 This algorithm uses the RSASSA-PKCS1-v1_5 that uses SHA2 hash algorithms. The base for this algorithm is the RSA public key standard. So, to use this algorithm we need a pair of RSA keys. There are many ways to generate these keys in different environments and is outside the scope of this library. Here is one of these ways just for an example:
