Re: Fw: [saml-dev] Question about the base64 encoding in Browser/POST profile

Good Question.

When you decode the B64, the prolog of the XML document which defines the
encoding should be in ASCII.  This will allow you to get the underlying
encoding of the decoded B64.

the B64 it could be anything from UTF8 to binary, couldn't it? or is this
even necessary?
