Hello all

i have a question. An application want to access an ecryptfs protected file; 
then Ecryptfs retrieves the metadata bound to the file and decrypts the FEK 
using a matched key in the user  keyring; finally Ecryptfs setup a 
cryptographic context and the inode for the requested file becomes active. The 
file can be read from all applications that have permission using the same 
cryptographic context, if i'm not wrong. There's a way to block at this point 
the decryption using for example a per-application policy?
Is this the better point where it's possible to insert a "policy manager", 
eventually modifying the original code?

Thanks
