I tested this software, got about 10 Megahashes/second with mobile quad core CPU. Of course that is not much if you compare to GPUs,
but if you have high-performance server at your disposal - with a lot of server-class CPUs - that command line software could help you a lot

Make a brief look at README file before using. If you would get htobe32 compilation error, open eschalot.c file and uncomment "#define NEED_HTOBE32"

Not all, my friend

As result of NSA espionage all over USA, there is a large trend - to move the servers from USA to offshore locations:

Companies/individuals, who value their privacy (such as BitCoin users) would prefer good privacy
than a few percent higher uptime - although, it is very nice when you could afford getting both!  

If you research the subject, USA networking industry is losing lots of untold money, as result of NSA actions
(according to estimates, that are two-digit billion dollar figures) - so, it does not look wise to enter this market.
Meanwhile, there are only a few Indian-based web hostings that accept Bitcoin, not much competition here...

Dear friend, of course I am not in position to tell you what to do - but, in my humble opinion,
your business would be more successful if you would be operating at India. Luckily, the Indian infrastructure
is developing rapidly, and since most Bitcoin users are tech-savvy, the need in super tech support is not that urgent.
In addition, you would be able to clearly state that your Indian servers are not affected by NSA operations,
which would differentiate you from competitors, and raise confidence among your potentional customers

It took me a lot of time to find a copy of Eschalot, so I am sharing it here in hope that it would fulfill someone's needs.
Note: I am sharing it AS-IS. If you suspect that the code was modified by uploader, then use it inside Virtual Machine

Since the only Indian thing about this company is a physical location of business holder (administration),
while all the assets (servers, communication lines, customer support, etc) that are used for conducting business, are in U.S.,
it is misleading to label this company as simply Indian. His announcement should have been posted to U.S. section of forum

I totally understand your point, about superior quality of service in US. But, there is a problem:

Most people who are using BitCoin, do care about privacy - and there is no true privacy with US/Europe-based web hostings

After all these revelations about NSA mass surveillance programs,
I doubt that Bitcoin users would want a server in NSA-plagued country

-----

Privacy is more important issue than 2%-5% difference in uptime.
If you would have offered true India-based server with Bitcoin payment,
it will surely find its customer - not only thanks to higher privacy,
but also because Indian servers are usually cheaper!

Well, I thought that you are Indian web hosting company, as you have stated.
I seriously considered ordering 1 year web hosting from you, until I discovered that:

Hosticon.com - 192.185.155.106 - United states


That makes you USA web hosting company, not Indian. Stop misleading your customers!
And I have no desire to have web hosting with servers in USA - because of NSA espionage :

Unless you don't care about privacy of the visitors of your website, please stay away from USA/European web hostings
