.Sh NAME
|
|
.Nm ossl
|
|
.Nd "driver using OpenSSL assembly routines"
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device crypto"
|
|
.Cd "device cryptodev"
|
|
.Cd "device ossl"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
ossl_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The OpenSSL distribution includes architecture-specific
|
|
implementations for some commonly used cryptographic algorithms.
|
|
This driver adds a wrapper around these routines permitting them to be
|
|
used by in-kernel cryptography consumers such as kernel TLS and IPsec.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
