Function oprf::coprf::coprf_online::blind_evaluate

pub fn blind_evaluate(
    key: CoPRFKey,
    bpk: BlindingPublicKey,
    blind_input: BlindInput,
    randomness: &mut Randomness
) -> Result<BlindOutput, Error>

Blind PRF Evaluation is performed using the homomorphic properties of Elgamal ciphertexts. Further, the converter rerandomizes every ciphertext that it receives in order to achieve resistance against collusion between requester and receiver.
