The IESG has approved the following document: - 'Cryptographic Algorithm and Key Usage Update to DKIM' (draft-ietf-dcrup-dkim-usage-06.txt) as Proposed Standard This document is the product of the DKIM Crypto Update Working Group. The IESG contact persons are Adam Roach, Alexey Melnikov and Ben Campbell. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dcrup-dkim-usage/ Technical Summary The cryptographic algorithm and key size requirements included when DKIM was designed in the last decade are functionally obsolete and in need of immediate revision. This document updates DKIM requirements to those minimally suitable for operation with currently specified algorithms. Working Group Summary There were two points which were discussed at length, but consensus was reached and is appropriately reflected in the document. Additional concerns have been moved to other documents. Document Quality This has received security and DKIM community participation. No further expert reviews are warranted. This document removes obsolete protocol elements from a widely deployed and understood standard. Personnel Seth Blank is the Document Shepherd, and Alexey Melnikov is the responsible Area Director.
