    When creating an OpenSSL::PKey::RSA object you get an exponent and a modulus that can be used to construct the public and private key. So if I say something like:

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



    which is the exponent I might get a number like this back:

    65537 (the modulus would be a much larger number). What I need to know is, in what form is that number? Hex? Base64? The reason I need to know is because I need to take those parts of the key and place it in an xml formatted field so I can decrypt my data in VB, but VB does not like the decimal representation of that data. Thanks for any and all help,

    puts @key.e.class #=> OpenSSL::BN

    It's just a regular decimal number. It may be a larger decimal number that can be represented in 32 bits though, so you'll likely need to use a big number library for VB, and transport the numbers around as strings.
