Most modern crypto is all but banned by Fedora's (really Redhat's) packaging policies. They only recently agreed to enable ECDSA in OpenSSL, and even then, only with NIST curves. There's a lot of other very shady overrides and limitations they impose on crytpo packages too, and any questions about them are invariably met with a chorus of "we are not at liberty to comment" from some lawyer type. NSA clearly have them by the balls.
