Thanks.
I don't currently know what key-legths and strengths the official NHS=20
encryption solutions boast (or even provide)=20

I use 4096 and so far as possible avoid positive identification in files =
I=20
move - IE someone needs some other knowledge to make it clear which prson=

note refers to.

I don't casually move important stuff, and what I do would usually be=20
accessible in simpler ways such as asking for it or intercepting paper po=
st.

But I really want more than 50 years - I'm 46 and some of my patients are=

=09(obviously >=3D zero is the real minimum,=20
=09  but those affected so far are at least)=20
=09=09=09=09=09=0923
and my oldest patient is 102

Ouch!
