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…

The main goal of MD5 was to hide sensitive data like passwords by encrypting it in a database, so that even if the database is downloaded by someone, there is no way they can get all the passwords directly. The MD5 algorithm has been created especially to not have a reverse function. Why? MD5 is…

The MD5 encryption algorithm is still one of the most used in the world, and specially in MySQL tables.In this tutorial, I’ll show you how it works in a database, and especially how to generate it easily with PHPMyAdmin. When inserting a new line with PHPMyAdmin, there is a dropdown menu on the left of…

Do you wonder how to generate a MD5 file checksum? You are at the best place, in this article, I’ll show you 7 methods to do this, so you’ll necessarily find one that works for you. As a general rule, the MD5 checksum for a file can be generated with a command line or third-party…

MD5 and SHA1 are often used following a random pick by the developer, but it’s not the same thingIn this post, I’ll introduce these two solutions and explain how they differ. The main difference between SHA1 and MD5 is that MD5 produces a 32-character message digest, while SHA1 produces a 40-character hexadecimal. Also, the MD5…

You probably already read that information, and you know that MD5 is not the most secure hashing functionBut do you know why? Do you know safer alternatives?This is what I’ll explain you today. Why is MD5 not secure?MD5 is a cryptographic algorithm, often used to store passwords in a databaseBut this algorithm is no longer safeBrute force…
