sha1 hexdigest

First, let's introduce the concept of MD5 and SHA1.MD5The full name of MD5 is message-digest algorithm 5 (Information-Digest algorithm). 128-bit length. At present, MD5 is an irreversible algorithm.It has high security. It corresponds to any string

Digest algorithm MD5, SHA1 introduction and application instance code in Python, pythonsha1 For algorithm learning, I think most of the algorithms in programming languages are in the same place. The main aspect is to understand what this algorithm

Because of different languages, the rules for encryption are slightly different. Then this problem in the Niang can not search a correct answer, hereby record. 1. First, the two basic algorithms need to be consistent, here are the basic rules of SHA1

HashlibThe Hashlib module in Python is used for hashing or MD5 encryption, and this encryption is irreversible, so this algorithm is called the Digest algorithm. It supports all the algorithms provided by the OpenSSL library, including MD5, SHA1,

Using Python for file hash calculations there are two points to note:1, file Open the way must be binary mode, both open the file when using B mode, or hash calculation is based on the text that will get the wrong file hash (online to see someone
