Password3
Password3 is a blockchain-based dapp. Users generate encryption keys by setting encrypted passwords/questions, which are used on the client side to encrypt sensitive data and permanently stored.
About
The problem it solves People could use this to store sensitive data privately and securely. And they can share access to this encrypted data with others, allowing them to view the data as long as they know the password or can answer the questions correctly.
How it's made
Challenges we ran into I was not sure about how to generate secure password, base on what user has input. because user input could be simple. so I came up with the idea of question and answers list. and with a long random salt, client could get a password from these ingredients. I think it's easy for user to memorize and secure for the dapp to encrypt sensitive data.
