In general, anything that is using TLS standard below TLS 1.2 is considered to be non secure because these older encryption algorithms are known to be cracked.Īpparently, the provider of the API I was trying to call disabled all other security protocols except for TLS 1.2. At the moment TLS 1.2 is a latest encryption standard powering SSL and TLS 1.3 is in works. TLS standards keep developing and improving. However, after some digging around I realized that the error message was correct, at least in the following part: “ This could also be caused by a mismatch of the security binding between the client and the server.” I checked my SOAP bindings, and everything seemed to be correct: server required SSL connection, and I had TransportLevelSecurity specified in my binding: var binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport) Īfter I read more about SSL and Transport Level Security (TLS), I understood that “not all HTTPSs are created equal.” HTTPS relies on a family of lower level security protocol implementations called transport level security (TLS), each using different cryptographic algorithms.
