 -evp val            Use EVP-named cipher or digest
 -decrypt            Time decryption instead of encryption (only EVP)
 -aead               Benchmark EVP-named AEAD cipher in TLS-like sequence
 -mb                 Enable (tls1>=1) multi-block mode on EVP-named cipher
 -mr                 Produce machine readable output
 -multi +int         Run benchmarks in parallel
 -async_jobs +int    Enable async mode and start specified number of jobs
 -rand val           Load the file(s) into the random number generator
 -writerand outfile  Write random data to the specified file
 -engine val         Use engine, possibly a hardware device
 -elapsed            Use wall-clock time instead of CPU user time as divisor
 -primes +int        Specify number of primes (for RSA only)
 -seconds +int       Run benchmarks for specified amount of seconds
