Digital signature, although slowly, is gaining ground over conventional signature. Mainly, it is used by the Spanish public administration, to sign employment contracts, and even it is being introduced to sign Real-State purchase agreements. It seems to be a trend because companies from different sectors are demanding this service more and more over time. This is because digital signature helps to speed up business performance. On the other hand, in 2014 Google decided to withdraw its support in its browser to Netscape Plugin Application Programming Interface, a technology that was very used for executing little applications integrated into the webpages and allowed doing any kind of cryptographic operations. Besides, it seems this decision taken by Google has become a trend, and other companies are doing the same with their own browser. This situation has lead to the need to look for new technologies for replacing it. In this project, we have evaluated differents architectures weighing up their advantages and disadvantadges, and haveistudied the best solution for Isigma, a company that offers digital signature services. In order to do that, we have taken into account their implementation viabilityand their impact on browser updates. In particular, this architecture has been implemented in Portasigma, which is Isigma's web application, and both technologies will doexist for a while to allow a gradual transition of the users.
