Crate fsverity_merkle 

fsverity_merkle contains types and methods for building and working with fsverity merkle trees.

Structs

FsVerityDescriptor

A descriptor struct for fsverity. It does not own the bytes backing it.

FsVerityDescriptorRaw

The raw structure of an FsVerity descriptor. The values in this are not necessarily valid.

FsVerityHasherOptions

FsVerityHasherOptions contains relevant metadata for the FsVerityHasher. The salt is set according to the FsverityMetadata struct stored in fxfs and block_size is that of the filesystem.

MerkleTree

A MerkleTree contains levels of hashes that can be used to verify the integrity of data.

MerkleTreeBuilder

A MerkleTreeBuilder generates a MerkleTree from one or more write calls.

MerkleVerifier

Verifies data blocks against a pre-validated Merkle tree.

Sha256Hash

SHA-256 verity hash.

Sha512Hash

SHA-512 verity hash.

Enums

FsVerityHasher

FsVerityHasher is used by fsverity to construct merkle trees for verity-enabled files. FsVerityHasher is parameterized by a salt and a block size.

Constants

SHA256_SALT_PADDING

SHA512_SALT_PADDING

Traits

FsVerityHash

A cryptographic hash digest used in a Merkle tree.

Functions

from_slice

Compute a merkle tree from a &[u8] for a particular hasher.
