ADDENDUM

Please redownload the files from the repository and re-encrypt your password, I did some important changes:

Increase encryption strength against bruteforce attacks by hashing the password with high iterations. The encryption/decryption now takes ~2 seconds instead of a few milliseconds, which makes bruteforcing harder. Thanks to @therealwolf for the tip and discussion about it.

Cleanup comments
