Standardised Signature

Signature system based on the client launching a module called JNLP (Java Network Launch Protocol). This module will be downloaded when you start the signature process and will run associated with the Java Web Start program, so you must have the Java virtual machine installed in the system. It is widely compatible with the most famous browsers.

Compatibility table

Note: Firefox is only compatible with its 64 bit version, but it also requires the certificate to be installed in the Operating System certificate store so using other browsers is recommended.

NON-Standardised Signature Type 1

Note 1: This type of signature is not currently supported in the new version of Java 9.xx

Note 2: At the moment, this type of signature is not compatible with Firefox version 56 or higher  on 64-bit operating systems.

Social Security is committed to an application development standardisation process. This means that various electronic signature systems are currently in use:

  • Already standardised applications, such as the one based on the Java Network Launch Protocol (JNLP) or based on the cloud signature type belonging to the Permanent Cl@ve system.
  • Applications not yet standardised, which maintain the Java applet based signature system or which use signature extensions for browsers such as CryptoBrowser.

Check the following document to find out which type of signature each service uses.
