Decode A Sha1 Encryption


Jan 7, 2007

I decided to sha1 passwords into the database for the creation of a user account. When logging into the system, this sql statement works, but I can't figure out how to reverse it, so I'm assuming this is a one-way encryption: PHP Code:

$sql = "SELECT email, password, first
FROM `account`
WHERE `email` = '" . addslashes(htmlspecialchars($AdminID)) . "'
AND
`password` = '" . sha1(addslashes(htmlspecialchars($AdminPswd))) . "'";

I need to have a statement to retrieve the encryption and decode it for password retrieval (when a user lost their password). Is there a way to decode this or should I choose another encryption technique (2-way) other than the basic base64_decode/base64_encode?

Security - Custom Sha1+salt Pass Decode?

my answer was answered about password protection(php users passwords protection) and my final code:

function sha1_custom($string) {
$salt = sha1("1".$string."1");
[code]....

Let's say for strongest security, I want to encrypt IP, signup date, just everything. But in admin panel I want to retrieve that info, so it means I need decript itIs it possible from this script/function to make a decrypt script/function?

Encryption - Use Sha1 Or Others Version Of Sha?

I am going to generate a random password for my users. Probably I will use salt and sha1 method. But I found that there are other version of sha1, like sha256, sha512 etc.

What is the differences between the sha versions? Which one better, more secure, and faster (performances)? Which one should I use?

Logging In With Sha1() Encryption?

I added this to my sign up code :

$password=mysql_real_escape_string(sha1($_POST['password']));

and now it inserts the password into the database while its encrypted. But signing in doesn't seem to work anymore. Here is the login code.

function checklogin($username, $password){
global $mysqli;
$password=sha1($password);

Encryption - Inserting Data Into A Database Using SHA1

Another n00b question but when inserting data into a database using SHA1 do you need to do this: PHP Code:

INSERT INTO $table (`password`)
VALUES([b]'sha1($_POST['password'])'[/b]);

or something like that, and when retrieving from it: PHP Code:

SELECT * FROM $table WHERE sha1($_POST['password']);

Or can you just got $_POST['password']
Sorry I dont know how this works. Also what is a snippet for salting a sha1 command.

Encryption - Decode A Script Encoded With 'zend Guard'?

We have a website maintained by an old employee and it appears it's encoded by Zend Guard including all backups.I know a little about Zend Optimizer, but never considered it for source protection as I know in the end the bytecode will need to be decoded for the interpreter, and was sure people easily decode optimized files using some software. Now I need to decode some files and I can't find anything but some 'paid services'. We have the ownership of the code and are locked out now for any changes and debugging. How can I decode our files back?

Difference In CodeIgniter Sha1 And Normal Sha1?

What is difference in CodeIgniter sha1 and normal PHP sha1? For example:

And

$normal_hashed = sha1("test");

Both will return same values. Where does CodeIgniter uses encryption_key?

MD5() And SHA1()

I realise that both these functions encrypt to a hash of 32 and 40 chars respectively and see the SHA1() is more crytographically secure than MD5() but in the real world just how secure are they? Can they be hacked? I.e on my site what I want to do is protect both user and pw BEFORE calling a MySQL stored procedure which will then do something else to them in the Db.

My idea is that then it is secured during and after transit from web server to Db. So if I say SHA1'd user and pw(making sure the password is a alphanumeric string) before calling MySQL, if someone picked them up using a sniffer etc could they work them out?

Sha1 Or Md5?

Md5 And Sha1

I'm building a registration/login script:

$result = "insert into users (username, password, email) values ('$username', sha1('$password'), '$email')";

I've tested this out by submitting (username1, password1) and (username2, password2) Both "password1" and "password2" are encrypted to the same string:

MD5 Encryption Compatibilty With C # Encryption?

I am in the process of try to integrate some C# ASP.NET webservice into my PHP application however there is a big problem. The way the C# webservice does the encryption is not compatible with the way PHP does the MD5 encryption. I have found solution for converting the C# MD5 to PHP MD5 however I can't change the C# code. Is there a way to change the way that PHP does its MD5 encryption to match C#? The c# encryption works like this:

MD5CryptoServiceProvider MD5 = new MD5CryptoServiceProvider();
byte[] bs = System.Text.Encoding.UTF8.GetBytes(stringToEncrypt);
String myString = Convert.ToBase64String(MD5.ComputeHash(bs));

MD5 Encryption Gives Wrong Encryption?

I have a registration script.At the script your password will be md5-encrypted and stored into the database.When you login the script md5-encrypts the password you type to login and checks if it is the correct one. For example I use the password: robin123
The registration md5-encrypts it as: 8dd1635ff2b8c9319526
The login-script md5-encrypts it as: 8dd1635ff2b8c931952663d4922956e7

Sha1 Implementation

I've experienced a vary strange problem working with PHP and payment gateways. If I use the sha1 function for some string I get the encrypted string, but this function output is different from the one I get using openssl on the command line of a linux machine. Ex:

inside a php I write: sha1("12345")
in the command line I type: echo 12345 ¦ openssl sha1

The output of both functions is different. However, if I store the string 12345 in a somefile.txt and I use sha1_file() function the result is the same as the standard expects, so following the previous example, when I write:

inside a php: sha1_file("somefile.txt")
in the command line I type: echo 12345 ¦ openssl sha1

The output of both functions is the same. Anybody knows if this behaviour is normal, and if it is what's it obeying to?

MD5 VS SHA1 VS AES_ENCRYPT?

I've been reading up on password encryption and I've always used MD5 but seems like its not very secure any more, so now am wondering what's better MD5 VS SHA1 VS AES_ENCRYPT?

AES_ENCRYPT seems like a secure way to encrypt passwords but being able to decrypt them seems a bit cautious. Any one any thought of the best way to encrypt passwords?

Md5 / Sha1 - Any Real Difference?

I use md5 hash with some of my cookies and occassionally a hidden form
field - I know the physical data on my network is insecure (unless being
served via https) but I was wondering if there are any advantages to using
md5 over sha1 or versa vicea... I know md5 gives me a unique 32bit hash
while sha1 I've read is 'secure' (?) and gives a 40bit hash... Since The
technical webpage on sha1 is lengthy and for the most part over my head...
and other than today, I've never heard of it before... I was wondering if
anyone could offer any comments on it...

Sha1 Column Type

I have read several online tutorials advocating storing a sha1() hashed

am running MySQL 4.1.x.
