 Cryptographic algorithms

Cryptographic algorithms are mathematical procedures used to perform encryption and decryption, ensuring the confidentiality, integrity, authentication, and non-repudiation of information. These algorithms transform data into a format that is unreadable to unauthorized users while allowing authorized users to access the original data using a specific key. Cryptographic algorithms can be classified into several categories: 1. **Symmetric Key Algorithms**: In these algorithms, the same key is used for both encryption and decryption.
