Fields

version: String

The version of the dm-verity target.

block_device_path: String

The path to the data block device to be verified.

hash_device_path: String

The path to the block device containing the Merkle tree hashes.

data_block_size: u64

The size of a data block in bytes.

hash_block_size: u64

The size of a hash block in bytes.

num_data_blocks: u64

The total number of data blocks on the data device.

hash_start_block: u64

The root block index on the hash device where the Merkle tree begins.

hash_algorithm: HashAlgorithm

The cryptographic hash algorithm used (e.g., SHA256 or SHA512).

root_digest: String

The hexadecimal encoded root digest of the Merkle tree. This hash should be trusted.

salt: String

The hexadecimal encoded salt used when hashing blocks.

optional_params: DmVerityTargetOptionalParams

Optional target parameters.
