Is it safe to use obsolete TLS protocols?
“Using obsolete encryption provides a false sense of security because it seems as though sensitive data is protected, even though it really is not,” the agency added. Even if TLS 1.2 and TLS 1.3 are deployed, the NSA warns against configuring these two protocols with weak cryptographic parameters and cipher suites.
