NAME padlock — driver for the cryptographic functions and RNG in VIA C3, C7 and Eden processors SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configura‐ tion file: device crypto device padlock Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): padlock_load="YES" DESCRIPTION The C3 and Eden processor series from VIA include hardware acceleration for AES. The C7 series includes hardware acceleration for AES, SHA1, SHA256 and RSA. All of the above pro‐ cessor series include a hardware random number generator. The padlock driver registers itself to accelerate AES operations and, if available, HMAC/SHA1 and HMAC/SHA256 for crypto(4). It also registers itself to accelerate other HMAC algorithms, although there is no hardware acceleration for those algorithms. This is only needed so padlock can work with ipsec(4). The hardware random number generator supplies data for the kernel random(4) subsystem. SEE ALSO crypt(3), crypto(4), intro(4), ipsec(4), random(4), crypto(9) HISTORY The padlock driver first appeared in OpenBSD. The first FreeBSD release to include it was FreeBSD 6.0.BSD February 8, 2010 BSD
