In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot.
I have a client who is considering encryption options in order to comply with a tendering requirement.
Were they to encrypt the production database then what would be a reasonable expectation forthe impact on message throughput. Or possibly more easily answered: what would be the expected impact be on I/O rate and CPU utilization. Are there any benchmarks to which could support an estimate ?
How would this compare with plan B: to use disk encryption ?
