Subject Re: splittable encrypted compressed files

A encryption/decryption mechanism requires the secret key to be
securely distributed. As far as moving data on the wire is concerned,
SSH is already being used. I am wondering about the performance hit
when encryption and then again decryption is applied to the data and
what value that might add.
