good day dear friends, 
in former times i often used the putty-tool (s) for managing the ssh-keys and besides this - to encrypt and decrpyt messages that i exchange with friends
can i run all the putty things on linux too - i guess so:;
see the putty - things - as they work on the general - win architecture
You might have more than one SSH key for a single cloud server, or simply more than one cloud server or Droplet that requires SSH keys to log into. This can make you feel overwhelmed with having to manage, sort out, and link all those keys to their respective servers. That?s why Pageant exists.
Pageant is a PuTTY authentication agent. It holds your private keys in memory so that you can use them whenever you are connecting to a server. It eliminates the need to:
Explicitly specify the relevant key to each Linux user account, if you use more than one account to log into a server
Type a key?s passphrase each time you log into your user account; and your keys should be passphrase protected since having an unprotected key is as good as hiding your password under your keyboard!
well again - i want to run the putty-things on my linux-notebook - can i do this too?
update: - found some interesting articles:

Well - guess that - if i use seahorse - then i have a nice GUI-Tool for linux.

install it (Seahorse ) on my Eos-Installation with
yay bla bla bla
Look forward to hear from you
