hmac sha256 decrypt

The HMAC (hash message authentication code) hashes the authorization code, which encrypts the message digest using a key based on the Message digest algorithm (for example, the Md5,sha Series algorithm). It is equivalent to a vest, inside can use MD5

The DH key exchange of SSH is a set of key exchange algorithms for several complex algorithms. The algorithm called Diffie-hellman-groupx-exchange-shax in RFC4419 (there is another simple Rsax-shax switching algorithm). This paper takes

There is not much in the standard library of Python 3 to resolve encryption, but there are libraries for processing hashes. Here we will make a brief introduction to it, but the focus will be on two third-party packages: Pycrypto and cryptography.
