If you find this article beneficial, feel free to share it. In this digital age, every online transaction and every encrypted email relies on a sophisticated encryption system. Today, I want to talk about the RSA algorithm (Rivest-Shamir-Adleman, named after its three inventors), the foundation of public key encryption that builds a security barrier in … Read more
This article introduces commonly used cryptographic algorithms in daily development. abstract.png Classical Cryptography Classical cryptography typically employs simple techniques such as substitution (replacing letters in plaintext with other letters) and transposition (rearranging the order of letters in plaintext), without the need for complex machines or algorithms. Therefore, its security is insufficient and easily compromised. Caesar … Read more
1. Definition of Asymmetric Encryption Algorithms An asymmetric encryption algorithm is a type of encryption technology that uses a pair of keys for encryption and decryption. Unlike symmetric encryption, asymmetric encryption uses two keys: a public key for encrypting data and a private key for decrypting it. Only the recipient who possesses the private key … Read more
