Verify the Integrity of the Software using MD5 HASH


The MD5 Message-Digest Algorithm is a widely used cryptographic hash function that produces a 128-bit (16-byte) hash value. MD5 has been employed in a wide variety of security applications, and is also commonly used to check data integrity. It is widely used by publishers of downloadable material on the internet to ensure the authenticity of the downloaded content. To do so the publisher supplies the hash value together with the download link to the file. The user is then able to compare the two values after download by calculating the MD5 hash value of the downloaded file. There are some utilities available on the Internet for free download that will calculate these digests.

When downloading programs from mirror sites, it’s always a good idea to check the integrity of those files, to ensure that nobody has altered it either accidentally or maliciously. Let us check the small MD5 program "MD5 calculator". The MD5 Calculator is a program that will enable you to right click any file and select "MD5 Calculator" from the context menu. This will calculate the MD5 value of the selected file. You can compare the calculated value to a value given to you by another person or from a web site.

You can compare the calculated value to a value given to you by another person or from a web site.

Let us check the MD5 checksum of the yahoo messenger program available for download from the Filehippo Website, The yahoo messenger version 11.5.0.192 which has a MD5 checksum is C42122994FA9ADC2732B1CEAD17F47C4.




After downloading the software check the hash with MD5 calculator.



The MD5 Digest field contains the calculated value. If you want to compare this MD5 digest to another you can paste the other value into the Compare to the field. The MD5 checksum listed in the filehippo site should match with the download program checksum.




MD5 calculator compare the  checksum listed in site  with downloaded program, the equal sign shows the integrity of the software is matched.
