In the event that we want to use PowerShell to check the hash of any file, just press the Windows key and then type PowerShell. An example would be get-filehash c: / file.txt If we choose to use Get-filehash it will use the SHA-256 algorithm, while if we decide to use CerUtil, it will use the MD5 algorithm. With them we can generate the hash of a file. PowerShell’s file hash checking feature supports SHA1, SHA256, SHA384, SHA512, MACTripleDES, MD5, and RIPEMD160, and can be used through Get-filehash and CerUtil. It is a function that we can perform with two default programs that we can find in the PowerSell function. If we do not want to download any program to our computer, we must know that Windows has among its tools an integrated file hash checker. PowerShell, the utility built into Windows for checking hash files MultiHasher is a free application for Windows that we can download from this link. But this is something that we can only do if the file has been previously analyzed. Since this application is integrated into the malicious file checking database of VirusTotal, the famous multi-scanner. To see them, just pass the mouse over it once the calculation has finished.Īnother feature to highlight is that it allows us to know if a file is infected or not infected with a virus. Its use is simple because it is enough to drag and drop any file or folder for the hash or generate one for a text string. It has up to six different algorithm signatures such as CRC32, MD5, SHA-1, SHA-256, SHA-384, SHA-512. We are facing a tool that will help us to verify and generate the hash of a single package. MultiHasher, allows checking for malicious files using VirusTotal QuickHash is a completely free and open source application that is available for Windows, Linux and macOS. For this we can use different programs that we will see below. That is why, another of the functions for which hashes are used is for encryption and storage of passwords, as well as to protect other confidential data from possible spies. In addition, they are irreversible, which makes it more secure, since it is not possible to take a hash and obtain the data that gave rise to it. For example, in the case of SHA-256 its length is 64 characters. The results will always be in a fixed-length string, regardless of the size of the input. One of the main characteristics of Hash is that they are very efficient algorithms and do not require a large dose of computing power to be executed. In general, each of the files that we download from the Internet are verified with the MD5 / SHA256 hash to make sure that the file is not modified or altered. This hash value will always have the same output length, regardless of the length of the input data. The hashes or checksums are a mathematical algorithm that is responsible for transforming any arbitrary block of data into a new series of characters with a fixed length.
