Values:

[.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, to enable several SSL versions use bitwise OR operation, for example ‘sbSSL2 | sbSSL3 | sbTLS1’.

    Example: The following shows how to set the property for different SecureBlackbox editions:

[C#]
TElSSLSocket.Versions = SBSSLConstants.Unit.sbTLS11 | SBSSLConstants.Unit.sbTLS12;

[VB.NET]
TElSSLSocket.Versions = SBSSLConstants.Unit.sbTLS11 Or SBSSLConstants.Unit.sbTLS12

[Pascal]
TElSSLSocket.Versions = sbTLS11 or sbTLS12;
