The Raw format for an RSA public key, in this implementation, is a byte sequence consisting of the following:
n (the modulus) in internet order,BigInteger obtained
by invoking the toByteArray() method on the RSA parameter
n,e (the public exponent) in internet order,BigInteger obtained
by invoking the toByteArray() method on the RSA parameter

The Raw format for an RSA private key, in this implementation, is a byte sequence consisting of the following:
p (the first prime factor of the modulus) in internet
order,BigInteger obtained
by invoking the toByteArray() method on the RSA parameter
