Encryption in vb and encrypt in javascript.

yeoyl — Thu, 12 May 2016 21:37:29 +0800

First i encrypt by using vb and folo by javascript.
The result is not the same.
HELP !!!!

Private Function Encrypt(ByVal strText As String, ByVal encKey As String) As String

Dim byKey() As Byte
Dim IV() As Byte

Try

byKey = System.Text.Encoding.UTF8.GetBytes(encKey)
IV = System.Text.Encoding.UTF8.GetBytes(encKey)

Dim des As New DESCryptoServiceProvider()
Dim inputByteArray() As Byte = Encoding.UTF8.GetBytes(strText)
Dim ms As New MemoryStream()
Dim cs As New CryptoStream(ms, des.CreateEncryptor(byKey, IV), CryptoStreamMode.Write)

cs.Write(inputByteArray, 0, inputByteArray.Length)
cs.FlushFinalBlock()

Console.WriteLine(des.Mode.ToString)
Console.WriteLine(des.Padding.ToString)
Console.WriteLine(Convert.ToBase64String(ms.ToArray()))

Return Convert.ToBase64String(ms.ToArray())

Catch ex As Exception
Console.Write(ex.Message, "Error")
Return ""
End Try

End Function

Encrypt with javascript.
function encryptByDES(message, key) {

var msgbytes = [];

for (var i = 0; i < message.length; ++i) {
msgbytes.push(message.charCodeAt(i));

}
var orimessage = msgbytes.join("");

var keybytes = [];

for (var i = 0; i < key.length; ++i) {
keybytes.push(key.charCodeAt(i));
}
var orikey = keybytes.join("");

var keyHex = CryptoJS.enc.Utf8.parse(orikey);

var iv = keyHex

var encrypted = CryptoJS.DES.encrypt(orimessage, keyHex, {
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.Pkcs7,
iv:iv

});

document.writeln('encrypted.toString() -> base64(ciphertext) :', encrypted.toString());
document.writeln('base64(ciphertext) <- encrypted.toString():', encrypted.ciphertext.toString(CryptoJS.enc.Base64));
document.writeln('ciphertext.toString() -> ciphertext hex :', encrypted.ciphertext.toString());
return encrypted.toString();
}

makes life/job easier as simple as abc
