Struct SignedMessage 

#[non_exhaustive]
pub struct SignedMessage;

Ed25519-signed gossip envelope that prevents identity spoofing.

Wire format: [verifying_key: 32 bytes][signature: 64 bytes][content: N bytes]

Since iroh’s PublicKey (NodeId) is an Ed25519 VerifyingKey, a valid signature cryptographically proves the message originated from the claimed NodeId.

Implementations

impl SignedMessage

pub fn sign(secret_key: &SigningKey, content: &[u8]) -> Vec<u8>

Sign content with the node’s Ed25519 secret key.

Returns the serialized wire format: [verifying_key: 32B][signature: 64B][content].

pub fn verify(wire_bytes: &[u8]) -> Result<(VerifyingKey, Vec<u8>)>

Verify a wire-format signed message and extract the original content.

Returns (verifying_key, content_bytes) on success.

Errors

Returns an error if the message is shorter than 96 bytes, the signature is invalid, or the key bytes do not represent a valid Ed25519 public key.

pub fn verify_with_expected( wire_bytes: &[u8], expected_node_id: &PublicKey, ) -> Result<Vec<u8>>

Verify a wire-format message and check that the embedded NodeId matches the signing key. This is a convenience wrapper around [verify].

Errors

Returns an error if verification fails or the NodeId does not match.

pub const fn header_len() -> usize

The length of the signing header in bytes.
