• The idea of RSA is based on the fact that it is difficult to factorize a large integer. The public key consists of two numbers where one number is multiplication of two large prime numbers. And private key is also derived from the same two prime numbers. So if somebody can factorize the large number, the private key is compromised. Therefore encryption strength totally lies on the key size and if we double or triple the key size, the strength of encryption increases exponentially.

• Example 1 - Using own RSA implementation in ABAP. RSA encryption is quite simple. All you need is integer arithmetic - mainly modular exponentiation. The only problem is, the integers involved are longer than ABAP and most other languages can handle by default. Luckily this problem is solved by Harry Boeck with the class Z04_BIGINTX which can be found here (excellent work). Generating the RSA key

Here you will learn about RSA algorithm in C and C++. RSA Algorithm is used to encrypt and decrypt data in modern computer systems and other electronic devices. RSA algorithm is an asymmetric cryptographic algorithm as it creates 2 different keys for the purpose of encryption and decryption. It is public key cryptography as one of the keys involved is made public. RSA stands for Ron Rivest, Adi Shamir and Leonard Adleman who first publicly described it in 1978 However, RSA is almost never used by its own. Usually encryption is performed using random key and symmetric algorithm, and then the random key is encrypted with RSA. So if you want data encryption and decide to write your own stuff, you will be reinventing the wheel Part A - RSA Encryption ''' import random ''' Euclid's algorithm for determining the greatest common divisor: Use iteration to make it faster for larger integers ''' def gcd (a, b): while b!= 0: a, b = b, a % b: return a ''' Euclid's extended algorithm for finding the multiplicative inverse of two numbers ''' def multiplicative_inverse (e, phi): d = 0: x1 = 0: x2 = 1: y1 = 1: temp_phi = ph Most of the implementations of RSA will accept exponents generated using either method (if they use the private exponent d at all, rather than using the optimized decryption method based on the Chinese remainder theorem described below), but some standards such as FIPS 186-4 may require that d < λ(n) ### RSA implementation from your own using GU

This is also called public key cryptography, because one of the keys can be given to anyone Instead, we'll be using the RSA base class, which will return a platform-specific RSA implementation: On Windows: an RSA object implemented from CNG (Crypto API: Next Generation). On Linux and MacOS: an RSA object implemented from OpenSSL. So we're going to need something that will hand us back an RSA object. Let's add a private method to do so. We'll be using our configuration object to set.

Each RSA implementation relies on other cryptographic primitives. For example, RSA keyGen often uses an underlying SHA algorithm. Each of these underlying algorithm primitives must be validated, either separately or as part of the same submission. ACVP provides a mechanism for specifying the required prerequisites:� RSA is a well‐known public key cryptosystem providing resistance to cryptanalytic attacks.However, RSA implementations are at risk from side channel attacks. RSAimplementation is divided into two methods: RSA‐base and RSA‐CRT. RSA‐base isused for both digital signature and signature verification, while RSA‐CRT isused for digital signature only. In this paper, our focus is on RSA. Most RSA implementations use an optimization called the Chinese Remainder Theorem or CRT. With CRT, the implementation performs the exponentiation m e mod n as two separate operations, m e mod p and m e mod q. The two parts are combined at the end. Since p and q are about half the size of n (which is p * q), this speeds up the exponentiation a lot because the multi-word numbers are smaller. In earlier JDK releases, there were no RSA signature providers available in the JDK, therefore SunJSSE had to provide its own RSA implementation in order to use commonly available RSA-based certificates
