C++对象布局及多态探索之菱形结构虚继承 - C/C++ - 清泛网 - 专注C/C++及内核技术
C++对象布局及多态探索之菱形结构虚继承这次我们看看菱形结构的虚继承。虚继承的引入本就是为了解决复杂结构的继承体系问题。上一篇我们在讨论虚继承时用的是一个简单的继承结构，...这次我们看看菱形结构的虚继承。虚...
Calculate RSA key fingerprint

Run the following command to retrieve the SHA256 fingerprint of your SSH key (-l means "list" instead of create a new key, -f means "filename"):
$ ssh-keygen -lf /path/to/ssh/key
So for example, on my machine the command I ran was (using RSA pu...

CRC32 is pretty fast and there's a function for it: http://www.php.net/manual/en/function.crc32.php
But you should be aware that CRC32 will have more collisions than MD5 or even SHA-1 hashes, simply because of the reduced length (32 bits compare...

SHA1 vs md5 vs SHA256: which to use for a PHP login?
I'm making a php login, and I'm trying to decide whether to use SHA1 or Md5, or SHA256 which I read about in another stackoverflow article. Are any of them more secure than others? For SHA1/256, do I still use a salt?

What is the fastest way to create a checksum for large files in C#
... is that SHA256Managed reads 4096 bytes at a time (inherit from FileStream and override Read(byte[], int, int) to see how much it reads from the filestream), which is too small a buffer for disk IO.
To speed things up (2 minutes for hashing 2 Gb file on my machine with SHA256, 1 minute for MD5) wra...
