== Applies to: ==
{{NoteBox|title=|content=All versions of Cryptshare Server
}}

== Purpose: ==
This is a step-by-step guide with two possible ways to set up public key authentication on a Cryptshare Server

== Solution: ==
=== Using PuTTYgen ===
# download the tool [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html PuTTYgen]
# generate a new key pair  
[[File:14516503.png]][[File:14516504.png]]
# save the generated public and private keys into files  
[[File:14516507.png]]
# copy the content of the public key into the file '''.ssh/authorized_keys''' on the SECURE COPY REMOTE HOST  
[[File:14516508.png]]
# export the private key  
[[File:14516509.png]]
# add the exported private key to the Cryptshare Administrator interface  
[[File:14516513.png]]
=== Using openSSH ===
# log in on your Linux client
# generate a new key pair using the command '''ssh-keygen'''
 support@cryptshare:~> ssh-keygen 
 Generating public/private rsa key pair.
 Enter file in which to save the key (/home/support/.ssh/id_rsa): 
 Created directory '/home/support/.ssh'.
 Enter passphrase (empty for no passphrase): 
 Enter same passphrase again: 
 Your identification has been saved in /home/support/.ssh/id_rsa.
 Your public key has been saved in /home/support/.ssh/id_rsa.pub.
 The key fingerprint is:
 SHA256:Iz98CDNWeL47PUJg7Q+wD70wHLZKT0Lir4JoG5w3CDQ support@cryptshare
 The key's randomart image is:
