Implementations

impl DsseEnvelope

pub fn new(payload: &AttestationPayload) -> Result<Self, ShieldError>

Create an unsigned envelope from an attestation payload.

pub fn sign(&mut self, private_key_bytes: &[u8]) -> Result<(), ShieldError>

Sign the envelope with a 32-byte Ed25519 private key.

Appends a new signature entry; can be called multiple times for multi-party signing.

pub fn verify(&self) -> Result<bool, ShieldError>

Verify all signatures in the envelope.

Returns Ok(false) if the envelope is unsigned. Returns Err if any signature is invalid.

pub fn decode_payload(&self) -> Result<AttestationPayload, ShieldError>

Decode and deserialize the payload from the envelope.
