  Hi Sir, Small doubt, Key and iv is mentioned "8080808080808080" in javascript. After run a page, if anyone go to browser and click "Source", they can easily know the key and iv right? then can decrypt using this right? then there is no security right? please suggest

  I have changed the "8080808080808080" to "7676876876786234" but encrypt string of same input value is same .. Here no any sense of use key because after change of key ... Same output. I am not like this process

    Ohh replace 8080808080808080 with 128-bit string .generate 128 bit string here https://www.allkeysgenerator.com/Random/Security-Encryption-Key-Generator.aspx

  Whats the use encryption on client side, we can decrypt this password in client side because we know encryption logic and keys.

  Very helpful for understanding the implementation of AES with client side and access with server side.

  I Have this JS file that encypts how to decrypt in C# -------------- function encrypt(text) { var hexKey = 'E8E9277F7A2696F29EDAAE6EC29F659F'; var key = aesjs.utils.hex.toBytes(hexKey); while ((text.length % 32) !== 0) { text += ' '; } var textBytes = aesjs.utils.utf8.toBytes(text); var aesEcb = new aesjs.ModeOfOperation.ecb(key); var encryptedBytes = aesEcb.encrypt(textBytes); // To print or store the binary data, you may convert it to hex var encryptedHex = aesjs.utils.hex.fromBytes(encryptedBytes); return encryptedHex }

  saikumar Godalu9y agoPosted Jun 7, 2017, 2:27 PM

  To Decrypt on client side : var decryptedData = CryptoJS.AES.decrypt(encrypted, key, { keySize: 128 / 8, iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 } ); console.log('Original Text : '+decryptedData.toString(CryptoJS.enc.Utf8)) // outputs "Hello world"
• SG

  saikumar Godalu9y agoPosted Jun 7, 2017, 2:26 PM

  To Encrypt in C# : AESEncrytDecry.EncryptStringAES("Hello world");
