      If the public key is an encoded object this will return the ASN.1 primitives encoded - if the bitstring can't be decoded this routine throws an IOException.
      Returns:
        the public key as an ASN.1 primitive.
      Throws:
        `java.io.IOException` - - if the bit string doesn't represent a DER encoded object.
