Subject: Getting started with crypto drivers
Date: Sun, 29 Sep 2013 15:10:27 -0300	[thread overview]
Message-ID: <52486D13.1000800@elopez.com.ar> (raw)

Hello everyone,

I would like to write a driver to support the "Security System" hardware 
block on some Allwinner ARM SoCs. The hardware supports AES, DES, 3DES, 
SHA-1, MD5 and has a PRNG. Data passing is done via two FIFOs. You can 
find some ugly userspace code to calculate a SHA1 hash here, so you can 
get an idea of how it works:

http://git.elopez.com.ar/ss-poc/raw/31c57d893ce8913aa0d87c982f5350433fbe89c7/md5-tool.c

My main issue at the moment is that I do not have any experience working 
with the crypto API, and that I found the documentation on 
Documentation/ lacking for my purposes. I'd be very grateful if you 
could suggest me reading material to understand the "hardware-oriented" 
API better, and if you could point me to good drivers I could use as an 
example when developing my own.

Thanks!

Emilio
