A super safe and super slow password manager.
This project is a work in progress.
With this tool, you can store your passwords on the blockchain safely. The passwords are encrypted with a key that only you know.
This project uses a very slow key generation algorithm, which can take several hours per key generation. The key is generated from a password and a private seed you provide.
Because it uses such a slow key generation algorithm, it is inherently resistant to dictionary attack and brute-force cracking attack, and even to some extent to social engineering attack.
You can specify time control parameters h to control the time spent by the key generation algorithm. The time complexity of key generation algorithm is O(2^h) in average.
astral-mask-encrypt generates the key and encrypts the data with threefish algorithm. The encrypted data is stored on the blockchain using astral-mask-storage smart contract.
To protect your passwords. You should use a unique complex unapproachable password. You should also use a unique private seed. Each key is generated from the password and the private seed. If you use the same password and private seed, you will get the same key.
The project contains 3 main parts:
astral-mask-encrypt- a command line tool to encrypt and decrypt string using a key.astral-mask-storage- a smart contract to store encrypted data on the blockchain.astral-mask-dashboard- a web application to manage encrypted data.
