GroupDocs.Signature provides the getDocumentInfo method of the Signature class to receive document information. The response IDocumentInfo includes:
- list of MetadataSignature objects (
getMetadataSignatures()) that for a certificate document keeps all its properties;
LoadOptions loadOptions = new LoadOptions();
loadOptions.setPassword("1234567890");
Signature signature = new Signature(certificatePath, loadOptions);
try
{
IDocumentInfo documentInfo = signature.getDocumentInfo();
System.out.println("Certificate properties " + new java.io.File(certificatePath).getName() + ":");
System.out.println(" - format : " + documentInfo.getFileType().getFileFormat());
System.out.println(" - extension : " + documentInfo.getFileType().getExtension());
System.out.println(" - size : " + documentInfo.getSize());
System.out.println(" - page count : " + documentInfo.getPageCount());
// display document MetaData signatures information
System.out.println("Certificate properties:");
for (MetadataSignature metadataSignature : documentInfo.getMetadataSignatures())
{
System.out.println(" - " + metadataSignature.getName() + ":" + metadataSignature.getValue() + " (" + metadataSignature.getType() + ")");
}
}
finally
{
signature.dispose();
}
The GetCertificateInfoAdvanced class of the Java examples runs this code for a .pfx certificate.
