Due to these security concerns, the newer SHA-2 is considered the best cryptographic hash function since no attack has been demonstrated on it as of yet.ДЄs you can see in the screenshot above, the ISO file I am trying to download from Microsoft has a SHA1 checksum listed. This means that malicious tampering can lead to two different files having the same computed hash.

The most common checksums are MD5 and SHA-1, but both have been found to have vulnerabilities. When a good checksum algorithm is used, even a tiny change to the file will result in a completely different checksum value. To verify the integrity of the file, a user calculates the checksum using a checksum calculator program and then compares the two to make sure they match.Д¬hecksums are used not only to ensure a corrupt-free transmission, but also to ensure that the file has not been tampered with. The checksum is calculated using a hash function and is normally posted along with the download. Either way, if you want to ensure that the transmitted file is exactly the same as the source file, you can use a checksum. This can be across the Internet or simply between two computers on the same network. Checksums are used to ensure the integrity of a file after it has been transmitted from one storage device to another. These really long strings basically act as fingerprints for that particular file, whether it be an EXE, ISO, ZIP, etc.

What is a Checksum and How to Calculate a Checksum**ДЄre you wondering what a checksum is? You may have noticed that when you download files from certain websites, they have a very long string of numbers and letters called a checksum or MD5 checksum or SHA-1, etc. The article below from вЂOnline Tech TipsвЂ™ explains вЂChecksumвЂ™ and how it is used to ensure data integrity and some tools to use to work with it. This can be guaranteed by using the вЂchecksumвЂ™ approach as used in many digital data transfers. At Eagle Eye Networks we are often asked about вЂWatermarkingвЂ™ on our recorded video to ensure data integrity.
