Re: [arch-general] Any way to decrypt hashes set by ssh HashKnownHosts?

Hi, Was this change forwarded to the OpenSSH developers? I am sure that if it is indeed better security-wise to hash the known_hosts file, they would change the default configuration upstream. I'm also sure that they would give very good reasons for not wanting to do so. Thanks, Dimitris

Just on a whim, I decided to try out the Debian tool to scan for weak keys resulting from the recent openssl security hole. And lo and behold, it found 2 weak keys in my known_hosts file! Problem is, though, since Arch recently turned on HashKnownHosts by default in ssh_config, those 2 lines
