Re: bandwidth loss using cryptography

Hi .. I think your question should be in regards of the performance of a device when using encryption for example a PIX 501E provides

■ Maximum clear-text throughput—60 Mbps

■ Maximum throughput (DES)—6 Mbps

■ Maximum throughput (AES-128)—4.5 Mbps

■ Maximum throughput (3DES)—3 Mbps

As you can see it depends of the device you are using and also of the encryption algorithm.

PLease rate it if you find this info helpfull
