The cracklib dicts in Fedora is 8.3M. (I'm sure some of this is my fault, as I've added to it over the years.) The cracklib pam module supports a compressed dictionary, but apparently it has a serious performance impact (https://bugzilla.redhat.com/show_bug.cgi?id=1004896). Meanwhile, in many systems today, local passwords are entirely unused. Authentication is done via keys or by kerberos. At the same time, we have an increased need for smaller systems. That 8MB starts to be a meaningful fraction of a container or an ultra-small cloud image. I do recognize the value of protecting against dictionary-based attacks when passwords are used. Maybe we could have a policy which requires _longer_ passwords but uses a much smaller dictionary? -- Matthew Miller ☁☁☁ Fedora Cloud Architect ☁☁☁ <mattdm@xxxxxxxxxxxxxxxxx> -- security mailing list security@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/security
