Struct HsDescSigningKey 

pub struct HsDescSigningKey(PublicKey);

A key used to sign onion service descriptors. (KP_desc_sign)

It is authenticated with a HsBlindIdKey to prove that it belongs to the right onion service, and is used in turn to sign the descriptor that tells clients what they need to know about contacting an onion service.

Onion services create a new DescSigningKey every time the HsBlindIdKey rotates, to prevent descriptors made in one time period from being linkable to those made in another.

Note: we use a separate signing key here, rather than using the HsBlindIdKey directly, so that the HsBlindIdKeypair can be kept offline.

Trait Implementations

impl AsRef<PublicKey> for HsDescSigningKey

fn as_ref(&self) -> &PublicKey

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for HsDescSigningKey

fn clone(&self) -> HsDescSigningKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ConstantTimeEq for HsDescSigningKey

where PublicKey: ConstantTimeEq,

fn ct_eq(&self, other: &Self) -> Choice

Determine if two items are equal.

fn ct_ne(&self, other: &Self) -> Choice

Determine if two items are NOT equal.

impl Debug for HsDescSigningKey

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

Formats the value using the given formatter.

impl Deref for HsDescSigningKey

type Target = PublicKey

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl From<HsDescSigningKey> for PublicKey

fn from(value: HsDescSigningKey) -> Self

Converts to this type from the input type.

impl From<PublicKey> for HsDescSigningKey

fn from(value: PublicKey) -> Self

Converts to this type from the input type.

impl PartialEq for HsDescSigningKey

where HsDescSigningKey: ConstantTimeEq,

fn eq(&self, other: &Self) -> 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.
