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 could take as long as 120 days. Most space probes do not accelerate constantly, but use planetary gravity effects to speed up or slow down, which involves long, complex orbits taking a year or more. In this case, a spacecraft actually has to decelerate from the Earth's orbital speed (about 107,000 km/hr) to reach Venus or Mercury.
