This tool allows you to add a digital signature to any kind of documents.

• Be sure that the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files are installed in your Java folder.
• To start/download the JSigner application click on the icon.
• The application creates two commands (PDFSignerJWS and PKCS7SignerJWS) that you can find under the "Send to" context menu of your Windows Explorer.
• To sign a document you need a personal e-mail certificate (http://www.cacert.org/).
• The first time you run the application, it will ask you for the standard certificate you want to use.

PKCS7SignerJWS could be used to sign all kind of files.

• Right mouse click on your document --> Send to --> PKCS7SignerJWS. A new window will open asking for the password of the selected certificate.
• After you click OK, a new document will appear with the same name as your original document + p7s suffix. This file is the signature of your original file. The original file and the signature should be saved in the same folder. Don't rename the files!
• Using a signature reader software (for example digiSeal reader) you can check the signature and the status of your document.

PDFSignerJWS should be used to sign pdf files.

• Right mouse click on your document --> Send to --> PDFSignerJWS. A new window will open asking for the password of the selected certificate.
• After you click OK, a new document will appear with the same name as your original document + 000 suffix. This file is a unsigned backup of your original file. The original file is now signed.
• Once the pdf file is open you will see at the bottom an icon with the signature.
