# PrivateStamp (Alpha version)
### A private proof-of-existence DApp.
### Prove that you've had a file (of any type & size) at a certain time without compromising your privacy.
`Currently deployed on Rinkeby network`
## Technologies used:
_Solidity_, _Truffle_, _IPFS_, _Javascript_, _Web Crypto API_, _Vue_, _Vuetify_
## You need MetaMask extension installed to interact with the app
## Demo:

## Features:
### Secure:
- Your original file is never transmitted over the network, both encryption & decryption happen locally.
- Every encryption process generate a different file/hash even if the same file is encrypted with the same password, that's because a random salt is generated everytime.
### Decentralized:
- Relies on Ethereum blockchain to store/retrieve data
### Cheap:
`Currently, the app is deployed on test network, so using it is FREE anyway.`
- All expensive operations, such as encryption/decryption/hashing are done locally, only the string that represent the hash that is stored on ethereum.
## Development:
Requirements:
- NodeJS v10 (with node-gyp installed globally)
- `npm` or `yarn`
- `truffle`
Smart contract interaction:
- `truffle migrate`
Frontend app interaction:
- `cd app`
- `npm install` or `yarn`
- `npm run serve` or `yarn serve`
