The license on the 2 asm files from openssl the explicitly states: @ ==================================================================== @ Written by Andy Polyakov for the OpenSSL @ project. The module is, however, dual licensed under OpenSSL and @ CRYPTOGAMS licenses depending on where you obtain it. For further @ details see http://www.openssl.org/~appro/cryptogams/. @ ==================================================================== If you follow the URL for the CRYPTOGAMS license and read the actual license at the end of the file it is very clearly dual licensed. So I think it is ok :-) 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.
