Here’s a simplified example using Base64 encoding (not secure alone – always use encryption in real apps):
function ValidateActivationFile(const FileName: string): Boolean; var Lines: TStringList; Decoded, MachineIDPart, HashPart, CalculatedHash: string; Parts: TArray<string>; begin Result := False; if not FileExists(FileName) then Exit; Lines := TStringList.Create; try Lines.LoadFromFile(FileName); if Lines.Count = 0 then Exit; Decoded := TNetEncoding.Base64.Decode(Lines[0]); Parts := Decoded.Split(['|']); if Length(Parts) < 3 then Exit; file activation delphi 2016
// Optional: Check expiration date if StrToDateDef(Parts[2], 0) < Now then Exit; Here’s a simplified example using Base64 encoding (not
