cryptsetup-benchmark - benchmarks ciphers and KDF
|
|
|
|
== SYNOPSIS
|
|
|
|
*cryptsetup _benchmark_ [<options>]*
|
|
|
|
== DESCRIPTION
|
|
|
|
Benchmarks ciphers and KDF (key derivation function). Without
|
|
parameters, it tries to measure few common configurations.
|
|
|
|
To benchmark other ciphers or modes, you need to specify *--cipher* and
|
|
*--key-size* options.
|
|
|
|
To benchmark PBKDF you need to specify *--pbkdf* or *--hash* with optional
|
|
cost parameters *--iter-time*, *--pbkdf-memory* or *--pbkdf-parallel*.
|
|
|
|
*NOTE:* This benchmark uses memory only and is only informative. You
|
|
cannot directly predict real storage encryption speed from it.
|
|
|
|
For testing block ciphers, this benchmark requires kernel userspace
|
|
crypto API to be available (introduced in Linux kernel 2.6.38). If you
|
|
are configuring kernel yourself, enable "User-space interface for
|
|
symmetric key cipher algorithms" in "Cryptographic API" section
|
|
(CRYPTO_USER_API_SKCIPHER .config option).
|
|
|
|
*<options>* can be [--cipher, --key-size, --hash, --pbkdf, --iter-time,
|
|
--pbkdf-memory, --pbkdf-parallel].
