Hi guys. I am just wondering how it is possible to create two new colliding md5 executable files? In other words, both files have the same hash values.
Appreciate it. Thanks.

I have been searching the Net for an online checksum calculator/tools that can check the efficiency of both md5 and sha1 e.g. speed, accuracy, etc but couldn't find any reliable one. Any suggestions? Many thanks.

By experimentation, or by ensuring that the content of both is the same. Since MD5 hashes are one-way you cannot predict what the result of hashing any content is likely to be.
