Struct FileKey 

pub struct FileKey(/* private fields */);

A random 32-byte key for one immutable file, erased on drop. Never reuse this key and a chunk index with different plaintext.

Implementations

impl FileKey

pub fn generate() -> Result<Self, CryptoError>

Generate a file key independently of store and circle keys.

pub fn from_bytes(bytes: [u8; 32]) -> Self

Import the key carried in a row’s where-column.

pub fn to_secret_bytes(&self) -> SecretBytes

Export the key for its where-column; the returned bytes erase on drop.

pub fn seal_chunk( &self, path: &str, header: &[u8], index: u64, plaintext: &[u8], ) -> Vec<u8>

Seal a chunk, binding the path, whole cleartext header and index. The output is ciphertext and tag; its nonce is not stored. Panics if the storage path is empty.

pub fn open_chunk( &self, path: &str, header: &[u8], index: u64, sealed: &[u8], ) -> Result<Vec<u8>, CryptoError>

Open only at the authenticated file path, header and chunk index. Panics if the storage path is empty.

Trait Implementations

impl Debug for FileKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
