WebCryptography is as old as human communication itself, but has undergone a revolution in the last few decades. It is now about much more than secret writing and includes seemingly paradoxical notions such as communicating securely without a shared secret and computing on encrypted data. WebJun 20, 2024 · 3) Simple operations. Visual Cryptography is a special encryption technique to hide information in images in such a way that it can be decrypted by the human vision if the correct key image is used. Visual Cryptography uses two transparent images. One image contains random pixels and the other image contains the secret information.

Cryptography, or cryptology (from Ancient Greek: κρυπτός, romanized: kryptós "hidden, secret"; and γράφειν graphein, "to write", or -λογία -logia, "study", respectively ), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public fro…
WebAn encryption algorithm is a mathematical formula used to transform plaintext (data) into ciphertext. An algorithm will use the key to alter the data in a predictable way. Even though the encrypted data appears to be random, it can actually be turned back into plaintext by using the key again.
