> SYNC
< OK
> SET_GENERATOR, [64 bit prime
number]
< OK
Set the encryption key generator
> SET_MODULUS, [64 bit prime
number]
< OK
Set the encryption key modulus
> REQUEST_KEY_EXCHANGE, [64
bit host intermediate key]
< OK, [64bit slave intermediate key]
Host sends the host intermediate
key, the slave responds with the
slave intermediate key. The
encryption key is then calculated
independently by both the host and
the slave.
