[Freeipa-devel] GSS-Proxy <-> TPM <-> PKCS#11 (silly idea)

[Petr Spacek]

Hello,

I have got an silly idea to use TPM (Trusted Platform Module) as backend for 
Keytab storage (via GSS-Proxy).

GSS-Proxy prevents application from accessing key material, right? So 
GSS-Proxy could theoretically store keys in TPM and application wouldn't 
notice any difference, right?

We have libraries for that in Fedora already:
https://admin.fedoraproject.org/pkgdb/acls/name/trousers


Even sillier idea is to use TPM as a PKCS#11 module:
http://trousers.sourceforge.net/pkcs11.html

I have no idea what the use case could be ... :-) May be as a "cache" for 
PKCS#11 module in SSSD?


As I said, it is just a silly idea.
