[xmlsec] How to encrypt only some Subnodes?

[Aleksey Sanin]

I think you already canceled your question but ... :)

You simply create the necessary template "subtree" encryption
and then specify that this "subtree" should replace the content
of the subtree you want to encrypt. There are examples of doing
this in the sources tarball and on the website.

Best,

It seems that function xmlSecTmplEncDataCreate() creates an EncryptedData node on the root, followed by some other functions that creates CipherValue and KeyInfo. But what can I do if I only want to encrypt 2 or 3 subnodes and not the whole document?

But how can I add the encryption nodes on this position? (Function xmlSecTmplEncDataCreate() doese not offer a parameter xmlNodePtr_TargetNode to specify the place where the encryption should start.)
