Nils,

Sounds good. I'm also doubtful of depending on two crypto libraries when
OpenSSL does perfectly well.

However, losing compatibility with miners is not very nice. Is there really
not a way to compute midstate with OpenSSL?

Hey,<br>
<br>
I&#39;d like to simplify the internal reference miner and remove all<br>

Any thoughts? Where should such a change should be announced so all<br>
miners can be upgraded?<br>
