YubiOATH
A mostly-complete Ruby implementation of the YubiOATH applet protocol.
Usage
The YubiOATH class accepts a card, which must respond to #transmit(apdu). See costan/smartcard for more info.
yubioath = YubiOATH.new(card)
yubioath.put(name: 'foo', secret: '123456') # => true
yubioath.calculate(name: 'foo', timestamp: Time.now) # => '237846'
yubioath.put(name: 'bar', secret: '345678') # => true
yubioath.put(name: 'qux', secret: '567890') # => true
yubioath.list.keys # => ['foo', 'bar', 'qux']
yubioath.calculate_all(timestamp: Time.now) # => {'foo' => '234526', 'bar' => '293857', 'qux' => '934856'}
yubioath.delete('qux') # => true
yubioath.list.keys # => ['foo', 'bar']
yubioath.reset # => true
yubioath.list.empty? # => trueInstructions
You can also trigger the instructions by instantiating the relevant class with a card and invoking its #call method.
calculate = YubiOATH::Calculate.new(card)
calculate_all = YubiOATH::CalculateAll.new(card)
delete = YubiOATH::Delete.new(card)
list = YubiOATH::List.new(card)
put = YubiOATH::Put.new(card)
reset = YubiOATH::Reset.new(card)
put.call(name: 'foo', secret: '123456') # => true
calculate.call(name: 'foo', timestamp: Time.now) # => '237846'
put.call(name: 'bar', secret: '345678') # => true
put.call(name: 'qux', secret: '567890') # => true
list.call.keys # => ['foo', 'bar', 'qux']
calculate_all.call(timestamp: Time.now) # => {'foo' => '234526', 'bar' => '293857', 'qux' => '934856'}
delete.call('qux') # => true
list.call.keys # => ['foo', 'bar']
reset.call # => true
list.call.empty? # => true
