Downloading products using SFTP
 For direct acquisition using SFTP, account authentication or user authentication by public key cryptography is performed.
 When performing user authentication by public key cryptosystem, it is necessary to create secret key / public key beforehand and register its public key in G - Portal. Please refer to "Create your private key ・ Public key yourself", "Register public key" or "Download secret key created with G-Portal" for creating and registering private key ・ public key.
 For the directories that can be accessed, please refer to "Products that can be downloaded via FTP or SFTP" "Directory configuration", for downloading methods using SFTP, please refer to "How to download using SFTP".
 Depending on the organization to which the user belongs, access to the outside by SFTP may be prohibited by policy. In that case, please consult with your network administrator of your organization. G-Portal uses 2051 instead of normal 22 for the TCP port used for SFTP in consideration of safety.
Create your private key ・ public key yourself
This procedure is unnecessary when "Download secret key created with G-Portal" is executed.
(1) UNIX (including Mac OS X)
(1) Open the terminal and execute the following command. (If it can not be executed, check whether ssh is installed.)
$ ssh-keygen


(2) The following message for requesting the save directory and save name of the public key / secret key is displayed.
Enter file in which to save the key (/Users/[UserName]/.ssh/id_rsa):

To specify the save directory and save name, enter the directory name and save name.
If you press enter without entering anything, id_rsa (private key) and id_rsa.pub (public key) will be stored in the default directory / Users / username /.ssh.

(3) The following message will be returned requesting the passphrase for decrypting the private key.
Enter passphrase (empty for no passphrase):

To set the password to be entered when connecting SFTP, enter the password.

This completes the creation of the public key / secret key in the set directory.

(2) Windows
The following outline is an example using the “PuTTY-gen” software application to generate public and private keys. Download PuTTY-gen from the following site and install it on your computer. PuTTY-gen download site: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

(1) Activate PuTTYgen from "All Programs" - "PutTTY Opaque Version" - "PuTTYgen".
(2) Press [Generate] (1), and start to create secret key and public key.
(3) Move the cursor in the blank area of the screen (2). Create a random number and create a key.
(4) (Optional) Enter the password to decrypt the private key. (3)
(5) Click [Save Public Key (U)] and save the public key to your computer. (4)
(6) Press [Save private key] and save the secret key to your computer. (5) Register this public key in G - Portal in the next section. Be sure to create the public key and secret key at the same time.
(7) Press [File] → [Close] and exit PuTTYgen.
Register public key
 In order to do a direct acquisition using SFTP, register the created public key in G - Portal. (Please do not register secret key.The secret key is used to access SFTP server.)

(1) After logging in to the system, click "Account service" on the menu to display the user account service screen.
(2) Specify the public key file from the "Browse" button.
If the public key has already been registered, it will be updated to the specified public key.
(3) With the "Upload" button, the specified public key is registered in this system.
Download secret key created by G-Portal
You can acquire the secret key created by G - Portal.
"Create your own secret key ・ Public key yourself" This procedure is unnecessary when "3.3.2 Register public key" is carried out.

(1) After logging in to the system, click "Account service" on the menu to display the user account service screen.
(2) Click the "Download" button to generate the secret key and download the secret key to your computer. Also, generate a corresponding public key and register it on the GPortal.
