Hi Tom,

> More a comment for crypto-types or keystore but I have not seen an e-mail about those lately.

I only found X.690 refs in the "crypto-types" and "sztp-csr” drafts.  Regardless...

> I see, courtesy of the RFC Editor, that X.690 has been updated to a 2021 version (which the RFC Editor would like to use).

> Any one know what the differences are?

I looked at the 2021 version here (https://www.itu.int/rec/T-REC-X.690), but it doesn’t contain a “difference to previous version” section.

I did find this (https://www.itu.int/en/ITU-T/asn1/Pages/Changing-from-ASN-119881990-to-ASN-12008.aspx), but it only covers the 1990 —> 2015 update.

> Assuming we know those, should we use it as  a reference?  Sometimes the new-fangled version of another SDO's work is not right for the IETF and we stay with the previous versions.

Firstly, we don’t know the changes…at least I don’t yet.

Second, I don’t believe the world of libraries and tools are going to flip overnight.   All the schema and compilers use the 2015 and, in some cases, I wouldn’t be surprised is the 1990 version was used.  For instance, note that  RFC 5280 was published in 2008!

My thoughts are to stay with 2015, at least until someone (ITU?) can provide a reasonable diff…

PS: X.680 was also just updated (https://www.itu.int/rec/T-REC-X.680)

<tp>
Kent 

Thanks for that.  As I said, it was the RFC Editor which was proposing the updated version to the authors of an  I-D so you may get a similar proposal in due course (by which time, we may know more about it).
