SHA3 support

Hi, I remember i tried 7y. ago a email certificate signed with SHA3, it was not OK. I tried again now, and it is still blocked. 1) the certs can be added in the account settings > S/MIME for signature and ciphering, with a warning. 2) then creating a new email, the recipients certificates are not detected (while configured in another account on the same thunderbird client), and forcing ciphering is not allowed with the error message "Sending of the message failed. This message cannot be digitally signed because the signing certificate selected in your End-to-End Encryption settings is not valid for this operation. (The certificate was signed using a signature algorithm that is disabled because it is not secure.)" "Unable to save your message as a draft. This message cannot be digitally signed because the signing certificate selected in your End-to-End Encryption settings is not valid for this operation. (The certificate was signed using a signature algorithm that is disabled because it is not secure.)" Even, when using only ciphering, and no signature in S/MIME. The parameter mail.smime.accept_insecure_sha1_message_signatures do not change the bahavior. -> Can Thunderbird allow SHA3 usage, please ? Even if thunderbird does not want to generalize it, mozilla may create a parameter by default false mail.smime.accept_sha3_message_signatures Best Regards, Gwenolé
