Importable implementation of Keybase's Triplesec (symetric encryption) to be run comfortably from ruby and other languages. Raw

// Example usage in ruby:
// key = '1234'
// msg = 'secret message'
// enc = (`coffee -e "t=require('./node/triplesec.coffee');t.enc('#{key}','#{msg}')"`).gsub(/\n/,'')
// dec = (`coffee -e "t=require('./node/triplesec.coffee');t.dec('#{key}','#{enc}')"`).gsub(/\n/,'')
