speed - test library performance
openssl speed [-engine id] [md2] [mdc2] [md5] [hmac] [sha1] [rmd160] [idea-cbc] [rc2-cbc] [rc5-cbc] [bf-cbc] [des-cbc] [des-ede3] [rc4] [rsa512] [rsa1024] [rsa2048] [rsa4096] [dsa512] [dsa1024] [dsa2048] [idea] [rc2] [des] [rsa] [blowfish]
This command is used to test the performance of cryptographic algorithms.
specifying an engine (by it's unique id string) will cause speed to attempt to obtain a functional reference to the specified engine, thus initialising it if needed. The engine will then be set as the default for all available algorithms.
If any options are given, speed tests those algorithms, otherwise all of the above are tested.
