    opts?: IRsaOptions,
): Buffer
Hash a message with the specified hash/digest algorithm.
Parameters
- algo:
      | "md5"
      | "ripemd160"
      | "sha1"
      | "sha224"
      | "sha256"
      | "sha3-224"
      | "sha3-256"
      | "sha3-384"
      | "sha3-512"
      | "sha384"
      | "sha512"
  The hash/digest algorithm to use.
- privateKey: string | Buffer<ArrayBufferLike> | KeyObject
  The private key to sign the message with.
- message: string | Buffer<ArrayBufferLike>
  The payload to be signed, can be a Buffer or a string.
- Optionalopts: IRsaOptions
  The options for signing, including the passphrase of the private key and the padding algorithm.
Returns Buffer
Return a Buffer that contains the signature of the payload.

Throws
E_INVALID_PRIVATE_KEY If the private key is not a valid RSA private key.

Throws
E_SIGN_FAILED If the signing fails.
