The cryptotest program repeatedly encrypts and decrypts a buffer
with the built-in iv and key, using hardware crypto. At the end,
it computes the data rate achieved. Operations are carried out by
making ioctl calls to /dev/crypto.
For a test of how fast a crypto card is, use something like:
cryptotest -z 1024
This will run a series of tests using the available crypto/cipher
algorithms over a variety of buffer sizes. The 1024 says to do
1024 iterations. Extra arguments can be used to specify one or
more buffer sizes to use in doing tests.
A sample run is:
0.129 sec, 2048 des crypts, 8 bytes, 127120 byte/sec, 1.0 Mb/sec
0.129 sec, 2048 des crypts, 16 bytes, 253915 byte/sec, 1.9 Mb/sec

Expect ~400 Mb/s for a Broadcom 582x for 16K buffers on a reasonable
CPU. Hifn 7811 parts top out at ~120 Mb/s. Performance depends
heavily on memory and bus performance.
This code originally came from openbsd; give them all the credit.
