# Lit Password Manager
A web3-native password manager that utilizes decentralized infrastructure and lit protocol to store and retrieve passwords.
Lit Protocol is a decentralized key management network powered by threshold cryptography. A blockchain-agnostic middleware layer, Lit can be used to read and write data between blockchains and off-chain platforms, facilitating encryption, access control, and automation for the open web via programmatic signing.
#### Tech Stack
- Frontend: Next.js, Antd
- Web3 Client: ethers.js
- Smartcontracts: Solidity, Hardhat
- Storage: IPFS, Pinata
- Encryption: Lit Protocol
- Blockchain Network: Polygon Mumbai
- Indexer: The Graph
#### Workflow Architecture:
##### Access Control conditions:
> Its quite surprising that many people use NFT or eth balance based access control. If I posses specific NFT or balance in my account, I should be able to decrypt other users passwords? No. So, I'm using the logic where the user who encrypted the password can only decrypt it. This is a very basis of encryption and decryption of passwords. I'm not sure if this is the right way to do it. I'm open to suggestions.
```javascript
// only the user who encrypted the data should be able to decrypt it
const accessControlConditions = [
{
contractAddress: "",
standardContractType: "",
chain: "mumbai",
method: "",
parameters: [":userAddress"],
returnValueTest: {
comparator: "=",
value: account // ,<=== user address should be dynamic and match the user address connected to the wallet
}
}
];
```
### Prerequisites
> There are some optional prerequisites that you can skip and use my deployed resources instead.
1. [Node.js](https://nodejs.org/en/download/) Nodejs version 14.17.0 or higher.
2. Private key of an Ethereum account with some ETH/Matic in it. (Optional)
3. RPC endpoint of an Ethereum node of your choice. (Optional)
4. [Metamask](https://metamask.io/) extension installed in your browser.
5. Pinata API keys.
6. The Graph Account. (Optional)
### Deployed Resources:
- [Lit Password Manager App](https://lit-password-manager.vercel.app/)
- [Lit Password Manager Subgraph](https://api.thegraph.com/subgraphs/name/salmandabbakuti/key-manager)
- [Lit Password Manager Smartcontract](https://mumbai.polygonscan.com/address/0xc47cf83080ed29e32ccdf1c9a411c9b614820236#code)
## Getting Started
> Copy the `.env.example` file to `.env` and fill in the required values.
#### Deploying Contract (Optional)
```
yarn install
yarn hardhat compile
yarn hardhat deploy --network polygonTest
# copy contract address deployed and paste it in client's .env file
```
#### Deploying Subgraph (Optional)
> Note: Update the `subgraph.yaml` file with the contract address deployed in the previous step. Update deploy script with your own subgraph name.
```
cd indexer
yarn install
yarn codegen
yarn deploy
# copy subgraph url and paste it in client's .env file
```
### Running the client
> Copy the `.env.example` file to `.env` and fill in the required values.
```bash
cd client
yarn install
yarn dev
```
### Safety
This is experimental software and is provided on an "as is" and "as available" basis.
Lit Password Manager is a proof of concept and is not ready for production use. It is not audited and has not been tested for security. Use at your own risk.
