SignRSASha256

Given a piece of data and a private key, calculates an SHA-256 with RSA (SHA256withRSA) signature for the data. Encoded as a base64 string. This signature can then be verified as authentic by a receiver with access to an associated public key.

Note that the implementation supports both PKCS1 and PKCS8 RSA format private keys.

Method Parameters

Parameter	Description
privateKey	The private key used to generate the signature
dataString	The data string to calculate the signature for
