Verify Factura Electronica Chile SII (iso-8859-1)

See more XAdES Examples

Demonstrates how to verify SII XML stored as iso-8859-1 having just a single signature. Objective-C

#import <CkoStringBuilder.h>
#import <CkoXmlDSig.h>

BOOL success = NO;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// The signed XML to be verified in this example contains the following:

// <?xml version="1.0" encoding="ISO-8859-1"?>
// <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
// <Documento ID="F13T34">
// ...
// </Documento>
// <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
// ....
// </Signature>
// </DTE>

// Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1 
CkoStringBuilder *sbXml = [[CkoStringBuilder alloc] init];
success = [sbXml LoadFile: @"qa_data/xml_dsig/sii_cl/signed1.xml" charset: @"iso-8859-1"];
if (success == NO) {
    NSLog(@"%@",@"Failed to load input file.");
    return;
}

CkoXmlDSig *dsig = [[CkoXmlDSig alloc] init];

success = [dsig LoadSignatureSb: sbXml];
if (success != YES) {
    NSLog(@"%@",dsig.LastErrorText);
    return;
}

BOOL bVerifyReferenceDigests = YES;
BOOL bVerified = [dsig VerifySignature: bVerifyReferenceDigests];
if (bVerified == NO) {
    NSLog(@"%@",dsig.LastErrorText);
    return;
}

NSLog(@"%@%d",@"Signature verified = ",bVerified);
