Hi Gerd, It will. But as Dmitrij already pointed out that there are Attribute Certificates. Those attributes are not part of the signed data, so they can be change (but also by anybody).
But inside a PKCS there are at least safe and for internal use, it might work. (But you do not want to send login information that maybe stored in a public certificate send to the outside world, so for my understanding, it will no longer be a public certificate, would it?) So long, --sk -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Freitag, 4.

If changing the arbitrary data does not invalidate the certificate, it must not be part of the digest, but then everybody would be able to change it. And just adding the arbitrary data to the PKCS12 file would not make those data more trustworthy either. If this is possible at all.
