Function generateSignature

generateSignature(
valueToHash: string | number | boolean | object,
privateKey: string,
): { signature: string; stringifiedValue: string }
Generates a signature using RSA SHA256
Parameters
- valueToHash: string | number | boolean | object
  The value that should be signed. Strings are taken as they are - other types are stringified in a consistent way.
- privateKey: string
  The RSA private key to use for signing the value
Returns { signature: string; stringifiedValue: string }
The generated signature and the (stringified) value that should be used to send along with the signature
