This is a common question with cryptographic algorithms (MD5, SHA1, etc.). The security issues with these algorithms often come from a misunderstanding of what they are and how they work. In this...

The MD5 algorithm is often used to check large files (after a download for example). By comparing the MD5 output, we can tell if they are the same file or not. But is it possible to have the same MD5...

Everybody wants a solution to decrypt MD5 hashs, and Java programmers are also interested :)In this article, you'll learn how to do this, and also discover a few things about the MD5...

MD5 is a hashing algorithm, still popular despite the security issues. You can use it to encrypt a string or to get the fingerprint of a file. In this article, we'll see how to use it in...

MD5 and SHA256 are two popular cryptographic algorithms, used to store sensitive data (passwords for example). In this article, we'll see the difference between them, and which one you should use and...

If you are a developer, you know that regex are really useful to find or check something quickly. But usually, they are not really the easiest thing to do, especially if you are not sure of what you...
