Generate PFX file using OPENSSL on Windows

Had a situation where a client needed a PFX with password for a particular setup. This is something I have not done before, so here are the steps

Generate the key and the CSR 

Enter the password when requested. Please ensure you remember this.

Replace domain with your domain name for simplicity.

openssl req -newkey rsa:2048 -nodes -keyout domain.key -out domain.csr

Once validated, you have should have access to these in the package.

• The root cert files
• intermediate cert files
• the domain crt from the  TLS/SSL certificate provider.

Run the command to import the files, root, intermediate and domai. 

Note in some cases you will have 2 or more intermediate files, please combined into one file and call intermeidate.crt. Rename the "root" cert, rootca.crt. 

Generate the PFX

openssl pkcs12 -export -out domain.pfx -in rootca.crt -in intermediate.crt  -in domain.crt -inkey domain.key

You will now have the pfx file for use along with the password.

Possible Fix for BAD_SYSTEM_CONFIG_INFO 75736e6a726e6c2e 500

 Today I woke up to this error on a Dell Precision 3541 Laptop. For some reason it was asking for the Bitlocker Key.

After entering the key, received the following error on boot up

BAD_SYSTEM_CONFIG_INFO

After searching around I was advised to start here 

chkdsk C: /f /r /x

It did showed 1 bad file cluster that was fixed.

However, we  ran into another error. 

"unspecified error 75736e6a726e6c2e 500

Somewhere a user advised to simple run chkdsk C: /r  again.  (a user in reference #3)

That I did, and this time it ran without error and the issues was resolved.

The PC booted without any issue.
