SHA-512 is the most secure member of the SHA-2 family. It makes a 512-bit hash value. Programmers use it for high-throughput applications, such as checking data integrity. The code below shows how to generate a SHA-512 hash with thehashlibmodule in Python: hash_object=hashlib.sha512(tex...
New attribute: the hashlib module now has an algorithms attribute containing a tuple naming the supported algorithms. In Python 2.7, hashlib.algorithms contains ('md5', 'sha1', 'sha224', 'sha256', 'sha384', 'sha512'). (Contributed by Carl Chenet; bpo-7418.) The default HTTPResponse cla...
On Linux, os.urandom() now blocks until the system urandom entropy pool is initialized to increase the security. See the PEP 524 for the rationale. The hashlib and ssl modules now support OpenSSL 1.1.0. The default settings and feature set of the ssl module have been improved. The hashlib...
1 使用python编写的代码(.py文件) 2 已被编译为共享库或DLL的C或C++扩展 3 包好一组模块的包 4 使用C编写并链接到python解释器的内置模块 为何要使用模块? 如果你退出python解释器然后重新进入,那么你之前定义的函数或者变量都将丢失,因此我们通常将程序写到文件中以便永久保存下来,需要时就通过python test.py方式...
Many old modules were removed. Some, like gopherlib (no longer used) and md5 (replaced by hashlib), were already deprecated by PEP 0004. Others were removed as a result of the removal of support for various platforms such as Irix, BeOS and Mac OS 9 (see PEP 0011). Some modules were ...
The core MicroPython includes implementation of several standard Python 3.4 libraries, which consists of an array, binascii, builtins, cmath, collections, errno, gc, hashlib, heapq, io, json, math, os, random, re, select, socket, ssl, struct, sys, time, uasyncio, zlib, and _thread. Oth...

Mostoperating systemsinclude built-in commands or utilities for hashing. For instance, aLinuxor macOS user might type: shasum -a 256 example.txt Windows users often rely on certutil: certutil -hashfile example.txt SHA256 Programming languages also offer libraries for hashing. Python’s hashlib mod...
