Re: [openssl-dev] Speck Cipher Integration with OpenSSL

Hi Dmitry, We implemented it using the same means as we saw the other ciphers. It was using the EVP functions. This way it could be included or excluded via makefile. Regards, Bill On 1/9/2018 12:23 AM, Dmitry Belyavsky wrote: Dear William, Does SPECK implementation need to be a part of t

I don’t think anyone is talking about OpenSSL depending on or requiring Apache; that’s a non-starter. It would be interesting to see how many changes you need to support your platform. -- openssl-dev mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-dev

Dear William, Does SPECK implementation need to be a part of the OpenSSL bundle itself? It can be added as engine, similar to Russian GOST support, with minimal patches providing OIDs/NIDs if necessary. On Fri, Jan 5, 2018 at 9:52 PM, William Bathurst wrote: > Hello All, > > We have open source
