Home | Tasks | Protect a Password Database with a One-way Hash Protect a Password Database with a One-way Hash A one-way hash function is a cryptographic algorithm that turns an arbitrary-length input into a fixed-length binary value, and this transformation is one-way, that is, given a hash value it is statistically infeasible to re-create a document that would produce this value.
The number of times the ISS (International Space Station) orbits the Earth each day - or once every 90 minutes. That's a lot of sunsets and sunrises! Sunsets to view are getting few...goodnight Earth pic.twitter.com/FQpIbDbdD3.
It varies according to the height of the orbit. The ISS though is orbiting at about 17,000 mph which would indicate that one complete orbit would take about 90min. You can check on visibility timings of various satellites at two very good websites, www.heavens-above.com or www.calsky.com.
