At its core, cryptography ensures that data remains confidential, authentic, and tamper-proof, even when transmitted over insecure channels such as the internet. It plays a crucial role in safeguarding privacy, integrity, and trust in digital communication and data storage. it involves various techniques such as symmetric-key cryptography, asymmetric-key cryptography, and cryptographic hash functions.
Symmetric-Key Cryptography: This method uses the same secret key for both encryption and decryption. It is fast and efficient for large datasets but requires secure key distribution, as both the sender and the receiver must have access to the same key. Popular examples include the Advanced Encryption Standard (AES) and the Data Encryption Standard (DES).
Asymmetric-Key Cryptography: Also known as public-key cryptography, this method uses a pair of keys: a public key for encryption and a private key for decryption. The most widely used asymmetric cryptography system is the RSA algorithm. Asymmetric cryptography simplifies key management and enables secure communication without needing to share a secret key in advance.
Cryptographic Hash Functions: These are used to ensure data integrity. A hash function takes an input and generates a fixed-size string, typically represented as a “digest.” Even a small change in the input will produce a vastly different hash. Hash functions are fundamental in digital signatures, password storage, and blockchain technology.
