Update: Yes.
To one of these: Nope.
   Use RFC 4648 for base64 outside the narrow scope of email/MIME !
   (But triply cross-check the line length and folding requirements!)

>  o  Current registry: SHA link (

Yes.  (Increase the utility of the registry for its users.)

>     or RFC3174?

If you want to be conservative, use RFC 3174;
otherwise point to the current version of the SHS, FIPS 180-3.

Since the latter is a current standard, other WGs in the IETF
now are used to quote FIPS 180-3, e.g. PKIX, SMIME, TLS, etc.

Doing so has the additional benefit of re-using the citation
needed for the SHA-2 family anyway, keeping the draft shorter!  :-)


Btw: Can you avoid that weird line folding in the Ref. entry [SHS]:

|                                                    <htt
|   p://csrc.nist.gov/...


Kind regards,
  Alfred H╬nes.
