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: 2.4.0
