I use everyday the SSH in my laptop to access my Unix account. The client authentication

is password$-$based. Assume that I used the SSH in my laptop to connect my Unix account

two times yesterday and sent the Unix command $$ls $-$a$$ from my laptop to the Unix server

two times in the two separated SSH connections. Was the command $$ls $-$a$$ encrypted

using the same set of security parameters by the SSH in my laptop?
