Description Nikos Mavrogiannopoulos 2016-05-13 11:09:47 EDT

RHEL includes several cryptographic components who's security doesn't remain constant over time. Algorithms such as (cryptographic) hashing and encryption typically have a lifetime after which they are considered either too risky to use or plain insecure. That would mean we need to phase out such algorithms from the default settings, or completely disable if they could cause irreparable issue. 

This bug is about disabling by default and removing the ability to negotiate the marked as EXPORT ciphersuites. It should not be possible by applications to inadvertently enable them.
