About MD5 hashes/checksums

No matter what you call it, either hash or checksum, MD5 is a way to get a smaller representation of a larger string. The idea is to get a unique value that represents the whole. It’s like a UPC of a product for a file. If you generate a hash of a file, then send it to your friend, they will generate the same hash of the file if it has not been altered. If it has been altered in the slightest, the hash will be different. Note that the hash is of the contents of the file. If the name changes, then the hashes will still be the same. It is also important to note that MD5 is not perfect. It will not create a totally unique hash, meaning collisions may occur where two distinct files create the same hash. The chances of this happening however is low enough that if you’re trying to compare files after a transfer, you’re safe to assume a collision will not occur. If you’re comparing hundreds of thousands of files or more, your chances increase that two of them may collide. Wiki has an educational article if you want more technical details.
