Cypher computer
A cipher is like a mathematical function, you input something and get an output. I input "ABC" into the cipher and it outputs "Hello There!". Code is more direct, you just look up what something means. A cipher is a way of translating the code without having everything listed out. WebEncryption is a form of data security in which information is converted to ciphertext. Only authorized people who have the key can decipher the code and access the original plaintext information. In even simpler terms, encryption is a way to render data unreadable to an unauthorized party. This serves to thwart cybercriminals, who may have used ...
