Minimal Anti Collusion Infrastructure (MACI) v2.5.0 / PubKey

Class: PubKey

Notice​

A class representing a public key This is a MACI public key, which is not to be confused with an Ethereum public key. A serialized MACI public key is prefixed by 'macipk.' A raw MACI public key can be thought as a pair of BigIntegers (x, y) representing a point on the baby jubjub curve

Constructors​

new PubKey()​

new PubKey(rawPubKey, allowInvalid): PubKey

Create a new instance of a public key

Parameters​

• rawPubKey: PubKey

the raw public key

• allowInvalid: boolean = false

whether to allow invalid public keys

Returns​

PubKey

Dev​

You might want to allow an invalid raw key, as when decrypting invalid messages, the public key data will be random, and likely not be a point on the curve. However we need to match keys to the circuit which does not perform such checks

publicKey.ts:30
