Simply, hash algorithms are 1 way only. Encryption algorithms are 2 way.

EDIT - Long answer/example:

Let's use XDA Developers as an example. When you first create your username/password, before storing it in the user DB, the password gets hashed. Then, later when you come back and log on, the system takes the password entered in the login form and hashes it using the same hash algorithm as when the credentials were first created. If the hash from the login form matches the hash in the database, then vBulletin knows that you supplied the correct password.

However, if an XDA admin went through the user database, there would be no way for them to take the hashes stored in the DB and get the original, plaintext password.

Now, in the same scenario, lets use encryption. This time, when the password is first created, an encryption key would be used, and along with the encryption algorithm, ciphertext for the password would be generated and stored in the DB. Now, when the user comes along again and tries to logon, we could again just use the encryption key/algorithm and encrypt what the user entered in the form, and compare it against the ciphertext stored in the DB.

But now, if an XDA admin went directly to the user DB, they could use the decryption key along with the ciphertext stored in the DB, and convert it back to the original, plaintext password.

Summary - Use hashes when you just need to verify something. Use encryption when you need to go from plaintext -> encrypted text -> back to plaintext.

Blagus,

I'm nowhere near a security expert either, but I believe ryocoon has the right idea.

I don't know exactly what you're up to, but it sounds like you have some sort of value that's currently hashed, and you want to know what that value is.

If you have a list of hashes and the values they represent then yes, by all means, see if the value for the hash you're trying to crack is in the table. Hopefully SE made it easy on us!

But generally, Rainbow Tables aren't really that useful, if you do some pretty easy things. The easiest thing to do is add a "salt" to the value being hashed, which will change the resulting hash for the value. So if they've salted the value that you're searching for, unless the rainbow tables were made using the same hash algorithm and salt on the values, the tables likely won't have the correct hash for the value we need.

Your best case scenario is that the value that hash represents is something meaningful or common or a pattern in some sort of fashion, as I think what's likely to be found in rainbow tables on teh internetz are common values for passwords.

Your worst case scenario (I think, getting to edge of my knowledge) is that they used a random # generator to generate both the value and the salt.

Somewhere in between is a value that is some sort of pattern plus a salt.

To attack the problem in this regard (obtain original value from known hashed value) we probably need to know two things, the hashing algorithm (ie. MD5, SHA1, SHA256) and the salt they used. Then we can generate rainbow tables for the in between case, and hope for the best.

Theoretically, there are other methods of attack, given other knowns about the situation.

Exploit flaws in the hashing algorithm. The "Cryptanalysis and validation" section of the SHA-1 Wikipedia article and the "Security" section of the MD5 can shed light on this topic

Exploit flaws in the software (I hope the bootloader!) using the hash. I don't totally understand whats going on here in this article, but it mentions how Nintendo screwed up badly in their implementation of RSA encryption, so that you could easily generate a hash that would pass with a value that wasn't the correct value.

These solutions, however, are beyond my knowledge level. Good luck!

hash analyzer i got in pm says it's size is 64 and can't find the hash algorithm.

c&a says it's sha-256. resulting value should be 16 char long 0-9, A-F but it's taking too long to decrypt. (+500,000 years) even with specified size and charset to use...

how do i generate a list from

0000000000000000

to

FFFFFFFFFFFFFFFF

for dictionary attack? i'm too bored to google on phone :P

...being in hope it's not salted...
[Xperia Play Android Development] Mogul345:
Are you a Windows or *NIX guy?

Microsoft's .NET framework includes a bunch of classes to generate hash values in the System.Security.Cryptography namespace. They've got classes for generating SHA256 hashes. I could see this taking a while to do though. Would definitely have to make the app multithreaded to max out CPU usage. That's a whole lot of hashes to compute.

What kind of format do you need the data in? Flat file, maybe tab delimited?
[Xperia Play Android Development] Mills00013:
It would probably be better to hand off the dictionary attack to CUDA or gpu processing so you can get a lot more done.

You're not trying to raw attack the unlock command, are you?
[Xperia Play Android Development] Blagus:
here's more info:

i'm not hacking the phone. i just take what i believe at least 80% is the hash of bl unlock code - knowing SE security scheme, it most probably is.

if bl is already unlocked, i can also take bl unlock code.

but now, if i hash it to sha-256, what cain claims hash to be, i have two different hashes.

so i assume it can be salted.

i have 3-4 examples, so i have some material to work with.

*wish there was app which could analyze all (hash, salt, etc.) by providing original value and the hash.*

SE unlock site generates it from IMEI but this thing on phone is probably the checking-hash. i have no idea what else that could be since it doesn't exist on sim-locked phones which aren't made to be unlocked anyways. it exists only on fastboot capable xperias.
[Eee Pad Transformer Q&A, Help & Troubleshooting] myxmastrmike:
Ok, ive got a slightly different issue.

I just got my Tranmsformer a couple days ago, and when I first powered it on it did an OTA update to I believe .13. I ended up downgrading using this youtube vid http://www.youtube.com/watch?v=tzpj9leRawg and am now showing build number: HRI66.WW_epad-8.2.2.6.1-20110325

I tried updating to 8.2.3.9 using this tutorial ( http://dlcdnet.asus.com/pub/ASUS/Eee...her_SOP_WW.pdf ) but when I put the sd card into the slot, I never get the alert for system update file detected....

So I guess my question is two fold...

A. Is there simple one-file root option for 8.2.2.6 like there is for 8.2.3.9?

B. If not, how in the heck do I get from 8.2.2.6 to 8.2.3.9!? LOL

Thanks!
[Epic 4G Q&A, Help & Troubleshooting] tazfanatic:
I have a strange issue and I am trying to recall if it happened well on srf 1.0 but I can't recall I think it did. When I plug my phone into charge during the day sometimes and i stress sometimes the charging icon starts to blink red and starts to discharge this happens with none standard usb cable into different computers or with the standard plug wall charger. I am on srf 1.1.1 with extended battery. I have fully charged ran battery calibrate apk and fully drained. I am thinking my extended battery might be defective but not sure. But a reboot fixes the issue for at least one attempt at charging. Any ideas?
[Epic 4G Q&A, Help & Troubleshooting] maxertx:
I was using a HTC usb cable and I was loosing more battery it would never go above 75%. Changed cables and now it works better, but I did see the discharge icon also...
[Epic 4G Q&A, Help & Troubleshooting] tazfanatic:
this happens with 2 different cables. I am going to test with stock battery to see if it happens. think it might be a bad extended battery or something with the rom that doesn't like the extended battery. Not sure that last part makes an sense but that is what it almost seems like.

[Epic 4G Q&A, Help & Troubleshooting] tazfanatic:
So far unable to duplicate with stock battery. This should be fun trying to get a replacement extended battery. Or could this be a ROM issue with the extended battery? I know the only way to test is go back to stock to see. Now with that said I am will to test next week but I do have a question. I have a nanbackup when I reconvert to ext4 with cwm 3.0.2.5 I should be able to recover that right? Me switching back and forth from ext to rfs and changing cwm version shouldn't do anything?
[Epic 4G Q&A, Help & Troubleshooting] tazfanatic:
I think I found out what part of my problem is. I think most of it had to do with EE03 modem and/or twilight kernel. I restored from my nanbackup installed Vision kernal and flashed back to ec05 and have had no problems. The nanbackup was created after the fresh install of SRF 1.1.1 w/twilight so I went back to my stock setup with no tweaks. Also found out about the DRM and SNS stuff draining battery life so I froze those in Titanium all is good now!

[Samsung Infuse 4G] eatjello:
Of course we need one of these threads.

I'm going to go buy a full body BodyGuardz this weekend and i'll report back with pictures, and a review. I've had a lot of bodyguardz for various phones, and they cover the best. They have the orange peel and sticky feel on the screen, but not nearly as bad as i've seen on Zagg. I've never once been satisfied with zagg.

I've tried Stealth Guards on my iphone and desire Z, and the screen protector is a good texture, feels smooth, no resistance. But they don't cover enough of the body.

Never owned BSE

I've had a Skinomi, and they have the same texture as the Stealth guards, but they seem to be very vulnerable to peeling. Also not enough body cover. (might as well buy the stealth guards, they're cheaper)

Anyone got any yet?
[Samsung Infuse 4G] pixelkore:
I just Installed Skinomi full body. I've had no issues so far and I like the results. I followed the direction to the T, but added the extra step of applying the protectors in a steam up bathroom. Helps minimize dust, and the stream aids in installation).
[Samsung Infuse 4G] eatjello:
do you mind posting some pictures?
[Samsung Infuse 4G] pixelkore:
After work I will post some pictures, I have the product pictures on me right now. Another thing is the product states that once applied to at least allow 12-24? hours to use. I am using it less than that, probably a bad move on my part. So far no problems, we'll see by the end of today.

I bought two, one for my Infuse(full body) and Inspire(screen only).
[Samsung Infuse 4G] pixelkore:
Skinomi full body.
[Samsung Infuse 4G] eatjello:
thanks for the pics! the screen protector looks awesome. the full body could be a bit larger. the back looks funny haha. but i really like that screen protector, i've always liked skinomis compared to other brands.
[Samsung Infuse 4G] pixelkore:
Thanks. Ya I could do it again but pull'em tighter. But I am very satisfied. I was surprised by how the body peices held up, I figured they would peel off in my pocket, but no problems. The only con's I can think of is there are some thin exposed parts of the phone, imprint of object or finger nail leaves dimples but fade smoothly; slowly. If applied correctly it will last.
[Samsung Infuse 4G] eatjello:

[Samsung Infuse 4G] eatjello:
i got a invisible shield from best buy because i was impatient and didn't want to wait for shipping. they don't have the full body, so i got the screen protector.

i just finishd putting it on, the texture is different than previous zaggs i've used. also there are a bunch of horizontal lines evenly spaced (they were there before i put it on, not scratches) which you can see at certain angles. and they also have a little zagg logo on the bottom right of the screen protector.. that's new.. and annoying. it's hard to see, but since i know it's there. i don't like it -_-

i'll take some pictures when i can, but overall it's the same resistant non smooth that i dislike about zaggs.
[Samsung Infuse 4G] hoofadoo:

[Samsung Infuse 4G] eatjello:
i noticed that about the screen protector too. i'm thinking about returning mine tomorrow. if you go today, let me know how it goes.

i also just ordered a skinomi full body, and a stealthguards full body. i can't get my camera to focus well on the invisible shield enough to show the logo, (black on black >_>)

edit: here are some pictures of the invisible shield. if you look at the first picture, you can see the lines on the film, those lines transferred over to the shield and look exactly like that -_-
[Samsung Infuse 4G] hoofadoo:
I have the horizontal lines too... They don't really bother me, and maybe they will fade. They seem like they are anyway...
[Samsung Infuse 4G] eatjello:
alright guys i'm going all out lol.

So what i have shipping

Stealth Guards (10$ + 2$ shipping)

Skinomi (15$ shipped with coupon (orig 20$))

Invisible Protection (ebay 10$ shipped)

Naked Shield (ebay 5$ Shipped)

All full body

I'll probably start with the stealth guards since that's the only one that comes with 2 full sets. Then go to Naked Shield, and Invisible Protection, and then Skinomi.

Naked Shield and invisible protection look pretty much exactly the same. So i'm expecting similar results from them.

I'll take pictures of all of them, packaging, installed, etc.

Also, Update on the invisible shield. All the bubbles are gone, those god damn lines are still there though. Extremely irritating. And the cutout at the top that isn't pictured on the box pisses me off. The smooth swype movements are now gone too, the skin is sticky, it's hard to play games too. ugh i hate invisible shield.
[Samsung Infuse 4G] briansj:
Tried the skinomi sceen protection. It's very hard to put on and very easy to mess up. There is only one film and it's matte screen. I ended up throwing it away because it degrades the infuse beautiful screen. Any recommendation ?
[Samsung Infuse 4G] pixelkore:
Sorry the Skinomi didn't work out for you. Matte screen? I never saw that from skinomi. If done correctly it looks as if it weren't there.

Yeah. Ordered from Amazon http://www.amazon.com/Skinomi-TechS...JRRS/ref=sr_1_4?ie=UTF8&qid=1307469130&sr=8-4
