高效的在线校验和工具 [英] Efficient Online Checksum Tool

问题描述

大家好.我一直在网上寻找可以检查md5和sha1效率的在线校验和计算器/工具，例如速度，准确性等，但找不到任何可靠的方法.有什么建议?非常感谢.

Hi all. I have been searching the Net for an online checksum calculator/tools that can check the efficiency of both md5 and sha1 e.g. speed, accuracy, etc but couldn''t find any reliable one. Any suggestions? Many thanks.

推荐答案

...并且，如果您想自己实现这样的工具，作为Web或桌面应用程序，这特别容易，尤其是使用.NET时. .请参阅:
http://msdn.microsoft.com/en-us/library/system. security.cryptography.hashalgorithm.aspx [ ^ ].

此外，如果您想自己发布校验和，请记住MD5和SHA1均已损坏，因此恶意艺术家可以将其与软件本身一起伪造(将其转换为带有病毒或间谍的恶意软件).代理人).相反，我建议使用SHA-2系列中的一种加密哈希函数.请参阅:
http://en.wikipedia.org/wiki/Cryptographic_hash_function [ http://en.wikipedia.org/wiki/MD5 [ http://en.wikipedia.org/wiki/SHA-1 [ http://en.wikipedia.org/wiki/SHA-2 [

…And if you want to implement such tool by yourself, as a Web or desktop application, this is quite easy, in particular, with .NET. Please see:
http://msdn.microsoft.com/en-us/library/system.security.cryptography.hashalgorithm.aspx[^].

Besides, if you want to publish a checksum by yourself, keep in mind that both MD5 and SHA1 are found broken, so a malicious artist can potentially fake it along with software itself (turning it to a malicious software, with a virus or a spy agent). Instead, I would advise using one of the cryptographic hash functions from the SHA-2 family. Please see:
http://en.wikipedia.org/wiki/Cryptographic_hash_function[^],
http://en.wikipedia.org/wiki/MD5[^],
http://en.wikipedia.org/wiki/SHA-1[^],
http://en.wikipedia.org/wiki/SHA-2[^].

Please don''t blame me for answering a wrong question. Here is the thing: you did not ask a question about programming, did not tag platform, language, etc. But if the question is not about programming, it should be removed as off-topic. This forum is not for computer users who need to check up the checksum of downloaded software, it is for the developers.
