SSL_IS_CLIENT)
ssl.set_authmode(PolarSSL::SSL::SSL_VERIFY_NONE)
ssl.set_rng(ctr_drbg)
ssl.set_socket(socket)

ssl.handshake

ssl.write("GET / HTTP/1.0\r\nHost: polarssl.org\r\n\r\n")

response = ""
while chunk = ssl.read(1024)
  response << chunk
end

puts response

ssl.close_notify

socket.close

ssl.close

Encrypting data

The PolarSSL::Cipher class lets you encrypt data with a wide range of encryption standards DES-CBC, DES-ECB, DES3-CBC and DES3-ECB.

This sample encrypts a given plaintext with DES-ECB:

cipher = PolarSSL::Cipher.new("DES-ECB")
cipher.encrypt
cipher.key = "0123456789ABCDEF"
cipher.update("1111111111111111")
# => "17668DFC7292532D"
