Function scrambledb::data_transformations::convert_blinded_datum

pub fn convert_blinded_datum(
    coprf_context: &CoPRFEvaluatorContext,
    bpk: &BlindingPublicKey,
    ek: &StoreEncryptionKey,
    conversion_target: &[u8],
    datum: &BlindedPseudonymizedData,
    randomness: &mut Randomness
) -> Result<BlindedPseudonymizedData, Error>

Obliviously convert a blinded pseudonymous datum to a given target pseudonym key.

Inputs:

• coprf_context: The Converters CoPRF evaluation context
• bpk: The receiver’s blinding public key
• ek: The receiver’s public encryption key
• conversion_target: Target pseudonym key identifier
• randomness: Random bytes

Output: Blinded pseudonymized datasuch that the datum’s pseudonymous handle is converted to the target pseudonym key and the datum’s value is level-2 encrypted towards the receiver.
