XAdES4j is a 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.
The API provides a high level of abstraction, handling all the structural details of XAdES. The library relies on Apache XML Security for the core XML-DSIG processing and uses Guice to assemble the different configurable components.
The library is available on Maven.
