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

triplesec.coffee

module = do ->
  enc: (key_str, pt1_str) ->
    key = new Buffer key_str
    pt1 = new Buffer pt1_str
    {encrypt} = require 'triplesec'
    encrypt { key, data : pt1 }, (err, ciphertext) ->
      console.log ciphertext.toString('base64')

  dec: (key_str, ciphertext_str) ->
    key = new Buffer key_str
    ciphertext = new Buffer ciphertext_str, 'base64'
    {decrypt} = require 'triplesec'
    decrypt { key, data : ciphertext }, (err, pt2) ->
      if !!pt2
        console.log pt2.toString('utf8')
      else
        console.log "error"

exports.enc = module.enc
exports.dec = module.dec

# 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/,'')
