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].
