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]. + +include::man/common_options.adoc[] +include::man/common_footer.adoc[] |
