Microsoft RSA key blob

Exchange RSA keys between Microsoft CSP blob format (ExportCspBlob, ImportCspBlob of RSACryptoServiceProvider) and ruby openssl key OpenSSL::PKey::RSA

Create key from blob created by ExportCspBlob

    blob = File.binread 'msblob.bin'

    key = OpenSSL::PKey::RSA.from_mskeyblob blob

Create blob for ExportCspBlob

    key = OpenSSL::PKey::RSA.new 2048

    blob = key.to_mskeyblob
    public_blob = key.to_mskeyblob(include_private: false)

Add this line to your application's Gemfile:

gem 'mskeyblob'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mskeyblob
