# Lit Protocol & Storacha Demo
This demo showcases how to use the Lit network to encrypt data and enable decryption through a Lit Action, which performs custom authentication checks using the ucanto library.
### Setup
Before you start, run `pnpm install` to install dependencies.
### Steps to Run
1. **Build the Lit Action**:
```bash
pnpm run build-actions
```
2. **Obtain the `ipfsHash`**:
Run the following command to get the IPFS CID v0:
```bash
pnpm run ipfsCID
```
Ensure that the hash matches the one in `src/acc.js`. If not, update it.
3. **Upload to IPFS**:
If you modified the Lit Action code, upload the generated files from `src/lit-actions/dist/` to IPFS (CID v0).
4. **Encrypt the File**:
Run the encryption script, passing the file path:
```bash
node src/encrypt.js testFile.md
```
This will output `testFile-encrypted.md` and `dataToEncryptHash.json`, both required for decryption.
5. **Decrypt the File**:
With both output files from the encryption step, run the decryption script:
```bash
node src/decrypt.js
```

### More about Lit Protocol
Lit is a decentralized network where each node operates as a sealed machine, providing a Trusted Execution Environment (TEE). Nodes use Distributed Key Generation (DKG) to collaboratively generate public/private key pairs without any single party holding the entire key. Each node retains a key share for signing and decryption.
Key features relevant to this demo:
- Decentralized key management
- Client-side encryption
- Access control
- Lit Actions for custom workflows
---
### Lit & Storacha Integration
- Lit Protocol enables private data storage on Storacha.
- Files encrypted with Lit can be stored on the Storacha network
- The decryption and access control are managed by Lit.
- Lit Actions can utilize [ucanto](https://github.com/storacha/ucanto) to provide custom decryption capabilities.
