NAME

speed - test library performance

SYNOPSIS

openssl speed [-help] [-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

-help

Print out a usage message.

-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.
