Of course you can add/remove a passphrase at a later time. Add one (assuming it was an rsa key, else use dsa) openssl rsa -aes256 -in your.key -out your.encrypted.key mv your.encrypted.key your.key chmod 600 your.key the -aes256 tells openssl to encrypt the key with AES256.

Openssl Generate Private Key No Passphrase

Generate an RSA private key using default parameters: openssl genpkey -algorithm RSA -out key.pem. Encrypt output private key using 128 bit AES and the passphrase 'hello': openssl genpkey -algorithm RSA -out key.pem -aes-128-cbc -pass pass:hello. Generate a 2048 bit RSA key using 3 as the public exponent. The openssl req command from the answer by @Tom H is correct to create a self-signed certificate in server.cert incl. A password-less RSA private key in server.key. Openssl req -nodes -new -x509 -keyout server.key -out server.cert Here is how it works. Omitting -des3 as in the answer by @MadHatter is not enough in this case to create a private key without passphrase. Oct 25, 2019  Common OpenSSL Commands with Keys and Certificates.

To gain access to various online services,you may need to obtain an SSH key. To find more out aboutOpen SSH, see the Open SSHManual pages. To generate and send such a key, see the sectionsbelow.

Working with SSH keys

Generating a public/private key pair

To generate a key:

1. Enter the command ssh-keygen -t rsa -C your emailaddress.
   
2. Specify the KeyPair location and name. Administrators recommendyou use the default location if you do not yet have another key there,for example:/home/username/.ssh/id_rsa.
   
3. When prompted, type your user-defined passphrase for the key.

Example input and output follows:

Listing the result

You can find your key under the key location in the .ssh directory,as follows:

Adding or replacing a passphrase for anexisting key

Openssl Generate Rsa Key No Passphrase Password

To change your passphrase, you can simply run the ssh-keygen-p command. Specify the location of your current key, and inputany old or new passphrases. There is no need to regenerate keys.

• Github's GeneratingSSH keys
• Github's Workingwith key passphrases

• This module allows one to (re)generate OpenSSL private keys.
• One can generate RSA, DSA, ECC or EdDSA private keys.
• Keys are generated in PEM format.
• Please note that the module regenerates private keys if they don’t match the module’s options. In particular, if you provide another passphrase (or specify none), change the keysize, etc., the private key will be regenerated. If you are concerned that this could overwrite your private key, consider using the backup option.
• The module can use the cryptography Python library, or the pyOpenSSL Python library. By default, it tries to detect which one is available. This can be overridden with the select_crypto_backend option. Please note that the PyOpenSSL backend was deprecated in Ansible 2.9 and will be removed in Ansible 2.13.”

The below requirements are needed on the host that executes this module.

• Either cryptography >= 1.2.3 (older versions might work as well)
• Or pyOpenSSL
