I have a Lenovo laptop and had the superfish root cert installed. I also have a "Nuance" trusted root certificate installed. It's a SHA1RSA certificate issued by Nuance, expiring in January 2040 (serial 9e ef 9d f5 9a...), thumbprint (51 2d 19 4d 28 64...). It says it's usable for everything. Does anyone know about this one?
