Openssl Generate Private Key Without Password
In this article you’ll find how to generate CSR (Certificate Signing Request) using OpenSSL from the Linux command line, without being prompted for values which go in the certificate’s subject field.
Below you’ll find two examples of creating CSR using OpenSSL.
Jun 28, 2012 If you find yourself needing to change the password on your private key without affecting the data that's already stored in your database, here's how to do it. The OpenSSL documentation is a little dense on this topic, but these step-by-step instructions should work. Jan 31, 2010 How to create a self signed ssl cert with no passphrase for your test server. Generate your key with openssl. O = Internet Widgits Pty Ltd Getting Private key. Jul 21, 2011 To create a new Private Key without a passphrase. # openssl genrsa -out www.example.com.key 4096 To create a new password protected Private Key. OpenSSL is a powerful cryptography toolkit that can be used for encryption of files and messages. If you want to use the same password for both encryption of plaintext and decryption of ciphertext, then you have to use a method that is known as symmetric-key algorithm. Jan 09, 2018 Generate a self signed certificate without passphrase for private key - create-ssl-cert.sh. Generate a self signed certificate without passphrase for private key - create-ssl-cert.sh. Openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 10000 -nodes. Say I have previously created a private/public key combination, and decided at the time to not protect the private key with a password. If I later decide to 'beef up' security and use a password-protected private key instead, would I need to generate a new private/public key pair, or can I simply add a password to my existing private key?
In the first example, i’ll show how to create both CSR and the new private key in one command.
And in the second example, you’ll find how to generate CSR from the existing key (if you already have the private key and want to keep it).

Both examples show how to create CSR using OpenSSL non-interactively (without being prompted for subject), so you can use them in any shell scripts.
Create CSR and Key Without Prompt using OpenSSL
Use the following command to create a new private key 2048 bits in size example.key
and generate CSR example.csr
from it:
Option | Description |
---|---|
openssl req | certificate request generating utility |
-nodes | if a private key is created it will not be encrypted |
-newkey | creates a new certificate request and a new private key |
rsa:2048 | generates an RSA key 2048 bits in size |
-keyout | the filename to write the newly created private key to |
-out | specifies the output filename |
-subj | sets certificate subject |
Generate CSR From the Existing Key using OpenSSL
Use the following command to generate CSR example.csr
from the private key example.key
:
Option | Description |
---|---|
openssl req | certificate request generating utility |
-new | generates a new certificate request |
-key | specifies the file to read the private key from |
-out | specifies the output filename |
-subj | sets certificate subject |
Automated Non-Interactive CSR Generation
Openssl Verify Key Password
The magic of CSR generation without being prompted for values which go in the certificate’s subject field, is in the -subj
option.
-subj arg | Replaces subject field of input request with specified data and outputs modified request. The arg must be formatted as /type0=value0/type1=value1/type2=…, characters may be escaped by (backslash), no spaces are skipped. |
The fields, required in CSR are listed below:
Field | Meaning | Example |
---|---|---|
/C= | Country | GB |
/ST= | State | London |
/L= | Location | London |
/O= | Organization | Global Security |
/OU= | Organizational Unit | IT Department |
/CN= | Common Name | example.com |
You’ve created encoded file with certificate signing request.
