[.NET]	[Pascal]	[C++]	Description
sbSSL2 = 1	sbSSL2	f_sbSSL2 = 1	SSL version 2
sbSSL3 = 2	sbSSL3	f_sbSSL3 = 2	SSL version 3
sbTLS1 = 4	sbTLS1	f_sbTLS1 = 4	TLS version 1
sbTLS11 = 8	sbTLS11	f_sbTLS11 = 8	TLS version 1.1
sbTLS12 = 16	sbTLS12	f_sbTLS12 = 16	TLS version 1.2
f_sbTLS13 = 32	sbTLS13	sbTLS13 = 32	TLS version 1.3 (RFC 8446)

Description

This property defines which SSL/TLS versions are allowed to be used during SSL/TLS session. By default all versions are allowed. The application can disable undesired versions. It is not possible to disable SSL3 if TLS1 and SSL2 are both enabled.
Note, If you set Versions to [sbSSL3, sbTLS1] and connect to Java 2 server which supports only TLS1, Java server will crash. This is a bug in Java 2 server.
