How to Create a Public/Private Key Pair
The standard procedure for creating a Secure Shell public/private key pair follows. For information on additional options, see ssh-keygen(1).
- Start the key generation program.
- Enter the path to the file that will hold the key.By default, the file name id_rsa, which represents an RSA v2 key, appears in parentheses. You can select this file by pressing Return. Or, you can type an alternative filename.The public key name is created automatically and the string .pub is appended to the private key name.
- Enter a passphrase for using your key.This passphrase is used for encrypting your private key. A good passphrase is 10–30 characters long, mixes alphabetic and numeric characters, and avoids simple English prose and English names. A null entry means no passphrase is used, but this entry is strongly discouragedfor user accounts. Note that the passphrase is not displayed when you type it in.
- Re-enter the passphrase to confirm it.
- Check the results.The key fingerprint (a colon-separated series of 2 digit hexadecimal values) is displayed. Check that the path to the key is correct. In the example, the path is /home/johndoe/.ssh/id_rsa.pub. At this point, you have created a public/private key pair.
- Copy the public key and append the key to the $HOME/.ssh/authorized_keys file in your home directory on the remote host.

Select (1) DSA and Elgamal (default) to allow the generated key to both encrypt and sign data. This will generate a public-private key pair in the GPG keyring and prompt for the size of the encryption key: ELG-E keys may be between 1024 and 4096 bits long. What keysize do you want? (2048) Select the default value of 2048. Generating a Secure Shell (SSH) Public/Private Key Pair 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. Oct 12, 2016 Angela from the API support team walks through how to generate a public private key pair using OpenSSL and register a private application. If you want to try integrating to Xero, partner. First, it picks a random key and encrypt the full message with that key. This first encryption is simply a regular one-way cipher. Next, the random key we used in the first encryption is itself encrypted using the public or private key. Now, only the matching public/private key can decrypt the one-way key used to encrypt the full message.
