SHA256 online Hash Generator

I need to get the digest of an uploaded file in my AngularJS app, but the result digest is different from the file digest I get with bash.

I started using jshashes, but when I saw that the resultant hash (on the web app) was different from the one which I get locally using bash I decided to move to CryptoJS. But the result is the same,the hash from the uploaded file is still different.

Here's my code:

var reader = new FileReader();    reader.readAsBinaryString(controller.file);controller.fileHash = CryptoJS.SHA256(reader.result).toString(CryptoJS.enc.Hex);

As you can see the code is quite simple, just reads the uploaded file from the variable using FileReader and convert the value into a BinaryString, hash the content and finally assign the result to another controller valriable to show it in the html.

In my shell (local environment) to get the file digest I run the following command:

$ shasum -a 256 [path/to/file]

In order to upload files, i'm using ng-file-upload

What I'm missing? If anyone can help me or guide me to see the solution I will be very greatful.

Thank you in advance.

Update 1:As @destroyer said in the comments below readAsBinaryString is deprecated and it's an asynchronous method, so here's my actual code:

var reader = new FileReader();reader.onload = function() {    controller.fileHash = CryptoJS.SHA256(reader.result).toString(CryptoJS.enc.Hex);};reader.readAsArrayBuffer(controller.file);

I tried this solution in order to convert the ArrayBuffer object into a BinaryString. But the result is still wrong.

Update 2: Here's an image of a console log og the object I want to hash

I'm porting some Java code to PHP code. In Java I have a hash SHA256 code as below:

public static String hashSHA256(String input)        throws NoSuchAlgorithmException {    MessageDigest mDigest = MessageDigest.getInstance("SHA-256");byte[] shaByteArr = mDigest.digest(input.getBytes(Charset.forName("UTF-8")));    StringBuilder hexStrBuilder = new StringBuilder();    for (int i = 0; i < shaByteArr.length; i++) {        hexStrBuilder.append(Integer.toHexString(0xFF & shaByteArr[i]));    }    return hexStrBuilder.toString();}

In PHP, I hash as below:

$hash = hash("sha256", utf8_encode($input));

I run the sample code with both input = "test". However, I got 2 hash strings which are not the same:

Java: 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2bb822cd15d6c15b0f0a8PHP: 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08

Can someone explain to me why and how to get them match each other? Please note that I cannot modify the Java implementation code, only to modify PHP.

Really appreciate!

I want to get sha2 hash of particular java object. I don't want it to be int, I want byte[] or at least String. I've got the following code to create sha2:

static byte[] sha2(byte[] message) {    if (message == null || message.length == 0) {        throw new IllegalArgumentException("message is null");    }    try {        MessageDigest sha256 = MessageDigest.getInstance(SHA_256);        return sha256.digest(message);    } catch (NoSuchAlgorithmException e) {        throw new IllegalArgumentException(e);    }}

I can just convert my object to byte[], but I don't think it's a good idea to store big array in memory just to create 32 byte array. So how can I compute sha2(or maybe another crypto hash function) of object?

I need to write some code to work in bash that emulates the HMAC generator found here:

https://www.freeformatter.com/hmac-generator.html#ad-output

So far, I have this (NOTE: these are not real passwords or salt values so I have no problems using them here. The 'key.txt' file just contains the 'key' variable value):

key="123456781000000003PASSWORDLOGIN"salt1="99992423A9495A45-8826-44AC-999C-219EFB13EB1A99992423"echo -n "$salt1" | xxd -p -c 256 > hex1.hexhexKey=`cat hex1.hex`openssl dgst -sha256 -mac HMAC -macopt hexkey:$hexKey key.txt

My output is this:

fb1133ec9066ad3b5a487893febd2b2d803914ebac2ee6e6a9c587d7219cda65

...but on that freeformatter site, I get this:

Any ideas what I am doing wrong?

I am following this tutorial to sign data with SHA-256withECDSA.

Using the same private key and message, it generated different signature result every time. The only change I made is return Base64 encoded string instead of Base58

Is it supposed to be the same signature every time?

public static string GetSignature(string privateKey, string message){    var curve = SecNamedCurves.GetByName("secp256k1");    var domain = new ECDomainParameters(curve.Curve, curve.G, curve.N, curve.H);    var keyParameters = new            BC.Crypto.Parameters.ECPrivateKeyParameters(new BC.Math.BigInteger(privateKey),            domain);    ISigner signer = SignerUtilities.GetSigner("SHA-256withECDSA");    signer.Init(true, keyParameters);    signer.BlockUpdate(Encoding.ASCII.GetBytes(message), 0, Encoding.ASCII.GetBytes(message).Length);    var signature = signer.GenerateSignature();    return Convert.ToBase64String(signature);}
