Specifies the allowed SSL/TLS versions.
Declaration
TSBVersions Versions;
TSBVersions = short;
TSBVersions represents a bit mask which contains zero or more bit flags as defined by TSBVersion

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.
Default value is
[sbSSL2, sbSSL3, sbTLS1, sbTLS11].
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.
Note, protocol version assigning differs in VCL and .NET versions.
To enable some SSL versions in .NET use bitwise OR operation, for example ‘sbSSL2 | sbSSL3 | sbTLS1’.
Example: The following shows how to set the property for different SecureBlackbox editions:
TElSSLClient.Versions = SBConstants.Unit.sbSSL2 | SBConstants.Unit.sbSSL3 | SBConstants.Unit.sbTLS1;
TElSSLClient.Versions = SBConstants.Unit.sbSSL2 Or SBConstants.Unit.sbSSL3 Or SBConstants.Unit.sbTLS1
TElSSLClient.Versions = sbSSL2 or sbSSL3 or sbTLS1;
