Struct SigilKeypair 

pub struct SigilKeypair { /* private fields */ }

An Ed25519 keypair for signing SIGIL envelopes.

The signing key is kept in memory only. In production, the private key MUST be stored in a secure enclave or OS keychain (SIGIL Spec §11.4).

Implementations

impl SigilKeypair

pub fn generate() -> Self

Generate a new random Ed25519 keypair using the OS random source.

pub fn from_seed(seed: &[u8; 32]) -> Self

Load a keypair from a raw 32-byte seed (private key scalar).

pub fn verifying_key_base64(&self) -> String

Export the public verifying key as base64url (no padding).

This is the value to store in the DID Document and SIGIL Registry.

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

Export the raw verifying key bytes (32 bytes).
