Expand description

Verifiable encryption

Use this statement when you know all the possible encrypted values and you want to prove that a specific value is one of them. To decrypt, you need to know the secret key and try all possible values until you find the one that matches the ciphertext.

Fields§

§message_generator: P

The generator for the message element

§encryption_key: PublicKey<Bls12381G2Impl>

The encryption key for this ciphertext

§id: String

The statement id

§reference_id: String

The other statement id

§claim: usize

The claim index in the other statement
