You are right. The "fatal error" disappears if I set
gnutls-min-prime-bits to 256. Yet this choice was just a guess based
on the custom declaration of this variable that suggests a value of
512.
I would appreciate if someone more knowledgable could review the
error messages that I have seen such that they become more helpful
for a nonexpert. Also it would be great if the docstring of
gnutls-min-prime-bits was more precise.
- What is the default value used for min-prime-bits if
gnutls-min-prime-bits is nil?
- What are reasonable values for this variable such that a safe
client-server handshake remains possible, if one needs to customize
this variable? (Or the other way round: if a server wants to use a
prime that is too small, it might really be the better solution to
contact its sysadmin. Yet I couldn't tell when a prime falls below
such a threshold.)
Thanks,
Roland
