read NSF files

Does anyone have a wrapper class for reading NSF files?
Watch Question

That's a pretty general question. Java class?
Can you explain what exactly do you want to do?

In order to read NSF files, you would need the Java libraries that are installed as part of a Lotus Notes or Lotus Domino server installation. Without this installation you can's read NSF files. For example, you can include Notes.jar in a Java project. See an example at



I was not aware of the Java libraries for Notes. Thanks for the info!
I guess I should have included more specifics in my question. I was wondering if anyone knew of a .NET wrapper around the C API. The COM object doesn't (to my knowledge) allow you to remove local security from an NSF file. You can with the C API and I was hoping to incorporate that functionality into my .NET code.

Remove local security from an NSF file?? Using the C API?? No way.


Are you sure? Then how do the third party guys do it? Like these guys:

Oh, if they do what I think they do, it's a (not so) well-known hack to remove one bit in the database. That bit indicates the setting for Enforce consistent ACL across all replicas. Once that bit is removed on a LOCAL database, anyone with a VALID Notes-id can open that database. But that won't say that they can read all documents; well, they can read them, but the encrypted documents will not be decrypted.

So essentially, you're right, and I have to correct myself: you can "break" local security but you can't break encryption.


Makes perfect sense. For some reason I thought it was a function of the C API. Would you be able to share the hack so I can test it? I have some databases with local security. The encryption part is OK, all I need to do is report on which documents can and can't be read and extracted, if it's encrypted it's encrypted!
