How to set Signature 'DigestMethod' algorithm using OpenSAML

[Dulanja Liyanage]

Hi,

We can set the signature algorithm as following using OpenSAML:

signature.setSignatureAlgorithm("
> http://www.w3.org/2001/04/xmldsig-more#rsa-sha256");


I'm trying to find a way to set the DigestMethod algorithm like that. The
only way to do that seems to be :

BasicSecurityConfiguration config = (BasicSecurityConfiguration)
> Configuration.getGlobalSecurityConfiguration();
>
> config.setSignatureReferenceDigestMethod(SignatureConstants.ALGO_ID_DIGEST_SHA256);


However, that's a global configuration. In my application we bootstrap
OpenSAML only once and then used by different threads with different
configurations - like different signature algorithms. Is there a way to do
this in a thread-safe manner like the Signature Algorithm?

Appreciate your inputs on this.

Thanks,
Dulanja
