  * 
  * @param string $input    Input data to encrypt
  * @param string $password Encryption/decryption key to use on input
  * @param string $algo     Hashing algo to generate keystream
  * 
  * @return string

  * 
  * @param string $cyphertext Cypher text to decrypt
  * @param string $password   Password that should be used to decrypt input data
  * @param int    $cost       Number of HMAC iterations to perform on key
  * @param string $cipher     Mcrypt cipher
  * @param string $mode       Mcrypt mode
  * @param string $algo       Hashing algorithm to use for internal operations
  * 
  * @return string|boolean Returns false on checksum validation failure
