The generatepublickey function's parameter is private key. I find the public key is generated by hashing private key in your code. I find the public key is generated by hashing private key in your code.

You can also use sep256k1 library in Python to ecdsa sign and verify. The public and private keys are the keys generated from Bip32 specifications and seed from Bip39 specifications.

In this chapter, we will focus on step wise implementation of RSA algorithm using Python.
Generating RSA keys
The following steps are involved in generating RSA keys −
- Create two large prime numbers namely p and q. The product of these numbers will be called n, where n= p*q
- Generate a random number which is relatively prime with (p-1) and (q-1). Let the number be called as e.
- Calculate the modular inverse of e. The calculated inverse will be called as d.
Algorithms for generating RSA keys
We need two primary algorithms for generating RSA keys using Python − Cryptomath module and Rabin Miller module.
Cryptomath Module
The source code of cryptomath module which follows all the basic implementation of RSA algorithm is as follows −
RabinMiller Module
The source code of RabinMiller module which follows all the basic implementation of RSA algorithm is as follows −
The complete code for generating RSA keys is as follows −
Output
The public key and private keys are generated and saved in the respective files as shown in the following output.
