fstTLS1_1

fstTLS1_1 = 8

Example

function IsLegacyTLS11Name(const Value: TvxSSLClientType): Boolean;
begin
  Result := Value = fstTLS1_1;
end;

Usage

fstTLS1_1 retains a legacy underscore name whose direct mapping is TLS 1.2 but whose setup/transport transfer normalization changes it to TLS 1.1.

Additional Technical Info

fstTLS1_1 is legacy ordinal 8 of TvxSSLClientType, displayed only as old. Its direct IndySSLTypeArray entry is unexpectedly TLS 1.2. However, Setup and Transport transfer/copy code normalizes it to fstTLS11, which maps TLS 1.1.

The effective protocol can therefore depend on whether the value is used directly on a local client or passes through a product transfer path. Do not use it in new scripts/configuration and do not infer protocol from the legacy name. Migrate explicitly to fstTLS12 for current TLS 1.2 or, only for a documented legacy dependency, fstTLS11.

The example only identifies configuration and was source-reviewed; no TLS/transfer/network/runtime/image test ran.
