+  * **Do not lose** the (existing) ssh keys files you have, or the keys that you will create
+    * It's a very good idea to **keep a copy of these files** on another computer!
-==== Importing or creating ssh keys with PuTTYgen ====
+  * **Do not forget** the passphrase that will be used to unlock the private key
-  * Launch the PuTTY Key Generator:\\ ''Start'' => ''PuTTY'' => ''PuTTYgen''
+  * If you save the passphrase in a file, **do not** put this file in the same place as the ssh keys
-  * If you already have a private ssh keys generated on another computer, ''id_rsa'', you just have to use PuTTYgen to **import the private key**, and save it to a ''.ppk'' file that ''Pageant'' can use
+  * Easiest thing to do is probably to store the key files in an ''ssh'' sub-directory somewhere
-    * Import the key (and type the passphrase, when asked) with: ''Conversions''=>''Import key''\\ {{ :other:putty_21.png?direct&300 |}}
+    * We assume below that they keys are in a sub-directory of your [[other:win10config#the_most_important_folders|local HOME FOLDER]]\\ \\ <some_disk_different_from_c>:\Users\<your_login>\ssh\
-    * Then click on the ''Save private key'' button, and create a ''id_rsa.ppk'' file (or ''any_name_you_want.ppk'')\\ {{ :other:putty_22.png?direct&300 |}}
+</WRAP>
-  * If you don't have a set of ssh keys, follow the steps below to **create private and public keys**
-    * Make sure that the type of key (at the bottom of the PuTTYgen window) is ''RSA'' and that the number of bits is ''4096''
-    * Click on the ''Generate'' button and move your mouse to generate some random information
-    * Type your ''Key passphrase'' and confirm it

-    * Click on the ''Save public key'' button, and create a ''id_rsa.pub'' file
-    * Click on ''Conversions''=>''Export OpenSSH key'', and create a (standard) ''id_rsa'' file\\ You will not need this file with Putty, but it is just in case you need to use your private key later on a Linux computer

+==== Converting existing ssh keys with PuTTYgen ====
+If you already have a private ssh keys generated on another computer (e.g. an ''id_rsa'' text file), you just have to use ''PuTTYgen'' to **import the existing private key**, and then export it to a //converted// ''.ppk'' file that ''Pageant'' can use

+  * Click on the ''Save public key'' button, and create a ''id_rsa.pub'' file
+    * You will need to [[other:ssh#installing_ssh_keys|install the public key]] on all the remote Linux server that you want to connect to using the ssh agent, instead of typing your password
+  * Click on ''Conversions''=>''Export OpenSSH key'', and create a (standard) ''id_rsa'' file\\ You will not need this file with Putty, but it is just in case you need to use your private key later on a Linux computer
+==== Using the private key in Pageant ====
+We assume that the **private key file** is available locally in ''<some_disk_different_from_c>:\Users\<your_login>\ssh\''
+  * Start ''Pageant'' and open the ''Pageant Key List'' window by:
+    * Double-clicking (left mouse button) on ''Pageant''
+    * Or right-clicking on ''Pageant'' and choosing ''View keys''
+  * Click on ''Add Key'', navigate to the directory where you have stored the ''.ppk'' converted private key file (e.g. ''\Users\<your_login>\ssh\''), open it and type your passphrase. You can ''Close'' the ''Pageant Key List'' once the key appears there\\ {{ :other:putty_private.png?direct&300 |}}
+  * If everything was done correctly, you should now be able to open the //Sessions// defined in ''Pageant'', on remote servers where the **public key matching the private key** used in ''Pageant'' was [[other:ssh#installing_ssh_keys|installed correctly]]
