Ssh-keygen -lf on the server only gives me the md5 print, and for the life of me I can't find how to get the sha256 one either in the man pages or the www so far. – codeling Nov 12 '15 at 21:09 6 I added a snipped from the OpenSSH Cookbook using sha256sum to the answer.
We are a bit more strict about our security than most hosts in that we do not use the traditional username/password combination to access web sites. Instead we use shared SSH keys. These are fairly easy to manage on Mac/Linux machines. You probably already have an SSH key on your Mac. If not it's easy to generate one. Open the Terminal application (in Applications > Utilities) and type this: cat ~/.ssh/id_rsa.pub If you see a bunch of gibberish starting with 'ssh-rsa AAAAB3Nz' you have a key!
Just press the up-arrow on your keyboard (which will show the last command typed) and add the pipe along with 'pbcopy' (pbcopy is a command line utility to copy to the keyboard). Executable for mac. So you will have: cat ~/.ssh/id_rsa.pub pbcopy If you get a message saying 'No such file or directory', no problem! Just type this: ssh-keygen -b2048 Hit return at all of the prompts.
Cad for mac free download. You will see this: The key's randomart image is: +---[RSA 2048]----+ .oooo+o+Oo .=.BO o+ E = XoBo*. X =.X. o + S = . + * +----[SHA256]-----+ Now just run this again: cat ~/.ssh/id_rsa.pub pbcopy.and open an email and paste your clipboard and send it to us!
