Online MD5 Hash Generator

The .NET code I'm trying to convert to PHP is:

Dim hmac As New HMACMD5(secretPassword)Dim computedHash As Byte() = hmac.ComputeHash(stringToHash)

Currently in php I am using:

$computedHash = hash_hmac('md5', $stringToHash, $secretPassword);

From what I understand the php function hash_hmac() is the correct function to use as that is how to specify to use md5, however in testing both cases produce different hash results. I understand the .net code returns an array, however the array values are completely different than the php results.

In the .net code there is ascii encoding on the parameters but I have already verified that my php code produces the same encoding results, only the hashing produces different results. I also tested encoding results regarding leading zeroes in two digit numbers ("021" vs "21"), yes they produce different encodings but that didn't solve the hash problem when I tried both.

Example vb .net variable values:

.NET ascii encoded secretPassword "pass123" = [112, 97, 115, 115, 49, 50, 51].NET ascii encoded stringToHash "hashstring" = [104, 97, 115, 104, 115, 116, 114, 105, 110, 103] .NET hash results = [43, 65, 108, 137, 120, 163, 203, 231, 219, 197, 238, 187, 209, 216, 213, 225]

Php hash results (I already confirmed my encoding in php produces the same as .net):

The API i am using requires an MD5 encryption to work on POST requests. I am trying the make an 'userBalance' request to the API using the documentation https://www.allcoin.ca/api_market/market But every time it gives me back {'code': 1, 'msg': '签名校验失败'} (which means signature check failed). The API only asks for 2 parameteres, the api_key and sign. I carefully follow the guidance of the documentation, but the API still rejects the POST. Any suggestions why it fails the signature check? Am i missing something?

import hashlibimport keysimport requestsKEY = keys.allcoin["key"]API_SECRET = keys.allcoin["secret"]msg = "api_key='{}&secret_key={}".format(KEY, API_SECRET)signature = hashlib.md5(msg.encode("utf-8")).hexdigest()parameters = {    "api_key": KEY,    "sign": signature.upper(),}params = "&".join("{}={}".format(a, b) for a, b in parameters.items())url = "http://www.allcoin.ca/Api_User/userBalance"r = requests.post(    headers={        "Content-Type": "application/x-www-form-urlencoded",        'user-agent': 'my-app/0.0.1'    },    url=url,    params=parameters)print(r.json())

I'm trying to create a login/register system that uses MD5 hashed passwords.

So far I've managed to hash the passwords in the database however it doesn't recognise the hashed passwords when trying to login.

Probably a simple fix, any help will do :)

REGISTER JAVA

String s8 = tfPassword.getText();MessageDigest md = MessageDigest.getInstance("MD5");                        md.update(s8.getBytes());                        byte [] byteData = md.digest();                        StringBuilder sb = new StringBuilder(32);                        for (byte b : byteData) {                            sb.append(String.format("%02x", b & 0xff));                        }Statement st = con.createStatement();st.executeUpdate("insert into Login (StaffID, UName, PWord, Staff) values('"+StaffID+"','"+s7+"','"+sb+"','Yes')");

LOGIN JAVA:

String s2 = tfPassword.getText();                    MessageDigest md = MessageDigest.getInstance("MD5");                    md.update(s2.getBytes());                    byte [] byteData = md.digest();                    StringBuilder sb = new StringBuilder(32);                    for (byte b : byteData) {                        sb.append(String.format("%02x", b & 0xff));                    }                    Statement st = con.createStatement();                       // SQL Statements                     st.executeQuery("SELECT * FROM login WHERE UName= '"+s1+"' and PWord = '"+sb+"'");

<?phpinclude"db.php";if(isset($_POST['btn_upload'])){ $v1=rand(1111,9999); $v2=rand(1111,9999); $v3=$v1.$v2; $v3=md5($v3);for($i=0; $i<count($_FILES["file_img"]["name"]); $i++ ) {  //select folder id to insert all images   $folder_name=$_POST['select_folder_name'];    $filename=$_FILES["file_img"]["name"][$i];    $filetype=$_FILES["file_img"]["type"][$i];    $gallery_image_dst="./gallery_image/".$v3.$filename;    $gallery_image_location="gallery_image/".$v3.$filename;    move_uploaded_file($_FILES["file_img"]["tmp_name"],$gallery_image_dst);  //insert image name, path, type and folder name to database.  $insert_gallery= "INSERT INTO `gallery`(`image_name`, `image_path`,   `image_type`,`folder_name`) VALUES   ('$filename','$gallery_image_location','$filetype','$folder_name')";   $result=mysqli_query($conn, $insert_gallery);            if($result){        echo"<script>alert('Successfully uploaded')</script>";        echo"<script>window.open('index.php?upload_images','_self')         </script>";   }else{       echo"<script>alert('Oop! Somthing going wrong')</script>";   }    }  }?>

Here I am getting all image location, image type, and image md5 name in my database. But problem is that I'm not getting any images to my gallery_image folder. After Successfully uploaded message I'm getting a error Warning:move_upload_file() expects parameter 1 to be string, array given in c"\xampp........location and line no.

We have a CS Cart and a Magento 2 website and now we want to migrate all customers from CS Cart store to Magento 2. Rest of the things are fine for us but password is the problem. We want to migrate password also from CS Cart to Magento 2 so that user can login to this new Magento site with same credentials which they were using in CS Cart.

But because both systems use their own hashing method (CS Cart uses MD5 with some salt sufix) so direct migration of password hash does not work.

How we can migrate all user accounts from CS Cart to Magento 2 with passwords?
