Todd,
You could consider attaching the encrypted symmetric key to the encrypted log file as a custom extended attribute - if your server filesystem supports CAEs.

I'm hoping someone here might know the answer to this problem.
I have client computers encrypting log files and forwarding them to a server. I have a public key distributed to the clients, but the log files are too large to be encrypted with a public key. To address this, I
(1) generate a symmetric key on the fly
(2) encrypt the log file using symmetric encryption
(3) encrypt the symmetric key with the public key
(4) Send both the encrypted log file and encrypted symmetric key to the server
The problem is that now I need to track two files on the server. I would prefer that they were bundled together. Is there a standard way to combine these two into a single container file?
Thanks,
Todd
