Struct UpdateVerifier 

pub struct UpdateVerifier { /* private fields */ }

Verifies software update packages before installation.

Register one or more trusted publisher keys with register_publisher, then call verify for each candidate update. Failed verifications are automatically recorded in a supplied UpdateVerificationLog.

Implementations

impl UpdateVerifier

pub fn new() -> Self

Create a verifier with no trusted publishers.

pub fn register_publisher(&mut self, publisher_id: &str, key: VerifyingKey)

Register a trusted publisher key.

Only updates signed by a registered publisher will pass verification.

pub fn verify( &self, update: &SoftwareUpdate, payload: &[u8], publisher_id: &str, log: &mut UpdateVerificationLog, ) -> Result<(), UpdateVerifyError>

Verify update against payload and record the outcome in log.

Returns Ok(()) only when:

• publisher_id is registered,
• BLAKE3(payload) == update.payload_hash, and
• the Ed25519 signature is valid.

Any failure appends a UpdateVerifyDecision::Rejected entry to log and returns the corresponding UpdateVerifyError.
