The IESG has received a request from the DKIM Crypto Update WG (dcrup) to consider the following document: - 'Cryptographic Algorithm and Key Usage Update to DKIM' <draft-ietf-dcrup-dkim-usage-04.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2017-09-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract 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 minimaly suitable for operation with currently specified algorithms. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dcrup-dkim-usage/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dcrup-dkim-usage/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc8017: PKCS #1: RSA Cryptography Specifications Version 2.2 (Informational - IETF stream)
