Title: Plugin zip file checksums vary Last modified: August 21, 2016 --- # Plugin zip file checksums vary * [temptempted](https://wordpress.org/support/users/temptempted/) * (@temptempted) * [12 years, 4 months ago](https://wordpress.org/support/topic/plugin-zip-file-checksums-vary/) * Hello * Is it normal to get different checksums for the same plugin’s, same version zip file at different times? I’ve tried using various systems and also online md5sum tools. For example contact form 7: * [http://downloads.wordpress.org/plugin/contact-form-7.3.6.zip](http://downloads.wordpress.org/plugin/contact-form-7.3.6.zip) * Some of the md5sums I’m getting: * 360f187336194dde8961160c585ba413 ../contact-form-7.3.6.zip a131a53a63f667d00061ba089c10e2c1../ contact-form-7.3.6.zip.1 501b5a06217f9c904078a789809a321e contact-form-7.3.6( 1).zip * Download this file and do an md5sum. Then wait a few minutes, download it again and do another md5sum. Repeat again. You will find a different md5sum is generated. Is this because the plugin zip files are dynamically created?

So only the zip-files differ, not their content. This is bad for security aware people, because you cannot easily distinguish between original and man-in-the-middle changed files.
