Which package needs to version 1.1?
libssl-dev or libcurl4-openssl-dev?

I have Ubuntu 16.04

How do I compile without SHA?

I thought the hash rate was pretty good for a 10w CPU.

I just enjoy playing, not any profit really.

libssl-dev 1.1 is needed but Ubuntu 16.04 has 1.0.2. None of the major distributions seem to have it yet.

How did you compile, did you change any options or just use the build script?
The option to add sha is "-msha" but the default compile probably includes it.
You might have to do something like ~~"-maes -mavx"~~ "-maes -msse4.2" instead
of the default "-march=native" to compile without sha.

Edit: correction, Goldmont doesn't have AVX.

I used the ./build.sh script to compile with HW SHA enabled and libssl-dev 1.0.2g-1ubuntu4.6 installed.

It is slower without the HW SHA.

That's a pretty big difference, big enough to convince me. Maybe SHA was back ported to some later 1.0 releases.
That's great if Ubuntu 16.04 etc have full support already.

Good work.

I used debian 9 with openssl 1.1 and got the same speed as ubuntu with the libssl-dev 1.0.2g-1ubuntu4.6 installed.
