Assuming you use a 2Ghz Pentium processor, the real problem with doing MD5 on a string that large is that (according to my calculations) you'd only get about two-thirds of the way through it before the Sun burned out (~100,000,000,000 years from now) and everything got sort of dark and nippy.

I'm also not optimistic that Windows would run that long with needing a reboot, but I guess it's possible.

Honestly, I've no idea. It's a theoretical concept.

Okay - I missed the actual dimensions of the string length and impact on processing. I'll revise my statement to: that's a wicked big string, and contribute the term wicked to the analysis.



One must use the appropriate terminology.

Hi guys,
as everyone said, md5 algorithm is a one way encryption
you can use tool like this www . stringfunction . com/md5-decrypter . html, it just tried to find the original message using a database

MD5 compare

Hey guys,
Have a similar problem but with more of a solution.
I work in e-mail marketing and just recently have been provided md5 lists (of emails) by clients. But they also provide me with a text file of e-mails. What they expect me to do is turn that e-mail text file to MD5 then compare it with the MD5 file they provide me. Then cross reference the results with the original e-mail file that I have to turn into md5. Then i will have results of the e-mails I need.
Anyone know how to do this, a program perhaps or a way through MAC Terminal?

Stop

Umm sorry I made a mistake :
I only posted the possibilities in md5 & the length of the Bible BUT I didn't post the possibilities in 4970000 characters (the length of the Bible) which is, if the bible consist of only the following charactes: 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', 'é', 'á', 'ű', 'ő', 'ú', 'ö', 'ü', 'ó', '0', '1', '2', '3', '4', '5', '6', '7', '8', '9' (44 different characters) than there are as many as 43619542305367602533268476316997891894997063772604 94013516644218822030418271094879573543095025928177 12662895918319388810000000000000000000000000000000 00000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000 different possibilities (4.36195423053676025332684763169978918949970637726 04940135166442188220304182710948795735430950259281 771266289591831938881 * 10^294) which is larger than the observable universes diameter in mm (8.8x10^29 mm = 880000000000000000000000000000 mm)(calculated at Wolfram|Alpha—Computational Knowledge Engine)

As Dotti said earlier, "Why make your own decoder... Use someone elses on the web." There is so much available code out there... Have you tried to search for something that will work for you?

Same hash

Quote:
Result: "the quick brown fox" becomes:

-> (20x8x5) (17x21x9x3x11) (2x18x15x23x14) (6x15x24)

(combine strings)-> 8001060291738802160

(remove zeros) -> 8162917388216

Decoding: Data has been lost and is scrambled (precluding recovers) and there may be multiple strings that result in a 8162917388216 outcome. if I type in "the quick brown fox" it will always hash to 8162917388216 (so it's good to verify if someone has typed in a correct password) but you cannot reconstruct the string from the hash.
OK. I get it... There is no way of decoding... but... If u hack a db with the passwords coded as above the way to get a password that will be accepted by the system is:
lets just take the "the" word for an example:

the -> 20x8x5 = 800 -> 8
if the password was "the" than the system should accept "h" as the password

h -> 8 = 8 -> 8

(8162917388216 -> h a f b i a g c h h b a f)
