Abstract
A general purpose distributed encrypted file system generates a block key on a client machine. The client machine encrypts a file using the block key. Then, the client encrypts the block key on the first client machine with a public key of a keystore associated with a user and associates the encrypted block key with the encrypted data block as crypto metadata. The client machine caches the encrypted data block and the crypto metadata and sends the encrypted data block and the crypto metadata to a network file system server. When the client machine receives a return code from the network file system server indicating successful writes of the encrypted data block and the crypto metadata, the client machine clears the cached encrypted data block and the crypto metadata.
