Hi Stefan, https://github.com/FreeRDP/FreeRDP/blob/2.0.0/ChangeLog "sha256 is now used instead of sha1 to fingerprint certificates." - sha1 is considered insecure in general. You can also question whether self-signed certs are secure at all.. i.e. you are definitely better of using trusted certificates and training your end users to cancel any connections with certificate warnings/errors. Good to know some distros pick up 2.0.0. Best Regards, Joachim
