If you intend to use the source file as your back-up (instead of saving the resulting paper wallet or private key) keep in mind any changes to the file (INCLUDING META DATA) will result in a different key pair.
Generating keys from digital files is not a viable short or long-term solution for storing ILCOIN. The author of this project is not held responsible for any lost or stolen ILCOIN. Please USE AT YOUR OWN RISK.
