Crate fxfs_crypto

Modules

• ff1

Structs

• StreamCipher
  A thin wrapper around a ChaCha20 stream cipher. This will use a zero nonce. NOTE: Great care must be taken not to encrypt different plaintext with the same key and offset (even across multiple boots), so consider if this suits your purpose before using it.
• UnwrappedKey
• WrappedKeyBytesV32
• WrappedKeyV32
• WrappedKeysV32
• XtsCipherSet

Enums

• KeyPurpose
  Different keys are used for metadata and data in order to make certain operations requiring a metadata key rotation (e.g. secure erase) more efficient.

Constants

• KEY_SIZE
• WRAPPED_KEY_SIZE

Traits

• Crypt
  An interface trait with the ability to wrap and unwrap encryption keys.

Type Aliases

• KeyBytes
• UnwrappedKeys
• WrappedKey
• WrappedKeyBytes
• WrappedKeys
  To support key rolling and clones, a file can have more than one key. Each key has an ID that unique to the file.
