Modify an Open Source Program to Securely Store Passwords There is an open source program I use that saves usernames and passwords in 3 plain text xml files. This is obviously insecure. I would like someone to modify this program so that when the program first starts a master password must be entered. Then using this password the xml files are encrypted/decrypted. Many programs such as firefox, thunderbird, bitcoin, and others support this. I believe thi... 9 Windows Desktop, Linux, Software Architecture, Cryptography, C++ Programming May 25, 2016 Today6d 12h $238
