![]() ![]() Recall that the GCD in Math is short for Greatest Common Divisor and is also called the Highest Common Factor or HCF. ![]() We define our function gcd() which will take two integers: a and b.First we import our modules: random and sympy.Let’s explain what is happening here, step by step: Let’s write some code: import randomĬipher = Messages or data can be encrypted by anyone using the public key, but can only be decrypted by someone who knows the specific prime numbers.įollowing is a simple implementation of the RSA algorithm. The prime numbers are usually kept secret. Someone using RSA encryption would have to create and publish a public key based on two large prime numbers. Recall that a key is basically a string of characters used within an encryption algorithm. In this system of encryption there are two keys: a public key and a private key. AES encryption, alternatively, is a block cipher. The term RSA is an acronym for Rivest– Shamir– Adleman, which are the surnames of its creators. RSA is a public/private key based system of cryptography developed in the 1970s. Let’s do an RSA Algorithm Encrypt/Decrypt Example with Python.
