It’s unclear to us whether or not Zoom servers use a cryptographically safe random quantity generator to create the assembly encryption keys or whether or not the keys could by some means be predictable. We confirmed that every one members in a Zoom assembly have the similar conf.skey worth and that this key does not change when members be a part of or depart. The important thing does, nonetheless, change when all customers depart the assembly for a interval of time; any new participant becoming a member of an empty assembly will trigger the era of a brand new conf.skey worth.
