WebIn data and telecommunications, cryptography is necessary when communicating over any untrusted medium, which includes just about any network, particularly the Internet. Cryptography is a method of protecting information and communications through the use of codes, so that only those for whom the information is intended can read and process it. WebMay 20, 2024 · Cryptography refers to the creation of a secure means of communication through use of an algorithm and a decryption key. In most cases, that involves scrambling text until it is unreadable, while still being able to reverse that process if you or someone you trust needs to see it.
