Could the MD5 be changed? How to change the MD5?
md5sum calculates and verifies 128-bit MD5 hashes. The MD5 hash functions as a compact digital fingerprint of a file. It is very unlikely that any two non-identical files in the real world will have the same MD5 hash, unless they have been specifically created to have the same hash.
md5sum is used to verify the integrity of files, as virtually any change to a file will cause its MD5 hash to change. Most commonly,
md5sum is used to verify that a file has not changed as a result of a faulty file transfer, a disk error or non-malicious meddling.

No. You can not change
md5sumof a file as long as the contents of the files are same. And that is the sole purpose of it. You can change the
md5sumvalue of a file by making any change in its content only.
