IDEA cryptoalgorithm was disabled due to so-called software patent issues. Fortunately all known software patents covering IDEA expired in 2015. It was reenabled in OpenSSL long time ago: https://pkgs.fedoraproject.org/cgit/rpms/openssl.git/commit/hobble-openssl?id=ad05b50
Sorry - expired in 2012.
This needs perl-Crypt-IDEA moving from RPM Fusion into Fedora first. I'd be happy for someone else to take that package.
Confirmed. It's fine for IDEA implementations to return to Fedora. Lifting FE-Legal.
Fixed in perl-Net-SSH-Perl-1.42-6.fc26
