If you need to share a key with someone else, you can export it from your Linux machine using the export command. This will allow you to save the key in a file that can be transferred to the other person. To use the export command, you will need to specify the name of the key that you want to export and the location where you want to save the file.
How to export a key in Linux
1. Export your public key
If you want to export your public key so that others can use it, you can do so using the command line. First, make sure that you are in the same directory as the file that contains your public key. Then, type the following command:
gpg –export your_email@address.com > public_key.txt
This will export your public key to a file called public_key.txt. You can then share this file with others so that they can import your public key.
2. Export your private key
If you want to export your private key so that you can move it to a different computer, you can do so using the command line. First, make sure that you are in the same directory as the file that contains your private key. Then, type the following command:
gpg –export-secret-keys your_email@address.com > private_key.txt
This will export your private key to a file called private_key.txt. You should then move this file to a secure location such as a USB drive or an encrypted disk image.
3. Export both your public and private keys
If you want to export both your public and private keys, you can do so using the command line. First, make sure that you are in the same directory as the file that contains your keys. Then, type the following command:
gpg –export your_email@address.com > keys.txt
This will export both your public and private keys to a file called keys.txt. You should then move this file to a secure location such as a USB drive or an encrypted disk image.
How to export a public key in Linux
Export a public key in Linux using the ssh-keygen command. The ssh-keygen command is used to generate, manage, and convert SSH keys. It is used to generate public/private key pairs for use with SSH.
To export a public key, use the -e option. This will export the public key in the specified format. The default format is PEM, which can be exported to a file using the -o option.
The ssh-keygen command can also be used to manage your SSH keys. To view the contents of your SSH key ring, use the -l option. To delete a key from your SSH key ring, use the -R option.
How to export a private key in Linux
Assuming you have a private key in text format, the following command will print the key in an SSH2-compatible format:
ssh-keygen -e -f private.key
This can be useful if you need to use your key with an older SSH server that doesn’t support the newer RSA key formats.
How to export an RSA key in Linux
Assuming you have an RSA keypair in a file called mykey.pem, exporting the public key is as simple as:
openssl rsa -in mykey.pem -outform PEM -pubout -out mypubkey.pem
Exporting the private key is a little more involved, as you need to first decrypt it (if it is encrypted):
openssl rsa -in mykey.pem -outform DER -out myprivkey.der
If your key is not encrypted, you can omit the -outform and -passout arguments.
How to export a PGP key in Linux
There are a few steps to follow in order to export a PGP key in Linux. Firstly, open up a terminal and use the command ‘gpg –export’. This will give you a list of all the PGP keys that are currently on your system. Find the key that you want to export and then use the command ‘gpg –export-secret-keys’. This will export the private key for the selected key. You will then be asked for a passphrase, which is used to protect your private key. Once you have entered the passphrase, the private key will be exported and saved to a file.
How to export an SSH key in Linux
To export an SSH key in Linux, you will first need to generate a key pair using the ssh-keygen command. Once you have done this, you will need to use the ssh-copy-id command to copy the public key to the remote server. Finally, you will need to use the chmod command to change the permissions of the private key file.

To export an OpenSSL key in Linux, use the following command:
openssl rsa -in
