So I think it is > ok :-) The FAQ at http://www.openssl.org/~appro/cryptogams/ says "If obtained as a part of the OpenSSL Toolkit the modules are covered by the OpenSSL license, while if obtained as a part of the CRYPTOGAMS distribution - by the CRYPTOGAMS License" and that page only has link to "CRYPTOGAMS version 0" which does not contain ARM implementations. -Jussi > > Cheers, > Davidm > > > -----Original Message----- > > From: linux-crypto-owner@vger.kernel.org > > [mailto:linux-crypto-owner@vger.kernel.org] On Behalf Of Herbert Xu > > Sent: Thursday, September 06, 2012 10:20 PM > > To: David McCullough > > Cc: linux-kernel@vger.kernel.org; linux-crypto@vger.kernel.org > > Subject: Re: [PATCH 1/1] arm/crypto: Add optimized AES and SHA1 routines > > > > On Tue, Aug 07, 2012 at 02:01:03AM +0000, David McCullough wrote: > > > > > > Add assembler versions of AES and SHA1 for ARM platforms.
