# Stuff for Document Signing
|
|
|
|
This code provides dialogs, and infrastructure wrapping `libxmlsec` and
|
|
`gpgme` that implements document signing.
|
|
|
|
For signing a document, a personal key pair is used, which consists of a
|
|
private key and a public key, which is added to the document in addition
|
|
to the digital signature of the document, when signing it.
|
|
|
|
The document signing can be done both for the source ODF/OOXML files and
|
|
the exported PDF files. It is also possible to sign existing PDF files.
|
|
|
|
To test the signed PDFs, one can use the `pdfverify` in this way:
|
|
|
|
./bin/run pdfverify $PWD/xmlsecurity/qa/unit/pdfsigning/data/2good.pdf
|
|
|
|
The file parameter should be an absolute path.
|
|
|
|
This is the output of `pdfverify` for `2good.pdf`:
|
|
|
|
```
|
|

|
|

|
|

```
