I'm busy revising for an exam on xml and web services and i'm going over a few past papers. Answered a few questions but i'm not sure if my answers are correct.

To start with:

Q: Which key is used to encrypt data when creating a digital signature

A: Private Key


Q: Which key is used to encrypt data that is only to be read by a specific party?

A: Public key

Correct or have I got them the wrong way round?

Secondly, i've trawled through the lectures to find the answer to this question, but I'm not sure if i've found the right information:

Q: In terms of the XML document tree, briefly describe the four ways by which the signature is related to the location of the content being signed?

A:

Enveloped – where the signature is carried along within the data (as a child element)
Enveloping – the inverse of enveloped, where the data being signed is carried within the signature (as a parent element)
Detached – Where the data being signed is somewhere else (identified by a URI)
It can also reside within the same resource (as a sibling element)

Have I got the right four things or am I completely barking up the wrong tree?

Help is welcomed as I don't want to constantly bug my lecturer all day!

Will probably add more as I go on :)

Can't speak for the second lot but the first two are correct
