Struct SigningKey 

pub struct SigningKey(/* private fields */);

A member’s validated Ed25519 public signing key (Appendix D). It is bound to a stable MemberId by admin entries and is never that identity.

Implementations

impl SigningKey

pub fn from_bytes(bytes: [u8; 32]) -> Result<SigningKey, CryptoError>

Validate a public signing key, refusing invalid and weak Ed25519 points.

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

The validated Ed25519 public key’s 32 bytes.

pub fn verify( &self, message: &[u8], signature: &Signature, ) -> Result<(), CryptoError>

Verify a detached signature against this public key (§12).

pub fn verify_object( &self, path: &str, digest: &ObjectDigest, signature: &Signature, ) -> Result<(), CryptoError>

Verify an object’s signature after hashing all bytes before it (Appendix D.3). The domain and path are authenticated along with the SHA-256 digest. Panics if the storage path is empty.

pub fn verify_prefix( &self, path: &str, prefix: &[u8], signature: &Signature, ) -> Result<(), CryptoError>

Verify a snapshot prefix independently of its encrypted data (D9). prefix is exactly kind, version and routing fields, without signatures. Panics if the storage path is empty.

pub fn verify_write_header( &self, path: &str, prefix: &[u8], header: &[u8], roots: &[[u8; 32]], signature: &Signature, ) -> Result<(), CryptoError>

Verify a write’s header signature without its part chunks (D9): the exact cleartext prefix, the complete sealed header chunk and the part roots. Snapshots carry these to authenticate another member’s leaves. Panics if the storage path is empty.

Trait Implementations

impl Clone for SigningKey

fn clone(&self) -> SigningKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SigningKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for SigningKey

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SigningKey

fn cmp(&self, other: &SigningKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SigningKey

fn eq(&self, other: &SigningKey) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SigningKey

fn partial_cmp(&self, other: &SigningKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
