Good question!!!!

I was thinking exactly the same months ago. Some of you involved in IT may know that the last "solid" cryptographic algo was MD5. However, years after its usages flaws were found in it. Then SHA crypto algos appeared and now they are solid. However, I am 99% sure after 20 years a flaw into them will be found as well. IT world is constantly developing race between hackers and security programmers.
