S/MIME implementation that uses authenticated-data?

[Bernhard Reiter]

Hi,
do you know any S/MIME (or CMS) implementations that
use authenticated-data type from STD 70 aka RFC 5652?

If we wanted to implement this for GnuPG's gpgsm,
it would be very cool to have implementations to test against.

The ticket is https://dev.gnupg.org/T3979, you can also reply there.

Thanks,
Bernhard
