Firstly, read Section 4.3.1.17 of the OOXML spec which describes the
Modification Verifier element. You are going to set raw xml properties
via XmlBeans and you should understand what they mean.
Setting modifyVerifier is easy:
CTPresentation pr = ppt.getCTPresentation();
// get or create the modifyVerifier bean
CTModifyVerifier p = pr.isSetModifyVerifier() ?
pr.getModifyVerifier() : pr.addNewModifyVerifier();
// set document protection. Sample values are taken from the OOXML docs
//the class of cryptographic algorithm used by this
protection. Always HASH
p.setCryptAlgorithmClass(STAlgClass.HASH);
// the type of cryptographic algorithm used by this
protection. Always TYPE_ANY
p.setCryptAlgorithmType(STAlgType.TYPE_ANY);
// the cryptographic hashing algorithm
p.setCryptAlgorithmSid(4); // SHA-1
// the hash value for the password.
p.setHashData("9oN7nWkCAyEZib1RomSJTjmPpCY="); //
You will have to use the full ooxml-schemas.jar instead of
poi-ooxml-schemas.jar. You can build it yourself from POI svn or
download from the Maven central repo:
