The XAdES4j library is an high-level, configurable and extensible Java implementation of XML Advanced Electronic Signatures (XAdES 1.3.2 and 1.4.1). It enables producing, verifying and extending signatures in the main XAdES forms: XAdES-BES, XAdES-EPES, XAdES-T and XAdES-C. Also, extended forms are supported through the enrichment of an existing signature.

There is a newer version: 2.3.0

/**
 * Interface for property data objects marshallers.
 * 
 * The signed and unsigned properties are marshalled at a different time in the
 * signature production. The separation comes from the nature of the properties:
 * signed properties need to be marshalled before the signature so that they are
 * covered by a {@code Reference}. On the other hand, unsigned properties do not
 * need to be marshalled before the signature and most of the times they can't be,
 * because they use information that results from the signature generation.
 * 
 * Built-in implementations of signed and unsigned properties data objects marshallers
 * are based on JAXB and support all the signed properties data objects in the library
 * (XAdES 1.4.1) plus the {@code GenericDOMData}.
