Struct Response 

Source 
pub struct Response(/* private fields */);
Expand description

Contains a response upon ticket acknowledgement It is equivalent to a non-zero secret scalar on secp256k1 (EC private key).

Implementations§

Source§

impl Response

Source

pub fn to_challenge(&self) -> Result<Challenge, CryptoError>

Converts this response to the PoR challenge by turning the non-zero scalar represented by this response into a secp256k1 curve point (public key).

Note that this is an expensive operation involving scalar multiplication.

Error is returned when this Response contains an invalid value.

Source

pub fn from_half_keys( first: &HalfKey, second: &HalfKey, ) -> Result<Response, CryptoError>

Derives the response from two half-keys.

This is done by adding together the two non-zero scalars that the given half-keys represent. Returns an error if any of the given scalars is zero.
