关于数字签名

You must save a file before you can apply a digital signature to the file.

You must save a file in OpenDocument format or OOXML format or export to PDF before you can apply an X509 digital signature to the file. You must save a file in OpenDocument format and have GnuPG installed on your system before you can apply an OpenPGP digital signature to the file.

The signature will be a XAdES signature for ODF and OOXML, PAdES signature for PDF.

On macOS, the default certificate manager is Keychain Access.

On Windows systems, the default certificate manager is Certmgr.msc, a Microsoft Management Console snap-in using Certmgr.exe, and does not manage OpenPGP certificates. To manage both X509 and OpenPGP certificates install the gpg4win tool.
