[.NET] [Pascal] [ActiveX] [DLL] Description

sbSSL2 = 1 sbSSL2 SB_SSL_2 = 0 SSL version 2

sbSSL3 = 2 sbSSL3 SB_SSL_3 = 1 SSL version 3

sbTLS1 = 4 sbTLS1 SB_TLS_1 = 2 TLS version 1

sbTLS11 = 8 sbTLS11 SB_TLS_11 = 3 TLS version 1.1

Namespace: SBConstants
Assembly: SecureBlackbox Unit: SBConstants

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.
    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:

[C#]
ElAS3SSLOptions.Versions = SBConstants.Unit.sbSSL2 | SBConstants.Unit.sbSSL3 | SBConstants.Unit.sbTLS1;

[VB.NET]
ElAS3SSLOptions.Versions = SBConstants.Unit.sbSSL2 Or SBConstants.Unit.sbSSL3 Or SBConstants.Unit.sbTLS1

[Pascal]
ElAS3SSLOptions.Versions = sbSSL2 or sbSSL3 or sbTLS1;
