With ArDrive, your private data never leaves your computer without using military grade (and quantum resistant) encryption.
Every file within a Private Drive is symmetrically encrypted using AES-256-GCM. This is done by getting a master “drive key” by using a combination of the user’s Arweave Wallet signature, their drive password, and a unique drive identifier. Each file has its own “file key” derived from the “drive key”. This allows for single files to be shared without exposing access to other files.
Once a file is encrypted and stored on Arweave, it is locked forever and can only be decrypted using the file key. All Arweave File System compatible clients support this encryption and decryption method.
