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.
How fast does the Space Station travel? The International Space Station travels in orbit around Earth at a speed of roughly 17,150 miles per hour (that's about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes! You can see the ISS' location and speed at this link which also has a real-time video feed from cameras attached to the outside of the station. Cool Cosmos is an IPAC website.
