+ | |||
+ | 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 | ||

+ | ==== Creating ssh keys with PuTTYgen ==== | ||
+ | |||
+ | 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 private key'' button, and create a ''id_rsa.ppk'' file (or ''any_name_you_want.ppk'')\\ {{ :other:putty_23.png?direct&400 |}} | ||
+ | * 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]] | ||
