A Discussion on Zen Buddhism and Cryptography

2025-09-15 by boardor

It is well known that the stability of the world’s financial infrastructure relies on the RSA encryption algorithm used by banks. This algorithm ultimately hinges on the difficulty of prime factorization. Since factorizing large numbers is a challenging task, almost impossible to accomplish manually, even computers would take thousands of years to crack a large … Read more

An Overview of Cryptographic Encryption Algorithms

2025-09-15 by boardor

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
