Re: [Safekeep-devel] Support for SSH ed25519 keys, switch default key type to RSA

[Frank C. <fr...@cr...>]

Alexander,

Thanks for that patch.  I did notice that recently and was going to
code something up to fix it, however, you beat me to it.

I'll apply it shortly.

I was also thinking of going further and making it a possible
configuration option, either globally or on a host by host basis.  What
do you think?

Regards
Frank
