NAME
       speed - test library performance

SYNOPSIS
       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]

DESCRIPTION
       This command is used to test the performance of cryptographic algorithms.

OPTIONS
       -engine id
	   specifying an engine (by its 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.

       [zero or more test algorithms]
	   If any options are given, speed tests those algorithms, otherwise all of the above are tested.
