Struct MemberKeys 

pub struct MemberKeys { /* private fields */ }

A member’s Ed25519 signing pair and independent X25519 sealing pair (Appendix D). Both secrets erase on drop. Clone is needed by in-memory custody to keep its keys while returning an independently owned unlocked pair.

Implementations

impl MemberKeys

pub fn from_seed(seed: u8) -> Self

A pair whose signing and sealing seeds are both seed: public test data, never a person’s keys.

pub fn generate() -> Result<Self, CryptoError>

Make both member key pairs using the operating system’s randomness.

pub fn public_keys(&self) -> MemberPublicKeys

The public pair admin entries bind to a stable member id (§10).

pub fn sign(&self, bytes: &[u8]) -> Signature

Sign bytes with the member’s Ed25519 pair (§12).

pub fn sign_object(&self, path: &str, digest: &ObjectDigest) -> Signature

Sign the digest of every object byte before the signature (Appendix D.3). Feed the prefix, length fields and sealed chunks to crate::ObjectHasher in storage order. The signed message binds its domain, path and digest. Panics if the storage path is empty.

A file’s content hash cannot stand in for an object’s digest.

use coven_crypto::{ContentHasher, MemberKeys};
let member = MemberKeys::generate().unwrap();
member.sign_object("10101010-1010-1010-1010-101010101010/seq/1", &ContentHasher::new().finish());

pub fn sign_prefix(&self, path: &str, prefix: &[u8]) -> Signature

Sign a snapshot’s exact kind, version and routing fields (D9). The prefix domain and path are bound separately from whole-object signing. Panics if the storage path is empty.

pub fn sign_write_header( &self, path: &str, prefix: &[u8], header: &[u8], roots: &[[u8; 32]], ) -> Signature

Sign a write’s cleartext prefix, sealed header chunk and part roots (D9), separately from the whole-object signature. Panics if the storage path is empty.

pub fn to_secret_bytes(&self) -> SecretBytes

Encode both private seeds for custody or the person’s restore code (§13.1).

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

Restore both pairs from custody or the person’s restore code (§13.1).

pub fn open_store_key( &self, path: &str, prefix: &[u8], sealed: &[u8], ) -> Result<StoreKey, CryptoError>

Open a store-key box, authenticating the exact path and opaque clear prefix. Format checks the recipient and opened identity; the caller checks the introduction commitment before accepting the candidate key. Panics if the storage path is empty.

pub fn open_circle_key( &self, path: &str, prefix: &[u8], sealed: &[u8], ) -> Result<CircleKey, CryptoError>

Open a circle-key box, authenticating the exact path and opaque clear prefix. Format checks the recipient and opened identity; the caller checks the introduction commitment before accepting the candidate key. Panics if the storage path is empty.
