Please register your public key according to the instructions in.
You need to register the public key before login. (NOTE: THE PRIVATE KEY FILE MUST BE KEPT SECRET!) Easy-to-understand name such as "rccs.ppk" or "ccfep.ppk" may be a good choice. We, RCCS, recommend passphrase of 10 or more characters contaning 4 types of characters - "lower-case", "upper-case", "number", and "symbol".Īfter setting passphrase, click "Save private key" button to save the key. You can set passphrase for private key here. (If you lost the private key, you need to generate a new key.) You can rebuild public keys via "Load" button or "Conversion" menu if you still have private key. Extract all the contents in this filed into notepad or others, and then save it! (Do not miss ssh-/ecdsa- part in the beginning!) Note: you don't need public key from "Save public key" button we need only OpenSSH format one. The public key shown as a string in this field is what we need. Once the key generation completed, the appearance of the window will change like above. Key generation(2) - Set passphrase, then save the keys You need to move mouse cursor around to proceed the key generation after clicking the button. Once you click the "Generate" button, the key generation will begin.
In case of ECDSA or RSA type, you may find optional item at the position specified by "2". *In case of RSA key, you need to use PuTTY 0.75 or later. NOTE: Ed448 is not yet available at RCCS frontend nodes. Please choose Ed25519 if you have no preference. PuTTYgen can be launched from Windows start menu.Įd25519, ECDSA (256, 384, 521 bits), and RSA 4096 bits * of keys are recommended in RCCS. SSH key generation (PuTTYgen) Launch PuTTYgen If you already have PuTTY but not PuTTYgen, you can install PuTTYgen (puttygen.exe) from the "Alternative binary files" section of the download page. MSI installer version of the latest stable release available in this page maybe the most standard way to install PuTTY. You can download PuTTY at its official site ( ). The aim of this page is to explain how to login to RCSS supercomputer using PuTTY and PuTTYgen.
Last update: Update for new system, fix official site address, confirmed with PuTTY 0.78 Introduction
