A class representing a RAW-encoded RSA public key.
The encoding consists of the following, in order:
Each integer is represented as follows:
Byte Length offset (bytes) Meaning 0 2 The length in bits of this BigInteger (MSB first); 2 variable The BigInteger's magnitude with no leading zeroes, again MSB first.
