SPEED(1)                            OpenSSL                           SPEED(1)

NAME
       speed - test library performance
SYNOPSIS
       openssl speed [-engine id] [-elapsed] [-evp algo] [-decrypt] [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.
       -elapsed
           Measure time in real time instead of CPU time. It can be useful
           when testing speed of hardware engines.
       -evp algo
           Use the specified cipher or message digest algorithm via the EVP
           interface.
       -decrypt
           Time the decryption instead of encryption. Affects only the EVP
           testing.
       [zero or more test algorithms]
           If any options are given, speed tests those algorithms, otherwise
           all of the above are tested.
