ISSUE-52: Rules for syntax of KeyInfo child elements should be unambiguous

clarify keyinfo

Rules for syntax of KeyInfo child elements should be unambiguous

State:
CLOSED
Product:
XML Signature Best Practices
Raised by:
Scott Cantor
Opened on:
2008-09-15
Description:
In at least one case (X509Certificate), work in another SDO that references the XML Signature specification is being questioned on the basis of whether or not the syntax of the element is clearly defined or not. For example, it says base64, but doesn't come out and actually say "of what". Is anything other than the DER encoding legal? Etc.

Related notes:

Suggestion after discussion was to add text to the BP document to explicate the kinds of certificate formats that one tends to use, and any issues related to interop there.

Text to help explain the ds:CryptoBinary vs. xsd:base64Binary distinction for key values might also be helpful.

See BP 18, XSig 1.1 4.4.4.
