fstTLS12

fstTLS12 = 3

Example

procedure ConfigureTLS12(Client: TvxHTTP);
begin
  Client.SSLClientType := fstTLS12;
end;

Usage

fstTLS12 selects Velox's TLS 1.2 method and is the clear current member for an explicit TLS 1.2 Velox client configuration.

Additional Technical Info

fstTLS12 is ordinal 3 of TvxSSLClientType and maps directly to sslvTLSv1_2. It is also the normalization target for legacy fstTLS1_2. Unlike Auto/TLS13, its name matches the current mapping.

Use it when the integration contract explicitly requires TLS 1.2. It does not enable TLS 1.3 and does not by itself prove certificate-chain/hostname verification, trusted roots, acceptable ciphers or runtime library patch level. Review peer-verification settings and validate the deployed wire connection during the later test-bed stream.

The example only configures the member and was source-reviewed; no TLS/network/certificate/runtime/image test ran.
