CryptoVault IPFS
A decentralized backup and recovery system that stores encrypted files on IPFS.
Overview
A backup and recovery system that encrypts files with AES-256-CBC and signs their metadata with RSA before storing them on IPFS through Helia. Recovery runs in two steps and keeps the file private to whoever holds the key.
Key Achievements
Encrypted files with AES-256-CBC before they left the client
Signed metadata with RSA so tampering shows up on retrieval
Built a two-step recovery flow for getting a file back
Stored everything on IPFS through Helia, with the keys staying with the user
