Struct HsBlindIdKey

Help

pub struct HsBlindIdKey(PublicKey);

Expand description

The “blinded” identity of a v3 onion service. (KP_hs_blind_id)

This key is derived via a one-way transformation from an HsIdKey and the current time period.

It is used for two purposes: first, to compute an index into the HSDir ring, and second, to sign a DescSigningKey.

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

Tuple Fields§

§0: PublicKey

Implementations§

impl HsBlindIdKey

pub fn id(&self) -> HsBlindId

Return a representation of this key as a HsBlindId.

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

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.
