You can share the hash values generated with the recipient to let them validate your file. While I show a text file in the screenshot, you can verify any type of file or generate a hash for your files before sending it to someone else. It only takes a few clicks to protect yourself against malicious or tampered files. When using Collision, you just add the file that you need to generate a hash value or verify it. If you are not aware of it, our tutorial on verifying checksum in Linux should help. Without a GUI, you will have to use the terminal to generate hash values to compare/verify.Ĭollision makes it incredibly easy, without needing to launch a terminal or knowing to generate checksum values of a file. Collision: Easily Verify a File and Spot Malicious Files While discussing hashing is beyond the scope of this article, it is important to know that it comes in handy when verifying the integrity of a file. And, this is how encryption makes things secure. Suppose an attacker gets hold of the database with hash values (instead of the real information), they cannot make sense of it. It’s primarily used in encryption, where every file/information is stored securely as hash values. So, even if a tiny bit of the file changes, the hash value changes entirely. If you are curious, you can refer to our guide on verifying checksum in Linux.įor every information/file, there will be a unique hash value (or checksum). This helps you confirm whether the file has been modified or not. A hash function (such as SHA-1) is a checksum if it is used to verify a file. That’s where cryptographic hash functions come in. Moreover, how can you verify that the file comes from an original source? Someone sends you a file, how do you verify that it’s the original one meant for you? How can you be certain that it hasn’t been tampered with? B rief: A GUI program to let you check hash for your files to ensure that it is not malicious and true to its source.
