    Default Java Security Quesion

    A simple recursive program can decrypt the MD5 SHA-1, SHA-2 algorithm. Then how these security algorithms are safe?

    They aren't. The only safe way to store your data is to write it down on a piece of paper, put the paper in a jar, and bury the jar in your backyard.

    The question isn't how simple the decryption program is, the question is how long it runs before decrypting it. There are encryption techniques that can be decrypted by even a few lines of code. However even with the most complex programs it still takes 50 years to do so. So that is where the safety lies.

    I thought the same intially...the decryption program will take time. But after exploring for the security. I found that the multi threading java code with JDK 1.7 will do in half a day with more than 2 GB ram machine.
