WebMar 16, 2024 · 2. Trapdoors. In cryptography, a trapdoor is a secret backdoor hidden within an algorithm or individual piece of data. The idea is that people can’t find the backdoor without knowing about it in advance. It makes trapdoors extremely useful in cryptography, which keeps information secure by converting it into unbreakable codes. It was the formation of the first computer networks that started civilians thinking about the importance of cryptography. Computers were talking to each other over the open network, not just via direct connections to one another; that sort of networking was transformative in many great ways, but also made it trivially … See more Cryptography is the art of keeping information secure by transforming it into form that unintended recipients cannot understand.

Webcipher: A cipher (pronounced SAI-fuhr ) is any method of encrypting text (concealing its readability and meaning). It is also sometimes used to refer to the encrypted text message itself although here the term ciphertext is preferred. Its origin is the Arabic sifr , meaning empty or zero . In addition to the cryptographic meaning, cipher also ...
