|1||Rainer Hoerbe||NA||The first paragraph in the introduction should contrast the deployment profile with an implementation profile, and reference the SAML Implementation Profile for Federation Interop for this purpose. The difference between both types of profiles is not widely understood.|
|2||Rainer Hoerbe||SDP-MD02||I do not understand the explanation for [SDP-MD02]. If PKI with path validation is being used, there would be no hindrance to roll out new keys, even if metadata and assertions use the same key. I have seen a IDPs that publish their own metadata and the well-know location using the same signing key as for assertions.|
I think you may be correct about that and that the text is written with a presumption of the verification approach, and if we didn't specify that (and I don't think we did), it's open to methods that wouldn't have the problem we were concerned about. I think it needs work. Good catch.
|4||Rainer Hoerbe||SDP-SP23||I think that the division of IDP-discovery into disco-UI and preference persistence is a significant improvement over the current IDP-Discovery spec, fixing the issue that embedded discovery results are not shared across SPs. See the RA21-proposal: https://groups.niso.org/apps/group_public/download.php/21376/NISO_RP-27-2019_RA21_Identity_Discovery_and_Persistence-public_comment.pdf. Rumor has it that Leif implemented it in pyFF.|
(Scott) The discovery spec that's referencing never addressed UI or persistence, it's an interop protocol only, to enable a discovery solution to be injected into the flow, whatever solution it might be.
I'm trying to understand the RSA-OAEP encryption requirements for IdPs / SPs.
It seems most IdPs use SHA1 for both the MFG1 and digest? So, this profile requires you to use SHA1 for the MFG1 and SHA256 for the digest. Any reason why it is not SHA256 for both?
Also, why not require MGF1 with SHA256:
Probably I am missing something here...
(Github Issue #129)
I read the parenthesized reference to the default mask generation function to be a reiteration of a requirement stated elsewhere, particularly XMLEnc's §5.4.2 statement that "As described in the EME-OAEP-ENCODE function RFC 2437 [PKCS1, section 22.214.171.124], .... using the mask generator function MGF1 (with SHA1) specified in RFC 2437."
If i am correct, i wonder if rewording as follows would be more clear
