Encrypting documents in XPiNC

Image:Encrypting documents in XPiNC

One of the nice things that sets XPiNC ( XPages in the Notes Client ) apart from XPages in the browser is the ability to encrypt documents using the native Notes encryption mechanisms.

I’ve just been working on a Proof of Concept for a proposal and had a few issues getting it to work so here are some notes :

> The encryption settings on the underlying form for the data source seem to have no impact at any time.

> You need to uses SSJS to programmatically set the encryption key for the document, the isEncrypted() property on the document and the isEncrypted() property on the field ( NotesItem ).

> When accessed via the browser the download control appears as empty

> When you access it via XPiNC without the certificate the download control appears empty

> There is some guidance from IBM at the links below but it is not great. Note that the method of setting the NotesItem.IsEncrypted property is setEncrypted(true) and not .IsEncrypted = true


> You need to keep resetting the properties when you save the document otherwise it becomes un-encrypted.

> I added this code to my save button where the field test is used for attachments and the encryption certificate is called “commercial info”
