| |
| | * Launch the PuTTY Key Generator:\\ ''Start'' => ''PuTTY'' => ''PuTTYgen'' |
| |
| | * 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 |
| | * Import the key (and type the passphrase, when asked) with: ''Conversions''=>''Import key''\\ {{ :other:putty_21.png?direct&300 |}} |
| | * 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 |}} |
| |
| | * 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&300 |}} |
| | * 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 |
