there is something wrong with encoding which i don't have time to search and figure it out
size goes from 3-4 mb to 8 mb after decryption
and whenever i decrypt it with other tool i find it fully functional (no idea what the fuck happens)
fix it then it's your's
please bother to lemme know what was wrong with the encoding
here is some codes and find the whole project in attachments

currently the editing of items is fully functional , use any other external tool to encrypt / decrypt
and yes i know that isn't the best way to code this shit
