The texts justify the decryption process by saying the private key is the multiplicative inverse of the public key therefore it nullifies the encryption the Public key does. However, the private key is calculated with modulo phi(n), while the encryption/decryption is done over modulo n. The Python and NumPy indexing operators [] and attribute operator . provide quick and easy access to pandas data structures across a wide range of use cases. This makes interactive work intuitive, as there's little new to learn if you already know how to deal with Python dictionaries and NumPy arrays. - Letter to employees regarding health insurance

Modular inverse of Bitcoin keys - Where, Why, How & WARNING It really goes without. Over the last some age, the idea of cryptocurrencies has exploded, and more mass than ever mortal invested Hoosier State currencies look-alike Bitcoin. Here's my implementation in Matlab: function xInv = modInv(x,n) % ModInv(x,n) computes the multiplicative inverse of x modulo n if one. % exists; errors if no such inverse exists. if gcd(x,n) ~= 1. error('x has no inverse modulo n') end. [d, a, b] = gcd(x,n); xInv = mod(a,n); In order to receive the inverse number, one should perform the following transformations: a·x + b·y = 1 b·y = 1 (in Z a) Thus, b is the inverse number of y in Z a. The numbers a and b should be calculated during each step of the Euclidean algorithm, using the received values of those numbers in previous steps and the quotients: a i = a i-2 ... The behaviour of units when they are exponentiated is difficult to study. Modern cryptography exploits this. Order of a Unit. If we start with a unit and keep multiplying it by itself, we wind up with 1 eventually. The order of a unit is the number of steps this takes. The Miller-Rabin Test
