WebApr 21, 2024 · Cryptography provides methods for secure communication and electronic data that malicious adversaries cannot read, interpret, or access. What is cryptography? Cryptography is used to keep messages and data secure from being accessible to anyone other than the sender and the intended recipient. WebCryptographic techniques include encryption, which involves applying a procedure called an algorithm to plain text to turn it into something that will appear to be gibberish to anyone who doesn’t have the key to decrypt it. Encryption is a form of cryptography that “scrambles” plain text into unintelligible cipher text. Encryption is the foundation of such security …
