    privateKey: PrivKey | PrivKey[],
    logger?: Logger,
    message?: string,
): Proof[]
Signs proofs with provided private key(s) if required.
Parameters
- proofs: Proof[]
  An array of proofs to sign.
- privateKey: PrivKey | PrivKey[]
  A single private key or array of private keys (hex string or Uint8Array).
- logger: Logger = NULL_LOGGER
  Optional logger (default: NULL_LOGGER)
- Optionalmessage: string
  Optional. The message to sign (for SIG_ALL)
Returns Proof[]
Signed proofs.
