WebJul 6, 2024 · The purpose of steganography is to conceal and deceive. It is a form of covert communication and can involve the use of any medium to hide messages. It’s not a form of cryptography, because it doesn’t involve scrambling data or using a key. Instead, it is a form of data hiding and can be executed in clever ways. WebPurpose [ edit] Since the key protects the confidentiality and integrity of the system, it is important to be kept secret from unauthorized parties. With public key cryptography, only the private key must be kept secret , but with symmetric cryptography, it is important to maintain the confidentiality of the key.
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.
Webasymmetric cryptography (public key cryptography): Asymmetric cryptography , also known as public key cryptography, uses public and private keys to encrypt and decrypt data.
