Most of industrial or public domains involve a trusted and distributed infrastructure which provides individuals digital credentials and certificates. These latter allow their owner to authenticate herself, prove her rights and gain access inside trusted organizations. The certificate usability scope is extended to contain more and more information, where someones can be considered as sensitive. Contrary to existing certificate standards, we aim to provide a flexible format of certificate enabling to disclose, to blind and to cipher any authorized part of a certificate according to the user context, environment and willing. In this paper, we define and describe a new certificate model called: "X316" and we supply a security toolbox (i.e. X316 Signature, X316 Encryption and X316 Context) allowing its owner for managing her certificate freely according to contextual situation.
