TokenChain

Generates a deterministic chain (or sequence) of tokens from a passphrase.

Add this line to your application's Gemfile:

gem 'token_chain'

And then execute:

$ bundle

Or install it yourself as:

$ gem install token_chain

You can create a token chain from a passphrase:

chain = TokenChain.from_passphrase 'the rain in spain'
chain.generate    #=> [first token]
chain.generate(2) #=> [second token, third token]
chain.anchor_code #=> anchor code for this chain, useful for restarting w/out passphrase

Provided you have a chain's anchor code, you can also "restart" a chain without the passphrase:

chain = TokenChain.from_anchor anchor_code
chain.generate #=> [first token]

You can even jumpstart the chain to generate from a previously generated token:

chain = TokenChain.from_anchor anchor_code, second_code
chain.generate #=> [third code]
