how get image md5 hash from image buffer in the browser in javascript

To get the MD5 hash of an image in the browser using JavaScript, you can use the CryptoJS library. First, you need to convert the image buffer to a Base64-encoded string. Then you can use the CryptoJS.MD5() method to calculate the MD5 hash of the Base64-encoded string.

Here's an example code snippet:


index.tsx
// assume that you have an image buffer called "imageBuffer"

// convert the image buffer to a Base64-encoded string
var binary = '';
var bytes = new Uint8Array(imageBuffer);
var len = bytes.byteLength;
for (var i = 0; i < len; i++) {
    binary += String.fromCharCode(bytes[i]);
}
var base64 = window.btoa(binary);

// calculate the MD5 hash of the Base64-encoded string using CryptoJS
var md5 = CryptoJS.MD5(base64).toString();
