Struct HsIdKeypair

pub struct HsIdKeypair(ExpandedKeypair);

The private counterpart of a [`HsIdKeyKey’].

This is stored as an expanded secret key, for compatibility with the C tor implementation, and in order to support custom-generated addresses.

(About custom generated addresses: When making a vanity onion address, it is inefficient to search for a compact secret key s and compute SHA512(s)=(a,r) and A=aB until you find an s that produces an A that you like. Instead, most folks use the algorithm of rend-spec-v3.txt appendix C, wherein you search for a good a directly by repeatedly adding 8B to A until you find an A you like. The only major drawback is that once you have found a good a, you can’t get an s for it, since you presumably can’t find SHA512 preimages. And that is why we store the private key in (a,r) form.)

Implementations

impl HsIdKeypair

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

Trait Implementations

impl AsRef<ExpandedKeypair> for HsIdKeypair

fn as_ref(&self) -> &ExpandedKeypair

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

impl Debug for HsIdKeypair

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

Formats the value using the given formatter.

impl From<&HsIdKeypair> for HsIdKey

fn from(value: &HsIdKeypair) -> Self

Converts to this type from the input type.

impl From<ExpandedKeypair> for HsIdKeypair

fn from(value: ExpandedKeypair) -> Self

Converts to this type from the input type.

impl From<HsIdKeypair> for ExpandedKeypair

fn from(value: HsIdKeypair) -> Self

Converts to this type from the input type.

impl From<HsIdKeypair> for HsIdKey

fn from(value: HsIdKeypair) -> Self

Converts to this type from the input type.

impl ToEncodableKey for HsIdKeypair

type Key = ExpandedKeypair

The key type this can be converted to/from.

type KeyPair = HsIdKeypair

fn from_encodable_key(key: Self::Key) -> Self

Convert an EncodableItem to another key type.
