Minimal Anti Collusion Infrastructure (MACI) v2.4.0 / sign

Function: sign()

sign(privateKey, message): Signature<bigint>

Signs a message using the provided private key, employing Poseidon hashing and EdDSA with the Baby Jubjub elliptic curve.

The private key must be an instance of Buffer, Uint8Array or a string. The input will be used to generate entropy and there is no limit in size. The string is used as a set of raw bytes (in UTF-8) and is typically used to pass passwords or secret messages. If you want to pass a bigint, a number or a hexadecimal, be sure to convert them to one of the supported types first. The 'conversions' module in @zk-kit/utils provides a set of functions that may be useful in case you need to convert types.

Parameters​

• privateKey: string | Uint8Array | Buffer

The private key used to sign the message.

• message: BigNumberish

The message to be signed.

Returns​

Signature<bigint>

The signature object, containing properties relevant to EdDSA signatures, such as 'R8' and 'S' values.
