pub struct SignedEnvelope { /* private fields */ }
Expand description

A signed envelope contains an arbitrary byte string payload, a signature of the payload, and the public key that can be used to verify the signature.

For more details see libp2p RFC0002: https://github.com/libp2p/specs/blob/master/RFC/0002-signed-envelopes.md

Implementations§

source§

impl SignedEnvelope

source

pub fn new( key: &Keypair, domain_separation: String, payload_type: Vec<u8>, payload: Vec<u8> ) -> Result<Self, SigningError>

Constructs a new SignedEnvelope.

source

pub fn verify(&self, domain_separation: String) -> bool

Verify this SignedEnvelope against the provided domain-separation string.

source

pub fn payload_and_signing_key( &self, domain_separation: String, expected_payload_type: &[u8] ) -> Result<(&[u8], &PublicKey), ReadPayloadError>

Extract the payload and signing key of this SignedEnvelope.

You must provide the correct domain-separation string and expected payload type in order to get the payload. This guards against accidental mis-use of the payload where the signature was created for a different purpose or payload type.

It is the caller’s responsibility to check that the signing key is what is expected. For example, checking that the signing key is from a certain peer.

source

pub fn into_protobuf_encoding(self) -> Vec<u8>

Encode this SignedEnvelope using the protobuf encoding specified in the RFC.

source

pub fn from_protobuf_encoding(bytes: &[u8]) -> Result<Self, DecodingError>

Decode a SignedEnvelope using the protobuf encoding specified in the RFC.
