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.
2 Answers 2. The ISS orbit is prograde - in the direction of the Earth rotation. Prograde orbits are orbits with inclination less than 90 degrees. ISS inclination is 51.6 degrees. These orbits are slightly easier to reach, because they don't require as much fuel, as you get additional kick from the Earth during launch.
