Subject: AW: megatools and reg control over key?

Hello again,

Thanks a lot for explaining the process how I could change
the master key and how it is derived. I am very happy that
you created megatools. Since Firefox has "limitations" when
downloading files larger than several GB.

Have a great day.

The keys are not in the browser under the control of JS code provided by, so they can't be simply sent to by their code.

The master key is normally derived from the password, so you'd need to
change your password to change the master key. Megatools doesn't have
a command to do that.
