Client-Side Encryption is a security feature that encrypts files on the user's device before they are uploaded to a decentralized file storage network. This ensures that sensitive data remains confidential and is only accessible to users who possess the correct decryption keys. By performing encryption locally, the feature mitigates risks associated with data breaches and unauthorized access during transmission and storage. It empowers users with control over their data privacy and security, making it a critical component for any decentralized storage solution.
