![]() ![]() Kerckhoff's principle states that the entire security of the cryptographic system relies on the secrecy of the key. 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. ![]() Since the key protects the confidentiality and integrity of the system, it is important to be kept secret from unauthorized parties. These keys are known as the public and private keys, respectively. Asymmetric cryptography Īsymmetric cryptography has separate keys for encrypting and decrypting. Symmetric cryptography refers to the practice of the same key being used for both encryption and decryption. ![]() There are different methods for utilizing keys and encryption. The key is what is used to encrypt data from plaintext to ciphertext. A key’s security strength is dependent on its algorithm, the size of the key, the generation of the key, and the process of key exchange. Based on the used method, the key can be different sizes and varieties, but in all cases, the strength of the encryption relies on the security of the key being maintained. ![]() A key in cryptography is a piece of information, usually a string of numbers or letters that are stored in a file, which, when processed through a cryptographic algorithm, can encode or decode cryptographic data. ![]()
