== February 2022 CA Communication == | |||
Dear Certification Authority, | |||
Mozilla is engaged in policy review discussions to sunset the use of SHA1 for signing by CAs of CRLs, OCSP responses, and SMIME certificates. | |||
See https://groups.google.com/a/mozilla.org/g/dev-security-policy/c/CnVjV-bFcyI/m/TFuWOy2BAwAJ | |||
(Server certificate signing is governed by the Baseline Requirements, and effective June 1, 2022, OCSP responses related to server certificates cannot be signed with SHA1.) | |||
One proposal is to remove SHA1 from the list of allowed signing algorithms altogether, but before we do this, I would like your proposed sunset dates for the different types of SHA1 signing you might currently perform--SMIME certificates, ARLs/CRLs, and OCSP responses for SMIME certificates. | |||
Please participate in this important topic, which is already underway on the Mozilla dev-security-policy list. Let us know about your specific concerns and hurdles that would need to be overcome. | |||
(Some CAs have expressed willingness to quickly convert over to SHA256, while others have expressed that it is not a simple task and will require additional development work.) | |||
Thanks, | |||
