Cryptography, RSA, and hashing. Learn to harden systems, explore VMs, and unlock classic ciphers. Dive into the math behind RSA public-key encryption and secure passwords with modern hashing, salting, and algorithms like Bcrypt. This bundle covers the core concepts you need to succeed.

This comprehensive study guide offers a complete breakdown of Hashing, starting with simple error-checking methods and progressing to the complex cryptographic functions that secure our digital world. The notes begin with the fundamentals, using parity checking as a basic example of error detection before defining a hash function as a computable function that maps an input of any size to a fixed-size output. A key concept explored is that of hash collisions and the famous "Birthday Problem,...

This comprehensive guide is structured to build your knowledge step-by-step. 1. Introduction to RSA Public Key Cryptography Start with the core principles of asymmetric encryption and the geniuses behind the algorithm. - The RSA Algorithm: Named after its creators—Rivest, Shamir, and Adleman. - Public and Private Keys: Learn how RSA uses a public key (K) that is freely available and a private key (G) that is hidden. - One-Way Functions: Grasp the fundamental concept that makes RSA secur...
