Subject: It suddenly strikes me as probably a good idea to enforce that anyone
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/putty/commitdiff_plain/a924e32dfbacc918d25ce4f82842f41cb61f3506

It suddenly strikes me as probably a good idea to enforce that anyone
calling random_byte has previously called random_ref.

(I'm not aware of any current code getting this wrong! It just seems
to me to be the sort of thing you'd want to be really sure of.)
