3The cryptotest program repeatedly encrypts and decrypts a buffer
4with the built-in iv and key, using hardware crypto. At the end,
5it computes the data rate achieved. Operations are carried out by
6making ioctl calls to /dev/crypto.

8For a test of how fast a crypto card is, use something like:
9
10 cryptotest -z 1024
11
12This will run a series of tests using the available crypto/cipher
13algorithms over a variety of buffer sizes. The 1024 says to do
141024 iterations. Extra arguments can be used to specify one or
15more buffer sizes to use in doing tests.

40Expect ~400 Mb/s for a Broadcom 582x for 16K buffers on a reasonable
41CPU. Hifn 7811 parts top out at ~120 Mb/s. Performance depends
42heavily on memory and bus performance.
