Library to manage XAdES signatures in Java [closed]
We have recently completed a project using XAdES-BES signatures in both enveloped and enveloping forms. We chose the XAdES4j project because it seemed the most complete, and XAdES was a core requirement.
The support on the Q&A section is sometimes slow, and and only the most obvious use case is well documented. That said the library is well tested, excellently designed, and very useful.
We spent a couple of weeks getting our heads around it and I would now recommend it as a platform.
The only caveat is that (as you say) it is the production of an academic project, so how much support it will receive in the future is anyone's guess. If you pick it up and buy into it then consider contributing, and it might pick up a bit of speed.
You can look at the "Componentes de firma", a LGPL suite of components created and mantained by the Spanish government. It's a full cryptographic suite that supports creation and validation of the following XAdES formats:
- XAdES-BES
- XAdES-T
- XAdES-C
- XAdES-X
- XAdES-XL
- XAdES-EPES
With detached, enveloped, enveloping and mixed signatures.
Detailed description of the XAdES signatures can be found at http://oficinavirtual.mityc.es/componentes/MITyCLibXADES/index.html, and the download site is http://oficinavirtual.mityc.es/componentes/downloads.html
Just to complete the list, XMLBlackbox package of our SecureBlackbox (Java edition) offers full support for all XAdES versions and is actively maintained and supported.
