how to convert rsa key to json

[Raphaël Jadot]

Hello,

I try to follow the documentation for implementing my own IdP, but i
fail in generating a correct browserid file

I made a script (deftojson2) following this document

https://github.com/mozilla/browserid/blob/dev/docs/PRIMARY_PROTOCOL.md
(6.1 Public Key Format)

but while executing the script with "ruby deftojson2" , i've got

-
deftojson2:1:in `<main>': uninitialized constant OpenSSL (NameError)
-


So i added

-
require 'openssl'
-


and I've got

-
deftojson2:4:in `<main>': undefined method `to_json' for #<Hash:0x9ac22f0> (NoMethodError)
-


I tried another script found on the web

-
require 'openssl'
privkey = OpenSSL::PKey::RSA.new(2048)
pubkey = privkey.public_key

# Return BrowserID Identity JSON
def to_json
{
"public-key" => { "algorithm"=> "RS", "n" => public_key.n.to_s, "e" => public_key.e.to_s },
"authentication" => "/sign_in",
"provisioning" => "/provision"
}.to_json
end
-


but I have no output at all.

I'm not a ruby user, I'd be glad if someone can tell me what I'm doing
wrong :)
