Add rc.conf variables to control host key length

2012-06-24 Thread Robert Simmons
Here is a set of patches that add functionality to rc.conf allowing users an easy way to control the length of the host keys used with ssh (specifically RSA and ECDSA used with protocol version 2). I would like to also discuss the merits of changing FreeBSD's default behavior to using 4096 bit RSA

In light of advanced in processors and GPUs, what is the potential for duplication of RSA, DSA, and ECDSA keys at the current default key lengths (2048, 1024, and 256 respectively)? ___ freebsd-security@freebsd.org mailing list http://lists.freebsd.org/ma
