Re-enable the DHE (Ephemeral Diffie-Hellman) cipher suites, which IceCat
|
||
|
|
38.6.0 disabled by default to avoid the Logjam attack. This issue was
|
||
|
|
fixed in NSS version 3.19.1 by limiting the lower strength of supported
|
||
|
|
DHE keys to use 1023 bit primes, so we can enable these cipher suites
|
||
|
|
safely. The DHE cipher suites are needed to allow IceCat to connect to
|
||
|
|
many sites, including https://gnupg.org/.
