Encryption+Compression [7:7012]
Hello, Is it good to both compress and encrypt data going out of an interface?

Compression, if performed *before* encrypting, removes redundancy, thus making cryptanalysis much harder. It used to be, though, that cisco routers, when asked to do both, would insist on encrypting first, thus essentially turning compression into a time-consuming no-op. I haven't looked whether that was still the case. Hmm... *browse* *browse* *ping* *traceroute* Sorry, can't get to CCO. -- "Someone approached me and asked me to teach a javascript course.

It is known as IPPCP, compression before encryption. It can be done in software but none of the Encryption hardware accelerators support it. Look at the comp-lzs Transform.
