MD5 Encryption [vb 2008/.NET]

[KITTKITT20]

song?

[computertrick]

use AES its more secure

[wkdw1ll1ams]

@computertrick considering both can be bruteforced and cant be reversed? there both the same.

[computertrick]

@wkdw1ll1ams If your on about a hashing algorithm now use SHA 1 because MD5 can be cracked easily

I tried to code this but :

Dim ByteString() As Byte = System.Text.Encoding.ASCII.Get­Bytes(content) < here in Content gives me error... I'm using VB2010

[dragonhacks]

thanks a heap hope you dont mund im going to use this as a template to add on eg salt and some other thing

[TeamNRxCOM]

test

[EvanBourne798]

can make hack



[megamt]

@21Mods you can decrypt it, yes.

its the most commonly used hash now, and newer ways of cracking/decrypting/comparing it to actual words or senquences are becoming better and faster.

@LoLFighter1993

Well it's 111881647900000000000000000000­000000000000000. So in the worst case you would need about 466808392000000000000000000 years to crack. (if I did't make a mistake)

thanks for the nice tutor bro...^^

[sahibnarangng]

how can we decrypt gmail password md5 hash code

[Robobbly]

Whats the point of it if it cant be decripted?

[megamt]

@Robobbly it can, trust me

[Robobbly]

@megamt I dont understand - what is the point of MD5 Encryption. couldent you just use your own version or something?

[megamt]

@Robobbly MD5 encryption is ONE of the most used encryption types. depending on length, variety of characters it can be easily cracked, either by copmaring it to a dictionary of other md5 and their outcome or by bruteforcing it which is a 'forced crack' and can take up to years depending on the strength of the hash -- e.g. 7900453de19ad45f0f9693a8febcd4­89 would take years where as 5f4dcc3b5aa765d61d8327deb882cf­99 would take seconds/minutes

[Robobbly]

@megamt I PM ed you the message because it was too long :D

Hey!!!

The Music Name is:

Linkin Park - New Divide

[damustk]

i enjoy all your video man...nice job

[1Mihailo]

music ?

[aeroflighter]

The Music is : Linkin Park - New Divide

!!!:D

[ashutoshgrewal]

Great work man! :) Way to go!

[DerWahreTobi2010]

Google + MD5 Crack GPU (The fastest LGPL GPU MD5 password cracker) ^^ Have Fun! :-)

[DerWahreTobi2010]

With a GPU MD5 Cracker, can you decrypt any Code in 35 Minutes with 4GPUs, also 2 9800GX2

With 4 HD5870, in about, 20 Seconds? xD

Wikipedia

[aydoooo]

"This hash is a permanent string, which can't be converted back to a readable string."

point?

[DjMaddoxX]

The way vb2008 encrypts text to md5 is easy to revert ...

[photographylover246]

@DjMaddoxX actually it's imposable to decrypt MD5 on ANY language!

[MONKEYJUNK987]

good job m8 i didnt know md5 worked with vb

[racicas]

Pleas Hellp my...Thx! Private Sub btnEncrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEncrypt.Click txtOutput.Text = StringToMD5(txtinput.Text)

[SaJi482a]

Yay for Linkin Park - New Divide!

[Sintaxx2]

linkin park sucks... young jeezy much better

[younoob00]

Yes, Brute forging. I didn't remember the word, thanks!

[younoob00]

Nvidia has come with a new tech that hacks md5 in a very powerfull cpu, for ex

a | b | c | d |... aa | bb | cc |... aaa | bbb | ccc|

and with those it makes a md5 of each text and tries to match with the inserted md5, and if it matches it says woala and returns the decoded message. Nice vid btw!

[jnbjabnk]

Do you mean brute forging?

If yes:

Lets say, i've got this string: "The possiblity of brute forcing this string is very low, even under 0 percent" - it contains 77 characters.

Meaning there are 77^36 diffrent posibilities. (36 = 26 letters, 10 numbers)

These are: 1.118.816.479 x 10^49 diffrent posibilities.. so it will take quit long. AND they have to be on the right place. so the chance to bruteforce this is quite low =]

[LoLFighter1993]

@jnbjabnk this would me MUCH MUCH MORE.. if there were just 1.118.816.479 posibilitis i would crack this in 2 seconds! because with GPU-cracker i can crack 760.000.000 / per SECOND!

i just don't know how many possibilities it would be realy :)

[computertrick]

@younoob00 MD5 can be simply cracked with rainbow tables

[younoob00]

@computertrick Indeed they can. Google indexes MD5 sites, so google the MD5 is a protip.

[Darknessknight38]

how do you know that MD5 not can be Decrypted ?

[HDebbo]

Adding a Salt

[chtuncon]

Thanks for the tutorial, I was exaclty looking for that =D

[iXpLiZiT]

You can crack it..

[jnbjabnk]

Sorry, there is just one fail. MD5 Cant be decrypted. and i mean it, doesn't care if there are decrypters, cause these are not real decrypters, a real decrypter, a real decrypter wil revers the proces for a string thats applied with encrypting:

Try to decrypt this: f16f95d3c5baaa4b3fa996e00023cb­84

You can't, cause the hash is not in there database.... so its nog decrypting again... its just a database with all those hashes and pre-encrypted common strings.

[jnbjabnk]

uhh not realy, RSA CAN be Decrypted MD5 CAN'T So it's much more secure...

[GooboyProductions]

it can be decrypted with can and abel

[jnbjabnk]

not realy, and you mean cain & abel :D

well, it's not realy decrypting, cause they have a database with the content. since the MD5 Hash is made up by a string goin through a lot of algorythems, which can't be reversed, which means it can't be decrypted :D

[GooboyProductions]

ccc7a5a1d69d93b215d95fecdc8dc3­d8 = FUCK YOU!

lol jk

[joppe1222222231]

cool!

now make a decrypter to XD

[jnbjabnk]

It cant be decrypted :D

[joppe1222222231]

lolz cool program anyway

[Palkia323]

then whats the point?

[jnbjabnk]

When a for example password is encrypted, the MD5 Hash will always be the same for that password for example: Hello. The MD5 Hash will be: 8b1a9953c4611296a827abf8c47804­d7

So everytime someone types in Hello, it will always return that MD5 Hash

[Palkia323]

okay... if it cannot be decrypted and some1 types: "Whats up?" and it encrypts it... you will never know!

[Auss1Pr1d3]

@jnbjabnk So its not fool proof?

If you make a program with the password as hello but then encrypted it using MD5, rather than trying to guess the MD5 password, i could just attempt to hack the program and find all MD5 hashes in the code and try them all till i got the password. Much more simple way than cracking the MD5 pw. I could be wrong, if so, please inform me.

Good tut btw.
