• Openssl Generate Private Key Without Password Code

In some circumstances there may be a need to have the certificate private key unencrypted. To remove the private key password follow this procedure: Copy the private key file into your OpenSSL directory (or you can specify the path in the command line). Run this command using OpenSSL. Rivate key is normally encrypted and protected with a passphrase or password before the private key is transmitted or sent. When you receive an encrypted private key, you must decrypt the private key in order to use the private key together with the public server certificate to install and set up a working SSL, or to use the private key to decrypt the SSL traffic in a network protocol. I'm not sure what Azure means by 'without a password'. OpenSSL can create a PKCS12 with the contents unencrypted, but it still has a PBMAC which uses a password - but which a reader that violates the standard can ignore. If that is close enough, if you have the separate key and cert both in PEM. $ 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.

In my case I would like to create certs without the private keys because they are generated on smart cards and they cannot be exported ever. And no, cards do not generate CSR during key generation. I have not found any option in OpenSSL create a certificate from the sole public key. 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.

Solution

In some circumstances there may be a need to have the certificate private key unencrypted.
To remove the private key password follow this procedure:

Openssl Generate Private Key Without Password Code

1. Copy the private key file into your OpenSSL directory (or you can specify the path in the command line).
   
2. Run this command using OpenSSL:

   
   Enter the passphrase and [file2.key] is now the unprotected private key.

   The output file: [file2.key] should be unencrypted. To verify this open the file using a text editor (such as MS Notepad) and view the headers.
   Encrypted headers look like this:
   -----BEGIN RSA PRIVATE KEY-----
   Proc-Type: 4,ENCRYPTED DEK-Info: DES-EDE3-CBC,

   
   6AC307785DD187EF..
   -----END RSA PRIVATE KEY----- Javascript generate dynamic key values in an object.

   
   Unencrypted headers look like this:
   -----BEGIN RSA PRIVATE KEY-----
   6AC307785DD187EF..
   -----END RSA PRIVATE KEY-----

   WARNING: Be aware that having an unencrypted private key adds a security risk by making it easier to obtain your private key if the private key file is stolen.
