Is ECDSA S/MIME signature generation available in Thunderbird? [using one of the Suite B curves]
I've tried using a PKCS#11 module that I am developing and ran into trouble with Thunderbird erroring out w/ "Unable to sign message. Please check that the certificates .... are valid and trusted." (which they are according to the certificate dialog which lists them as valid for Email Signing...) I have successfully performed ECDSA-based client-authentication in the latest Firefox release, but the code flow is quite different. -- dev-tech-crypto mailing list dev-tech-crypto@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-tech-crypto
