آنلاین SHA512 ژنراتور هش

I have an input element with type of file and I want to calculate the selected file sha512

I already use FileReader and Crypto-js library like this:

// find ElementRef of input element from DOMconst file = t.el.nativeElement.querySelector('#fileForUpload');// get list of selected filesconst fileList: FileList = file.files;// get selected fileconst f: File = fileList[0];// create an instance of FileReaderconst reader = new FileReader();// set onload eventreader.onload = (e) => {    // print the sha hash in the console     console.log(crypto.SHA512(reader.result));};// call FileReader and pass our file to itreader.readAsBinaryString(f);

but this way is too slow, not cover all file types and has the size limit (I tested it with a 1GB file and my ram became almost full)

so is there any library or solution for this?

Heys guys,

I'm struggling about out to decrypt the hash how my sha512 encryption. I'm searching a way to finnaly decrypt it.

By the way this is how I do the encryption:

Dim uEncode As New UTF8Encoding()        Dim bytClearString() As Byte = uEncode.GetBytes("to encrypt")        Dim sha As New  _        System.Security.Cryptography.SHA512Managed        Dim WordEncrypt As String = ""        Dim hash() As Byte = sha.ComputeHash(bytClearString)        For Each b As Byte In hash            WordEncrypt &= b.ToString("x2")        Next

What i need now is to know how to decrypt it.

A common practice to compare two text file is to use the SHA-512 [or any other realted SHA algo]. If two SHA results are not the same then the files are not exactely the same.

I would like to do the same with two SQL queries. I just want to know if the queries gives 100% identical result or not with a SHA-512 [or sha-256 would be OK as well]?

Is that possible to perform that? I am using SQL Server...

I need code for a console application that will encrypt numbers from 0 to 999,999 in sha512. Or just code to encrypt the number in sha512 in the C#. Please help me)

OK So I have 2 scripts. One to register users and one for someone to login. I am new to PHP and was on here earlier and it was said to me that I should not use MD5. So here is my attempt to do things the right way and to practice good coding habits from the beginning.

So far I can get the password hashed and in to the database but when I try to login it tells me invalid password. Here is the code I have so far. (PLEASE REMEMBER THAT I AM NEW AND I REALLY AM HAVING A HARD TIME UNDERSTANDING THIS).

This is the Login (I only included the main part of the login where I am having trouble.)

     $username = mysqli_real_escape_string($con,$username);     $password = stripslashes($_REQUEST['password']);     $password = mysqli_real_escape_string($con,$password);     $password = hash('sha512',$password);     //Checking is user existing in the database or not     $query = "SELECT * FROM `users` WHERE username='$username'     AND password='".$password."'";     $result = mysqli_query($con,$query) or die(mysql_error());     $rows = mysqli_num_rows($result);     $row = mysqli_fetch_array($result);     if($rows==1){

This is the Registration (I only included the main part of this also)

//Strip & Escape PW$password = stripslashes($_REQUEST['password']);$password = mysqli_real_escape_string($con,$password);$sql_u = "SELECT username FROM users WHERE username='$username'";$sql_e = "SELECT email FROM users WHERE email='$email'";$res_u = mysqli_query($con, $sql_u);$res_e = mysqli_query($con, $sql_e);if (mysqli_num_rows($res_u) > 0) {$name_error = "Sorry... username already taken";}else if(mysqli_num_rows($res_e) > 0){$email_error = "Sorry... email already taken";}else{$query = "INSERT INTO users (username, email, password)VALUES ('$username', '$email', '".hash('sha512',$password)."')";$results = mysqli_query($con, $query);echo 'You Have Registered Successfully!<br>

BTW I looked at this article already and am completely lost. So if you are gonna flag this as duplicate base on this article can you please let me know what I am missing as I do not understand this article at all. Thank you.

Verify a SHA512 password if($row['password']==hash('SHA512', $upass))
