On Windows systems, LibreOffice will access the system certificate storage.
Your private key for the digital signature will usually be generated and securely stored by Windows as part of the signature-issuance process. Once the issuing Certificate Authority is satisfied that your computer produced the private key and you have satisfied any other identification requirements, the corresponding public key is signed by the Certificate Authority. For personal keys obtained over the Internet, the private key is generated by your browser and it is not shared with the Certificate Authority.
If a private key is received by other means or you transfer it from another computer, you can install it on your Windows PC by double-clicking on the private key certificate and providing any required password. This private key may be known to others (such as an organizational or governmental security administration) depending on how it was issued to you.
Public keys of other people used to verify document digital signatures, or encrypt documents for their eyes only, are usually stored in your system with digital certificate-management applications. In some cases you will need to manage those public-key certificates yourself.
The general management of public and private keys on your PC will vary depending on the version of Windows you are operating. For more information, use the "Help and Support" topic of your Windows version and search for "digital signature".
