Constructor Details

#initialize(token, session = nil) ⇒ Tokenator

A bit clunky but useful for testing token decomposition. If you provide a test session then the config values there will be used so that decryption will function without @Pay’s private key.

Class Method Details

.find_by_checksum(token) ⇒ Object

Check and make sure we haven’t seen this token before. NOTE: This is really for internal use by @Pay.

def find_by_checksum(token)
  checksum = Digest::SHA1.hexdigest(token)

  SecurityKey.find_by_encoded_key(checksum) || ValidationToken.find_by_encoded_key(checksum)
end

.token_version(token) ⇒ Object

Get the version of the given token.

def token_version(token)
  token.scan('-').empty? ? 0 : unpack_version(token.split('-')[0])
end

Instance Method Details

#body(key) ⇒ Object

Here we parse the body of the token. All the useful shit comes out of this.

# File 'lib/atpay/tokenator.rb', line 71

def body(key)
  payload(nonce, key, @token)
  part_out_payload
end

#browser_data(key) ⇒ Object

With a site token you want to call this after header. It will pull the ip address and header sha out of the token.

def browser_data(key)
  length = @token.slice!(0, 4).unpack("l>")[0]
  @site_frame = boxer(key).open(nonce, @token.slice!(0, length))

  length = @token.slice!(0, 4).unpack("l>")[0]
  @ip = @token.slice!(0, length)
end

#header ⇒ Object

We want to pull the header out of the token. This means we grab the nonce and the partner id from the token. The version frame should be removed before calling header.
