![]() To put the long story short they found two different files which produced the same value or SHA-1 hash but are in reality different. Some researchers have found out collisions with MD5 and SHA-1 functions. Keep in mind that these hash functions are not perfect at all. ![]() If due to download issues or hard drive issues a random occurs then the resulting checksum shall be different even if the error is small. These make sure that files do not carry any kind of error. The differences between MD5, SHA-1/256 Checksums Like Linux distributions provide these so that we can verify that Linux ISO has been downloaded properly before it is burned to a disc or put in USB.Ĭheck the integrity of any type of file, documents and even media with this, all you need to know is its original file. If the results match then the file you carry is identical.ĭifferent systems use checksum style techniques to check data for issues occurring in the background but these can be done by you as well. Now, if you have the know-how of this in the original file then what you can do is run hashing utility on this. These are used to check files and data for errors that usually occur during storage or transmission due to network issues a file is not downloaded problem can result in disk or file corruption. Why you should use Checksums and are they good
