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.
- An RSA key is a private key based on RSA algorithm, used for authentication and an symmetric key exchange during establishment of an SSL/TLS session. The RSA private key in PEM format (the most common format for X.509 certificates, CSRs and cryptographic keys) can be generated from the command line using the openssl genpkey utility.
- $ cat 'NewKeyFile.key' 'certificate.crt' 'ca-cert.ca' PEM.pem And create the new file: $ openssl pkcs12 -export -nodes -CAfile ca-cert.ca -in PEM.pem -out 'NewPKCSWithoutPassphraseFile' Now you have a new PKCS12 key file without passphrase on the private key part.
Generate Openssl Key Without Password Key Openssl Generate Password While Encrypting a File with a Password from the Command Line using OpenSSLis very useful in its own right, the real power of the OpenSSL library is itsability to support the use of public key cryptograph for encrypting orvalidating data in an unattended manner (where the.
Below you’ll find two examples of creating CSR using OpenSSL.
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 |

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.
Now you can decode CSR to verify that it contains the correct information.
Both the JVM and keytool have problems dealing with keystores without a password. If you try to get a listing of the keystore it will think you didn't provide a password and output falsehoods:
It incorrectly lists our key as being a secret key, which it isn't. We are able to get the correct output by providing the (empty) password in commandline:
Still we have problems when we want to use the keystore in our application. So we'll change it so it has a password. This has to be done in 2 steps. 1. We export the key and certificate to a .pem file. Import password is empty, just press enter here. But be sure to specify a PEM pass phrase. If you leave that empty, it will not export the private key.
We can use keytool to check the new keystore. Use the new password here.
