It is named after the Italian explorer Christopher ...

Food historian Lois Ellen Frank calls potatoes, tomatoes, corn, beans, squash, chili, cacao, and vanilla the "magic eight" ingredients that were found and used only in the Americas before 1492 and ...
Key exchange. Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of ...

In an asymmetric key encryption scheme, anyone can encrypt messages using a public key, but only the holder of the paired private key can decrypt such a message.
