There are a lot of SSL protocols. FIXEdge supports SSL v2.0, SSL v3.0, TLS v1.0, TLS v1.1, TLS v1.2, TLS v1.3. By default only TLS v1.0, TLS v1.1, TLS v1.2,TLS v1.3 protocols are enabled in FIX Edge.
| Note |
|---|
| It's highly recommended to use TLS v1.1, TLS v1.2, or TLS v1.2 3 protocol because SSL protocol versions were deprecated (see: Deprecating SSL v3.0 ) |
| Note |
|---|
Recommended TLS 1v1.1 and , TLS 1v1.2 or TLSv1.3 protocols are supported only by OpenSSL version 1.0.1 and higher (see: https://www.openssl.org/news/changelog.html ). |
