Function SampleSigner(Code: String; PathKey: String): String;
Var
Package: ISecurityPackage;
Provider: ICertProvider;
FStream: IFileStream;
Signer: ICertSigner;
Signature: String;
Begin
Package := New StandardSecurityPackage.Create;
Provider := Package.CertProvider;
//Comparison of random value and block of data
Provider.Code(Math.RandBetweenI(Integer.MinValue, Integer.MaxValue).ToString) := Code;
FStream := New FileStream.Create(PathKey, FileOpenMode.Read, FileShare.DenyNone);
//Get signer
Signer := Provider.OpenSigner("sp", FStream);
//Digital signature
Signature := Signer.Sign(Code);
