) bits. We would endorse always applying it with 521 bits, For the reason that keys remain smaller and probably more secure compared to the smaller keys (even though they ought to be safe also). Most SSH consumers now support this algorithm.
The private vital is retained with the shopper and will be saved Definitely secret.
