CyberplatPKI

CyberplatPKI 1.0 is an FFI binding for signing Cyberplat requests. It includes both Linux and Windows versions of Cyberplat-provided library as well as the necessary wrapping code. Note that this version only works on 32-bit Linux and Windows.

CyberplatPKI 2.0 is a pure-Ruby reimplementation of the reverse-engineered signing algorithm. It should be completely compatible with the vendor-provided library. This version works everywhere.

Select the variant you'd like to install with the version specification. gem 'cyberplat_pki', '~> 1.0' requests the FFI version, and gem 'cyberplat_pki', '~> 2.0' requests the pure-Ruby one.

Installation

Add this line to your application's Gemfile:

gem 'cyberplat_pki'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cyberplat_pki

Usage

To sign:

privkey_serialized = File.read("private.key")
privkey = CyberplatPKI::Key.new_private(privkey_serialized, 'passphrase')

signed_data = privkey.sign(data)

To verify:

pubkey_serialized = File.read("public.key")
pubkey = CyberplatPKI::Key.new_public(pubkey_serialized, 12345) # serial = 12345

pubkey.verify(signed_data) # => true

Note that the library uses Windows line endings (\r\n) internally. You must not touch those, or the library will fail. Treat the signed data as binary, or make sure to restore the expected line endings.
