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.
Despite being relatively close, the ISS is traveling at more than 17,000 miles per hour in a circular orbit around Earth. Anything moving that fast, whether in space or on the ground, is going to be hard to catch. As it turns out, the way you catch the ISS is counterintuitive: You actually let it catch you.
