Hi Wayne, Good day.
Regarding the certificates you mentioned, for CFCA: - sha256 Fingerprint=6E:6E:B2:9F:5E:BA:91:0A:FF:D4:62:FC:92:1D:72:4E:52:68:05:EF:E9:08:AE:C4:5B:D4:09:B6:24:E1:4C:09 this is a root certificate, it's not in violation with MRSP 5.3 - sha256 Fingerprint=FA:A4:FA:0E:F7:05:6D:69:53:BB:DF:B3:64:61:E3:F7:CD:F3:33:52:AF:72:4F:D8:25:4B:18:4D:3E:2C:94:1F this is a cross certificate signed by CFCA EV ROOT, and within the 'exception' of MRSP 5.3. I've just checked BR, it seems not in violation with BR/MRSP. Let me know if you have any other concerns.
