Struct BlindedPublicKey

pub struct BlindedPublicKey<K: KeyPair> {
    pub inner: K::PublicKey,
    pub blinding_factor: K::PublicKey,
}

An ECDH public key that has been blinded, enabling a third party to send a message without knowing the cryptographic identity of the recipient.

Fields

inner: K::PublicKey

The blinded public key that can be used to perform a normal Diffie-Hellman key agreement.

blinding_factor: K::PublicKey

Blinding factor used to create the blinded public key.

Carrying this piece of information is necessary because we want a third party to be able to share a secret of its choosing with the party controlling the secret key of the blinded public key.
