CryptoApplet is a Java applet for advanced digital signature creation developed by the Universitat Jaume I. The procedure is very simple: given a data input and a configuration determined by the server, the web client will create a digital signature of the data. The representation of the signature is obtained in the format specified in the configuration.

The signature representation formats supported by CryptoApplet are the following:

• Raw signature.
• CMS/PKCS#7.
• XML: from XML Signature to XAdES-X-L.
• PDF: PAdES signature with timestamp.
• ODT: XML Signature.

Certificate management is done transparently for the user through direct access to CryptoAPI, if we are using Microsoft Internet Explorer, or to PKCS#11 if we are using Firefox (either in Windows or GNU/Linux). Stored certificates can also be used if the client system has the Clauer software installed.

The applet can also be executed in Windows, GNU/Linux or MacOSX, the only requirement is to have a Sun's Java Virtual Machine (version 1.6 o higher) installed.
