This document discusses cyber or online contracts. It defines a cyber-contract as one created through communications over computer networks, whether entirely through email exchanges showing offer and acceptance, or a combination of electronic and other means. The key elements of a valid contract - offer, acceptance, consideration, and consent - still apply to online contracts. Digital signatures can verify the identity of parties to an online contract by encrypting messages with public and private keys. This allows confirmation that a message has not been altered and verifies the sender. Overall, the document outlines how traditional contract law elements can be applied to agreements made electronically.
