[Appologies for the delay.] Then it seems that the articles which favoured gcm presumed that it would only get use with aesni or equivalent, or that I misread the authors' intent. :( An alternative would be an easy way to specify a preferred option for configs Ciphers, KexAlgorithms and/or MACs without disabling the defaults and without having to re-specify all of them. It might take the form of a string, such as DEFAULT, which expands to the default list or something like preferredCiphers, preferredKex and preferredMACs which, if set, are tried first. The ability to prefer a given algorithm set w/o blocking connections to hosts which cannot handle that set is useful. Doing so w/o having to duplicate the full list in the config file is even better. -JimC -- James Cloos <cloos at jhcloos.com> OpenPGP: 1024D/ED7DAEA6 -------------- next part -------------- A non-text attachment was scrubbed...
