# # * * INTRODUCTION * *

FirmaXadesNet is a bookshop written in C # per.NET 5.0 for creation
XAdES signatures.It was carried out by the Department of New Technologies.
the Urban Planning Department of the Spanish Municipality of Cartagena (Murcia).
It is based on a modification of the XAdES starter kit developed by Microsoft
France.

# # * * CHARACTERISTICS * *

— Signature creation of XAdES-BES, XAdES-EPES, XAdES-T y XAdES-XL.

— Use of all types of certificates supported by Windows, including on
Smart Card, Token Usb, CNS

— Supported formats:Externally detached, Internally detached,
Degreped, Enveloping.

— Validation of Certificates via Authority OCSP or revocation lists.

— Support from co-signatories and counter-signatories.

— Support of RSA-SHA1, RSA-SHA256 and RSA-SHA512.

Within the solution there is a project with examples of use
bookshop.Some of the examples use the ACCV timestamp server
(Agencia de Tecnología y Certificación Electrregistering, Spain).

As an example to start the TextFirmaXades project, which allows
sign the Xml files digitally.

* * example of Enveloped signature use: * *

THE FOLLOWING:
IF (string.IsNullOrEmpty (nomeFileXml))
THE FOLLOWING:
MessageBox.Show (‘Xml is not ready for signature.’);
return;
BULL.

//Test SignatureCommitment
VaR sc = New SignatureCommitment (SignatureCommitmentType.ProofOfOrigin);
parametri.SignatureCommitments.Add (sc);

parametri.SignaturePackaging = SignaturePackaging.ENVELOPED;

using (parametri.Signer = new Signer (CertUtil.SelectCertificate))
THE FOLLOWING:

THE FOLLOWING:
