Another cool function is MD5(). Currently there is (I believe) no way to decrypt MD5 encrypted information. So what is it good for?? Mostly checking for known quantities. e.g.
MD5 is not encryption, MD5 is a hash algorithm that returns a hash value. The hash value is always 16 letters, even if the source is 2 GB then the result is 16 bytes so of course you cannot decrypt it because its not encryption at all.
For the 2 GB of data then you can think of the MD5 as its fingerprint to identify it. But other than that it does not represent the original data.
