Subject: Re: AW: [dss-x] A question to the forum

Hmm, I would recommend to just leave it to the server ...
There may be tricky cross dependencies if you provide ready-made digest with a different algorithm. Whta if this is different from the one denoted to be used ?
And what should the digest algorithm apply for ? For the document hashing or the signature internal hash ? 
Should it be a hint or an advice ? What type of error should be returned in case of an incompatibility ?

Hallo Ezer,
in my point of view the explicit specification of the hash algorithm to 
be used for the signature generation is very similar to the explicit selection of 
a specific key (and hence implicitely signature algorithm + hash algorithm), 
if there are multiple options available. Therefore I would propose to use the 
KeySelector-structure (section 3.5.4 of the Core) and simply define structures, 
which may appear in the Other-element. 
What do think about this approach?

I went over the DSS-core and could not find a way to direct the server to use a certain hash mechanism when performing a CMS signature or XML signature on a given document.
(When a hash is given it is possible to use the DigestMethod or the relevant given hash).
Did anyone bump into such a request?
