The SSH keys themselves are private keys; the private key is further encrypted using a symmetric encryption key derived from a passphrase. The key derivation is done using a hash function. Passphrases are commonly used for keys belonging to interactive users. Their use is strongly recommended to reduce risk of keys accidentally leaking from, e. Overview Public key authentication is a way of logging into an SSH/SFTP account using a cryptographic key rather than a password. If you use very strong SSH/SFTP passwords, your accounts are already safe from brute force attacks.

Beyond Compare 3 or 4 Pro allow you to authenticate an SFTP connection using a private key file instead of a password.

Generate Private Key on Linux Server

1. ssh-keygen -m PEM -t rsa
2. Enter to save key as ~/.ssh/id_rsa
3. Enter a passphrase if desired.
4. chmod 700 ~/.ssh
5. cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
6. chmod 600 ~/.ssh/authorized_keys

See the article Redhat Enterprise Linux 6 Deployment Guide - Generating Key Pairs for a more detailed guide to generating private keys.

Several tools exist to generate SSH public/private key pairs. The following sections show how to generate an SSH key pair on UNIX, UNIX-like and Windows platforms.

Generating an SSH Key Pair on UNIX and UNIX-Like Platforms Using the ssh-keygen Utility

UNIX and UNIX-like platforms (including Solaris and Linux) include the ssh-keygen utility to generate SSH key pairs.

Generate Private Key Fiel And Passphrase For Sftp Download

1. Navigate to your home directory:
2. Run the ssh-keygen utility, providing as filename your choice of file name for the private key:

   The ssh-keygen utility prompts you for a passphrase for the private key.

3. Enter a passphrase for the private key, or press Enter to create a private key without a passphrase:

   Note:

   While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

   The ssh-keygen utility prompts you to enter the passphrase again.

4. Enter the passphrase again, or press Enter again to continue creating a private key without a passphrase:
5. The ssh-keygen utility displays a message indicating that the private key has been saved as filename and the public key has been saved as filename.pub. It also displays information about the key fingerprint and randomart image.

Generating an SSH Key Pair on Windows Using the PuTTYgen Program

The PuTTYgen program is part of PuTTY, an open source networking client for the Windows platform.

Generate Private Key Fiel And Passphrase For Sftp Server

1. Download and install PuTTY or PuTTYgen.

   To download PuTTY or PuTTYgen, go to http://www.putty.org/ and click the You can download PuTTY here link.

2. Run the PuTTYgen program.
3. Set the Type of key to generate option to SSH-2 RSA.
4. In the Number of bits in a generated key box, enter 2048.
5. Click Generate to generate a public/private key pair.

   As the key is being generated, move the mouse around the blank area as directed.

6. (Optional) Enter a passphrase for the private key in the Key passphrase box and reenter it in the Confirm passphrase box.

   Note:

   While a passphrase is not required, you should specify one as a security measure to protect the private key from unauthorized use. When you specify a passphrase, a user must enter the passphrase every time the private key is used.

7. Click Save private key to save the private key to a file. To adhere to file-naming conventions, you should give the private key file an extension of .ppk (PuTTY private key).

   Note:

   The .ppk file extension indicates that the private key is in PuTTY's proprietary format. You must use a key of this format when using PuTTY as your SSH client. It cannot be used with other SSH client tools. Refer to the PuTTY documentation to convert a private key in this format to a different format.
8. Select all of the characters in the Public key for pasting into OpenSSH authorized_keys file box.

   Make sure you select all the characters, not just the ones you can see in the narrow window. If a scroll bar is next to the characters, you aren't seeing all the characters.

   How to Generate a Self-Signed Certificate and Private Key using OpenSSL Generating a private key and self-signed certificate can be accomplished in a few simple steps using OpenSSL. We provide here detailed instructions on how to create a private key and self-signed certificate valid for 365 days. How to generate private key and CSR from command line This article describes how to generate a private key and CSR (Certificate Signing Request) from the command line. You may need to do this if you want to obtain an SSL certificate for a system that does not include cPanel access, such as a dedicated server or unmanaged VPS. Jul 09, 2019  Public Key Infrastructure (PKI) security is about using two unique keys: the Public Key is encrypted within your SSL Certificate, while the Private Key is generated on your server and kept secret. All the information sent from a browser to a website server is encrypted with the Public Key, and gets decrypted on the server side with the Private Key. Public key vs private key Public key is embedded in the SSL certificate and private key is stored on the server and kept secret. When a site visitor fills out a form with personal information and submits it to the server, the information gets encrypted with the public key to protect if from eavesdropping.

9. Right-click somewhere in the selected text and select Copy from the menu.
10. Open a text editor and paste the characters, just as you copied them. Start at the first character in the text editor, and do not insert any line breaks.
11. Save the text file in the same folder where you saved the private key, using the .pub extension to indicate that the file contains a public key.
12. If you or others are going to use an SSH client that requires the OpenSSH format for private keys (such as the ssh utility on Linux), export the private key:
    1. On the Conversions menu, choose Export OpenSSH key.
    2. Save the private key in OpenSSH format in the same folder where you saved the private key in .ppk format, using an extension such as .openssh to indicate the file's content.
