see \*(L"\s-1COMMAND SUMMARY\*(R"\s0 in \fIopenssl\fR\|(1).
|
|
.IP "\fB\-elapsed\fR" 4
|
|
.IX Item "-elapsed"
|
|
When calculating operations\- or bytes-per-second, use wall-clock time
|
|
instead of \s-1CPU\s0 user time as divisor. It can be useful when testing speed
|
|
of hardware engines.
|
|
.IP "\fB\-evp\fR \fIalgo\fR" 4
|
|
.IX Item "-evp algo"
|
|
Use the specified cipher or message digest algorithm via the \s-1EVP\s0 interface.
|
|
If \fIalgo\fR is an \s-1AEAD\s0 cipher, then you can pass \fB\-aead\fR to benchmark a
|
|
TLS-like sequence. And if \fIalgo\fR is a multi-buffer capable cipher, e.g.
|
|
aes\-128\-cbc\-hmac\-sha1, then \fB\-mb\fR will time multi-buffer operation.

Time the \s-1HMAC\s0 algorithm using the specified message digest.
|
|
.IP "\fB\-cmac\fR \fIcipher\fR" 4

Time the decryption instead of encryption. Affects only the \s-1EVP\s0 testing.

|
|
Benchmark signature algorithms: key generation, signature, verification.
|
|
.IP "\fB\-primes\fR \fInum\fR" 4
|
|
.IX Item "-primes num"
|
|
Generate a \fInum\fR\-prime \s-1RSA\s0 key and use it to run the benchmarks. This option
|
|
is only effective if \s-1RSA\s0 algorithm is specified to test.
|
|
.IP "\fB\-seconds\fR \fInum\fR" 4

.IX Item "-bytes num"
|

Run benchmarks on \fInum\fR\-byte buffers. Affects ciphers, digests and the \s-1CSPRNG.\s0
|

The limit on the size of the buffer is \s-1INT_MAX \- 64\s0 bytes, which for a 32\-bit
