Struct Envelope 

pub struct Envelope { /* private fields */ }

Immutable input and canonical image, validated without authorizing a flash.

Implementations

impl Envelope

pub fn load(input: &[u8]) -> Result<Self, Error>

Load exactly one 2 MiB plaintext or OEM encrypted image. Positive boot framing and a nonempty valid CMAC table are required. Raw captures are rejected. No model, filename or absence of encryption selects a format.

pub fn original(&self) -> &[u8]

Original input, retained unchanged for provenance.

pub fn image(&self) -> &[u8]

Canonical stored image, used for acceptance and readback verification.

pub fn input_encoding(&self) -> InputEncoding

Original input encoding; does not select the receiver’s transfer mode.

pub fn chip(&self) -> Chip

Controller generation established by canonical image analysis.

pub fn input_sha256(&self) -> &[u8; 32]

SHA-256 of the original bytes.

pub fn image_sha256(&self) -> &[u8; 32]

SHA-256 of canonical stored bytes.
