That seems to be the case. Maybe (2) needs an update to enable newer ciphers, when logging the mappings I see there are quite a few IDs which don't get mapped: TlsDxe:TlsSetCipherList: skipping CipherId=0x1302 TlsDxe:TlsSetCipherList: skipping CipherId=0x1303 TlsDxe:TlsSetCipherList: skipping CipherId=0x1301 TlsDxe:TlsSetCipherList: skipping CipherId=0x1304 TlsDxe:TlsSetCipherList: CipherId=0xC030 -> ECDHE-RSA-AES256-GCM-SHA384 TlsDxe:TlsSetCipherList: skipping CipherId=0xCCA8 TlsDxe:TlsSetCipherList: skipping CipherId=0xC014 TlsDxe:TlsSetCipherList: skipping CipherId=0xC02F TlsDxe:TlsSetCipherList: skipping CipherId=0xC013 TlsDxe:TlsSetCipherList: skipping CipherId=0xC012 TlsDxe:TlsSetCipherList: CipherId=0xC02C -> ECDHE-ECDSA-AES256-GCM-SHA384 TlsDxe:TlsSetCipherList: skipping CipherId=0xC0AD TlsDxe:TlsSetCipherList: skipping CipherId=0xCCA9 TlsDxe:TlsSetCipherList: skipping CipherId=0xC00A TlsDxe:TlsSetCipherList: CipherId=0xC02B -> ECDHE-ECDSA-AES128-GCM-SHA256 TlsDxe:TlsSetCipherList: skipping CipherId=0xC0AC TlsDxe:TlsSetCipherList: skipping CipherId=0xC009 TlsDxe:TlsSetCipherList: skipping CipherId=0xC008 TlsDxe:TlsSetCipherList: skipping CipherId=0x009D TlsDxe:TlsSetCipherList: skipping CipherId=0xC09D TlsDxe:TlsSetCipherList: CipherId=0x0035 -> AES256-SHA TlsDxe:TlsSetCipherList: skipping CipherId=0x009C TlsDxe:TlsSetCipherList: skipping CipherId=0xC09C TlsDxe:TlsSetCipherList: CipherId=0x002F -> AES128-SHA TlsDxe:TlsSetCipherList: CipherId=0x000A -> DES-CBC3-SHA TlsDxe:TlsSetCipherList: CipherId=0x009F -> DHE-RSA-AES256-GCM-SHA384 TlsDxe:TlsSetCipherList: skipping CipherId=0xC09F TlsDxe:TlsSetCipherList: skipping CipherId=0xCCAA TlsDxe:TlsSetCipherList: CipherId=0x0039 -> DHE-RSA-AES256-SHA TlsDxe:TlsSetCipherList: skipping CipherId=0x009E TlsDxe:TlsSetCipherList: skipping CipherId=0xC09E TlsDxe:TlsSetCipherList: CipherId=0x0033 -> DHE-RSA-AES128-SHA TlsDxe:TlsSetCipherList: CipherId=0x0016 -> DHE-RSA-DES-CBC3-SHA TlsDxe:TlsSetCipherList: skipping CipherId=0x00A3 TlsDxe:TlsSetCipherList: skipping CipherId=0x0038 TlsDxe:TlsSetCipherList: skipping CipherId=0x00A2 TlsDxe:TlsSetCipherList: skipping CipherId=0x0032 TlsDxe:TlsSetCipherList: skipping CipherId=0x0013 > Can you perhaps relax your crypto policy -- i.e., widen set (1) -- to > LEGACY with "update-crypto-policies", to see if that makes a difference? > > (Or else, on the QEMU command line, use a different priority from > @SYSTEM; but I'm not sure how that works.) https://gnutls.org/manual/html_node/Priority-Strings.html Tried @SYSTEM, DEFAULT and LEGACY, none of them work.
