API

/**
 * shuffles your shift key (optional)
 *  @param {string} str ~ shift key
 **/
atbash.keygen(str)


/**
 *  callback
 *  @param {string} data ~ data to encrypt/decrypt
 *  @param {string} key ~ shift key
 *  @param {boolean} enc ~ true = encrypt | false = decrypt
 *  @param {function} cb ~ callback function(err,data)
 **/
atbash.shift(data, key, enc, cb) //returns callback


/**
 *  sync
 *  @param {string} data ~ data to encrypt/decrypt
 *  @param {string} key ~ shift key
 *  @param {boolean} enc ~ true = encrypt | false = decrypt
 **/
atbash.shiftSync(data, key, enc) //returns a string

/**
 *  promise
 *  @param {string} data ~ data to encrypt/decrypt
 *  @param {string} key ~ shift key
 *  @param {boolean} enc ~ true = encrypt | false = decrypt
 **/
atbash.shiftP(data, key, enc) //returns a promise
