To export an X.509 certificate using the Windows Terminal or Command Prompt, you can use the certutil command. If you're encountering an error related to the -file option, it's possible that you are not using the correct syntax or the option is not supported.

Here's the correct syntax to export an X.509 certificate using certutil:

bash
certutil -exportPFX -user -p <password> <certSerialNumber> <exportedFilename>.pfx

Replace the placeholders:

  • <password>: Replace with the password to protect the exported .pfx file.
  • <certSerialNumber>: Replace with the serial number of the certificate you want to export.
  • <exportedFilename>: Replace with the desired filename for the exported .pfx file.

For example, to export a certificate with serial number 12345678 to a file named mycert.pfx with password mypassword, the command would be:

bash
certutil -exportPFX -user -p mypassword 12345678 mycert.pfx

Make sure you're running the command in an elevated Command Prompt or Windows Terminal with administrative privileges.

If you're still encountering issues, please provide more details about the error message you're seeing or any specific scenarios you're dealing with.
