rudi Posted May 25, 2009 Share Posted May 25, 2009 Hi.How do i decrypt a incoming MD5 string?MD5 hashes cannot be decrypted. Google will show you several results for sites offering a chance to find POSSIBLE strings fitting to a given MD5 check sum.Keep in mind, that a MD5 sum has always the same, fixed length, no matter whether you feed the MD5 algorithm with the string "abc" or with a long, long text, e.g. J.R.R. Tolkien's "Lord of the Rings".For "abc" you might expect, that a decrypting could be possible. But for a 3 volume novel it's obvious, that there is no way at all to "decrypt" more than 1000 pages from a one line string Regards, Rudi. Earth is flat, pigs can fly, and Nuclear Power is SAFE!

James Posted May 26, 2009 Share Posted May 26, 2009 The websites Rudi mentioned only use a dictionary attack or brute force. A dictionary attack will reverse lookup the text matching already encrypted text.Example of this:abc = 123456789cba = 132456789 (different)bca = 142356789 (different again)The user wants to decrypt 142456789, the website will look for that encrypted text and find the original. It does not use an algorithm to decrypt it (MD5 cannot be decrypted). Blog - Seriously epic web hosting - Twitter - GitHub - Cachet HQ Link to comment Share on other sites More sharing options...

James Posted May 26, 2009 Share Posted May 26, 2009 I know, I'm emphasizing the point. Blog - Seriously epic web hosting - Twitter - GitHub - Cachet HQ Link to comment Share on other sites More sharing options...
