#8 generate key pairs and fingerprints for IDs

8fac7489df

Using a low prime for performance.

I ran into what I thought was a bug, but it happens because some of node wraps non-javascript.

For the fingerprint, I decided to use a sha1 on the entire pub key for now during development.

Note to self from zPlus:

the man of ssh-keygen says -E, so something like ssh-keygen -E (md5|sha256) -l -f

Not going to do any of this in the frontend anymore.
