What is MD5 hash?
MD5 hash is also known as checksum for a file that produced in 128-bit value. The concept of MD5 hash value of each file is similar like fingerprinting of human, where each file has its own unique hash value and it is highly impossible that two different files can have the same MD5 value.
MD5 hash is commonly performed as a data checking method for integrity or completeness of files.
For example, if you want to know whether your downloaded file is corrupted or completed, you can do it through calculating MD5 hash of your file and compare with the MD5 hash value provided by the uploader. The value should be same if both files are identical, unless it is corrupted.
For Mac OS:
1. Open Terminal.app from your application folder OR search Terminal from spotlight search.
2. Once terminal opened, type “md5<space>” and drag your file into terminal window.
3. Press enter and it will provide you the MD5 hash value of your file. The long string of numbers and letters are the hash value of your file.
For Windows user:
You will need to use third party programme to check MD5 hash. There are many softwares that can be used in Windows. Personally, I use MD5 checker (Free) from TSoft and I find it simple, easy to use, functional with relatively small size. No installation is required to use the software.
