SSL_PKEY_INFO Structure

typedef struct {
  WORD pub_size_bytes;
  BYTE pub_key[SSL_RSA_CLIENT_SIZE/8];
  BYTE pub_e[3];
  BYTE pub_guid;
} SSL_PKEY_INFO;

To hash the public key information, we need to actually get the public key information... 1024 bit key at 8 bits/byte = 128 bytes needed for the public key.
