The AOC Consortium works continuously to obtain the maximum recognition of its certificates as well as to guarantee their operation with the most used combinations of operating systems and computer programs (Internet browsers, office applications, etc.).
In the same sense, the analysis of the profiles of the users of the AOC Consortium certificates has made it possible to identify which of these combinations are most used and to concentrate efforts on maintaining the compatibility of the AOC Consortium certificates with them.
The following tables show the different compatibility scenarios of the AOC Consortium certificates.
