These benchmarks provide a rough estimate of how OpenSSL performance varies on various hardware and software configurations.

1. Install openssl-utils (with its depencies this will require about 790KiB of storage)

   opkg install openssl-util

2. Simply drop the following line into the shell:

   openssl speed md5 sha1 sha256 sha512 des des-ede3 aes-128-cbc aes-192-cbc aes-256-cbc rsa2048 dsa2048 | tee /tmp/sslspeed | awk -v ORS="" '$1 ~ /OpenSSL/ {print "| " $2 " |"} $1 ~ /(md5|sha)/ {print "  " $5 " |"} $1 ~ /(des|aes)/ {b = b "  " $6 " |"} $1 ~ /(rsa|dsa)/ {print b "  " $6 " |  " $7 " |";b=""} END { print "\n" }' | sed 's/\.\(..\)k/\10/g'

3. copy-paste the result into this wiki-page
4. Afterwards you can remove the package and it's dependencies (if not needed by other packages) again with:

   opkg remove openssl-util libopenssl zlib

just one Core is used

You have to compile libopenssl with hardware acceleration if your hardware support it to get better score:

make menuconfig
Libraries -> 
SSL -> 
libopenssl: m
Configuration ->
Crypto acceleration support: y

Also you can read more about cryptographic hardware accelerators.

Instead of copying the output by hand you can drop this sausage into the CLI:

cat /etc/banner | awk '/\(/ {print $2 " " $3 " " $4}'
cat /proc/cpuinfo | awk '/system type/ {FS = ":" ; print "|" $2}; /machine/ {FS = ":" ; print $2}; /cpu model/ {FS = ":" ; print $2}; /BogoMIPS/ {FS = ":" ; print $2 " |"}' | sed ':M;N;$!bM;s#\n# |#g'
openssl speed md5 sha1 sha256 sha512 des des-ede3 aes-128-cbc aes-192-cbc aes-256-cbc rsa2048 dsa2048 | tee /tmp/sslspeed | awk -v ORS="" '$1 ~ /OpenSSL/ {print "| " $2 " |"} $1 ~ /(md5|sha)/ {print "  " $5 " |"} $1 ~ /(des|aes)/ {b = b "  " $6 " |"} $1 ~ /(rsa|dsa)/ {print b "  " $6 " |  " $7 " |";b=""} END { print "\n" }' | sed 's/\.\(..\)k/\10/g'

The following code saves /tmp/sslspeed while showing progress, then output a table to check if the sort is correct, then use last command line output to copy & paste.

• Benchmarks are based on running:

cat /proc/cpuinfo
cat /proc/crypto
openssl speed md5 sha1 sha256 sha512 des des-ede3 aes-128-cbc aes-192-cbc aes-256-cbc rsa2048 dsa2048

• Please include the output for 1024 byte blocks only!
• Hash and block ciphers use 1024 byte blocks; "k" refers to 1000 bytes per second, so the "k" is removed and result multiplied x1000.
• Certificate verification and signing are based on 2048 bit keys; the values are the number of signings/verifications per second.
