In this part, you are required to implement the textbook RSA algorithm from scratch. It contains the following three procedures, KeyGen, Encrypt, and Decrypt. Your program does the following: Note that in this program, you may only include third-party codes or libraries for: Miller-Rabin Test...
Note that in this program, you may only include third-party codes or libraries for: Miller-Rabin Test Extended Euclidean Algorithm Recall that including any third-party codes without claiming is considered as lack of academic integrity, and results in failing this course.

下面代码演示了 RSA 的使用方法：import rsa# Bob creates a key pair:(bob_pub, bob_priv) = rsa.newkeys(512)# Alice ecnrypts a message for ..., bob_pub)# When Bob gets the message, he# decrypts it with his private key:message = rsa.decrypt(crypto, bob_priv)print(message.decode( utf...
hashlib - Secure hashes and message digests This module implements a common interface to many different secure hash and message digest algorithms. Included are the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm...
