1 2The cryptotest program repeatedly encrypts and decrypts a buffer 3with the built-in iv and key, using hardware crypto. At the end, 4it computes the data rate achieved. Operations are carried out by 5making ioctl calls to /dev/crypto. 6 7For a test of how fast a crypto card is, use something like: 8 9 cryptotest -z 1024 10 11This will run a series of tests using the available crypto/cipher 12algorithms over a variety of buffer sizes. The 1024 says to do 131024 iterations. Extra arguments can be used to specify one or 14more buffer sizes to use in doing tests. 15 16A sample run is: 17 18 0.129 sec, 2048 des crypts, 8 bytes, 127120 byte/sec, 1.0 Mb/sec 19 0.129 sec, 2048 des crypts, 16 bytes, 253915 byte/sec, 1.9 Mb/sec 20 0.129 sec, 2048 des crypts, 32 bytes, 508942 byte/sec, 3.9 Mb/sec 21 0.128 sec, 2048 des crypts, 64 bytes, 1020135 byte/sec, 7.8 Mb/sec 22 0.134 sec, 2048 des crypts, 128 bytes, 1954869 byte/sec, 14.9 Mb/sec 23 0.142 sec, 2048 des crypts, 256 bytes, 3698107 byte/sec, 28.2 Mb/sec 24 0.190 sec, 2048 des crypts, 1024 bytes, 11037700 byte/sec, 84.2 Mb/sec 25 0.264 sec, 2048 des crypts, 2048 bytes, 15891127 byte/sec, 121.2 Mb/sec 26 0.403 sec, 2048 des crypts, 4096 bytes, 20828998 byte/sec, 158.9 Mb/sec 27 0.687 sec, 2048 des crypts, 8192 bytes, 24426602 byte/sec, 186.4 Mb/sec 28 0.129 sec, 2048 3des crypts, 8 bytes, 127321 byte/sec, 1.0 Mb/sec 29 0.131 sec, 2048 3des crypts, 16 bytes, 249773 byte/sec, 1.9 Mb/sec 30 0.128 sec, 2048 3des crypts, 32 bytes, 512304 byte/sec, 3.9 Mb/sec 31 0.128 sec, 2048 3des crypts, 64 bytes, 1021685 byte/sec, 7.8 Mb/sec 32 0.132 sec, 2048 3des crypts, 128 bytes, 1986511 byte/sec, 15.2 Mb/sec 33 0.142 sec, 2048 3des crypts, 256 bytes, 3695005 byte/sec, 28.2 Mb/sec 34 0.190 sec, 2048 3des crypts, 1024 bytes, 11024876 byte/sec, 84.1 Mb/sec 35 0.264 sec, 2048 3des crypts, 2048 bytes, 15887997 byte/sec, 121.2 Mb/sec 36 0.402 sec, 2048 3des crypts, 4096 bytes, 20850846 byte/sec, 159.1 Mb/sec 37 0.689 sec, 2048 3des crypts, 8192 bytes, 24333532 byte/sec, 185.7 Mb/sec 38 39Expect ~400 Mb/s for a Broadcom 582x for 16K buffers on a reasonable 40CPU. Hifn 7811 parts top out at ~120 Mb/s. Performance depends 41heavily on memory and bus performance. 42 43This code originally came from openbsd; give them all the credit. 44
