Cracking MD5 hashes is interesting for many people, and if you are programming in JavaScript you are at the perfect place. In this article, you’ll learn how to use MD5 in JavaScript and also how to decrypt MD5 hashes. The MD5 hash function works in one way only, there is no reverse function, whatever the…
That’s a common question when you work with hashes for the first time. I’m not (yet) native speaker in MD5, but I think I can help you to guess if a hash you have is a MD5 or not. The MD5 algorithm generate 128-bits long hashes, generally represented in a string of 32 hexadecimal characters….
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 article, we’ll especially look at the MD5 algorithm and if it can be decrypted or not. As a general rule, the MD5 algorithm…
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 hash for two different files? That’s what we’ll see in this article. Two files can…
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 algorithm. The MD5 cryptographic algorithm only works one way. It’s possible to crypt a word into MD5 with Java, but there is no…
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 PowerShell. PowerShell offers a cmdlet to generate MD5 hash for a file: Get-FileHash. It can also be used…
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 why. As a whole, SHA-256 is better than MD5 because the output size is twice longer and the probability of collisions is lower….
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 are looking for. That’s why I wrote this article, to give you the guidelines but also a…
If you are still using MD5 to encrypt passwords in a database, it might be a right move to look for a better algorithm. SHA256 should be a good replacement, and the question today is to see how to migrate from MD5 to SHA256. As a general rule, MD5 is a hashing function, not an…
Sometimes, when you download a file on the Internet (program, image, etc.), you might get another file with it, with a md5 file extension (ex: myfile.iso and myfile.iso.md5). If you don’t know what to do with this file, you’re at the good place, I’ll explain everything in this article. An MD5 file is generated to…
