30.Sh NAME
31.Nm padlock
32.Nd "driver for the cryptographic functions and RNG in VIA C3, C7 and Eden processors"
33.Sh SYNOPSIS
--- 14 unchanged lines hidden (view full) ---
48.Sh DESCRIPTION
49The C3 and Eden processor series from VIA include hardware acceleration for
50AES.
51The C7 series includes hardware acceleration for AES, SHA1, SHA256 and RSA.
52All of the above processor series include a hardware random number generator.
53.Pp
54The
55.Nm
56driver registers itself to accelerate AES operations and if available HMAC/SHA1
57and HMAC/SHA256 for
58.Xr crypto 4 .
59It also registers itself to accelerate other HMAC algorithms, although
60there is no hardware acceleration for those algorithms.
61This is only needed, so
62.Nm
63can work with
64.Xr fast_ipsec 4 .
65.Pp
66The hardware random number generator supplies data for the kernel
67.Xr random 4
68subsystem.
69.Sh HISTORY
70The
71.Nm
72driver first appeared in
73.Ox .
74The first
75.Fx
76release to include it was
77.Fx 6.0 .

87The
88.Nm
89driver with AES encrytion support was written by
90.An Jason Wright Aq jason@OpenBSD.org .
91It was ported to
92.Fx
93and then extended to support SHA1 and SHA256
