SHA512 is not the same in CryptoJS and closure
I have some problems with a simple crypto option.
I want to do the following:
- getting url encoded and base64 encoded value
- make url-decoding
- do base64 decoding
- hash with Sha512
When working with CryptoJS, I use the following code:
var parameter = "Akuwnm2318kwioasdjlnmn";
var urlDecoded = decodeURIComponent(parameter);
var base64Decoded = CryptoJS.enc.Base64.parse(urlDecoded);
var hashed = CryptoJS.SHA512(base64Decoded).toString(CryptoJS.enc.Base64);
//hashed = "UxupkI5+dkhUorQ+K3+Tqct1WNUkj3I6N76g82CbNQ0EAH/nWjqi9CW5Qec1vq/qakNIYeXeqiAPOVAVkzf9mA=="/eWTS2lUgCEe6NJDXhNfYvXMRQDvH6k2PHVmy6LJS7RloVvcQcpVjRNVU5lJpAg=="
When working with Closure, I use the following code:
var parameter = "Akuwnm2318kwioasdjlnmn";
var urlDecoded = decodeURIComponent(parameter);
var byteArray = goog.crypt.base64.decodeStringToByteArray(urlDecoded);
var base64Decoded = goog.crypt.byteArrayToHex(byteArray);
var sha512 = new goog.crypt.Sha512();
sha512.update(base64Decoded);
var hashed = sha512.digest();
hashed = goog.crypt.byteArrayToHex(hashed);
//hashed = "bc2a878edfffb0937fbc6c0f9dbc9566edc59b74080d68d4c8bdfeb4027f17c4316a02285baaf446872d2df37b1144ac3ce18d62ab9c786b1f1fb18a53acea1d"
So why are different hashes?
I would be very happy if someone could tell me how to adapt Closure-Code to get the same hash as the CryptoJS code.
Thank you so much!
PS:
I've also tried:
var parameter = "Akuwnm2318kwioasdjlnmn";
var urlDecoded = decodeURIComponent(parameter);
var base64DecodedByteArray = goog.crypt.base64.decodeStringToByteArray(urlDecoded);
var sha512 = new goog.crypt.Sha512();
sha512.update(base64DecodedByteArray);
var hashed = sha512.digest();
hashed = goog.crypt.byteArrayToHex(hashed);
//hashed = "531ba9908e7e764854a2b43e2b7f93a9cb7558d5248f723a37bea0f3609b350d04007fe75a3aa2f425b941e735beafea6a434861e5deaa200f3950159337fd98"
but then as you can see I get another hash. why??

The first hash value is identical to the third, except that it is base64 encoded and not hexadecimal. You can change the hex encoding and get the same value:
var hashed = CryptoJS.SHA512(base64Decoded).toString(CryptoJS.enc.Hex);
//hashed = "531ba9908e7e764854a2b43e2b7f93a9cb7558d5248f723a37bea0f3609b350d04007fe75a3aa2f425b941e735beafea6a434861e5deaa200f3950159337fd98"
The second approach you show has a different meaning because you are not storing the same data; you convert the byteArray to a hex string instead and then hash that string representation, not the underlying values.
