HsIdKey

tor_hscrypto::pk

Struct HsIdKey

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

Expand description

The identity of a v3 onion service, expanded into a public key. (KP_hs_id)

This is the decoded and validated ed25519 public key that is encoded as a ${base32}.onion address.

This key is not used to sign or validate anything on its own; instead, it is used to derive a HsBlindIdKey.

Note: This is a separate type from HsId because it is about 6x larger. It is an expanded form, used for doing actual cryptography.

Implementations§

impl HsIdKey

pub fn id(&self) -> HsId

Return a representation of this key as an HsId.

(HsId is much smaller, and easier to store.)

impl HsIdKey

pub fn compute_blinded_key( &self, cur_period: TimePeriod, ) -> Result<(HsBlindIdKey, Subcredential), BlindingError>

Derive the blinded key and subcredential for this identity during cur_period.

pub fn compute_subcredential( &self, blinded_key: &HsBlindIdKey, cur_period: TimePeriod, ) -> Subcredential

Given a time period and a blinded public key, compute the subcredential.

Methods from Deref<Target = PublicKey>§

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

Return a reference to the byte representation of this public key.

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

Return the byte representation of this public key.

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

Verify a signature using this public key.

See ed25519_dalek::VerifyingKey::verify for more information.
