Description: What TLS versions are supported by EMS?
Symptoms: N/A
Cause: N/A
Issue/Introduction
TLS versions supported by EMS.
Resolution
EMS 5.x, 6.x up to 8.2, rely on OpenSSL 0.9.8 which supports TLS 1.0.
EMS 8.2.2 relies on OpenSSL 1.0.1p. EMS 8.2.2 does not fully support TLSv 1.2 protocol and ciphers. EMS 8.2.2 only supports TLS 1.0. But EMS 8.x can work with SHA-2 signed certificates. Since EMS 8.0, EMS sample certificates are SHA-2 signed certificates.
EMS 8.3 relies on OpenSSL 1.0.2f. It is fully tested with TLSv 1.2 protocol and ciphers. It supports both TLS 1.2 and TLS 1.0.
