I want upload a file with evaporate.js and crypto-js using x-amz-security-token:...

You have your crypto.HmacSHA256 parameters reversed. They should all be the other way around. I've been bashing my head against a wall trying to get evaporate 2.x to work for the last week, it's been very frustrating.
I tried your code above and looked over all the docs and forum posts related to this, and I think using Cognito for this auth just doesn't work or isn't obvious how it's supposed to work, even though the AWS docs suggest it's possible.
In the end I went with using Lambda authentication and finally got it working after seeing much misinformation about how to use various crypto libraries to sign this stuff. I got it working last night after rigorously examining every bit of what was going on. Reading the docs also helped get me on the right path as to how the crypto needs to work, it gives example inputs and outputs so you can test for sure that your crypto methods are working as AWS expects them to work:
Tasks 1, 2 and 3 are especially important to read and understand.
Based on the example provided here on how to establish a shared secret and derived key between JS (Crypto-JS) and Python, I can end up with the same shared secret and derived key on both ends.
However, when I try to encrypt as below, I cannot find a way to properly decrypt from Python. My understanding is that probably I am messing with the padding or salts and hashes....

The issue is that the key is not passed correctly in the CryptoJS code.
The posted Python code generates
LefjQ2pEXmiy/nNZvEJ43i8hJuaAnzbA1Cbn1hOuAgA= as Base64-encoded key. This must be imported in the CryptoJS code using the Base64 encoder:
After upgrading to Angular 13 the application no longer works during runtime. From what I've read NODE_DEBUG is Webpack specific and for some reason is not recognized when running the application with an 'ng serve'. I've also recently upgraded to macOS Monterey. I've very stuck at the moment....

Try to delete your node_modules folder and run npm install again.
If still not working try to downgrade the node version to 12.20.x and check.
After upgrading my Angular from 12.0.2 to 13.0.3 everything was working fine. I was trying to remove some packages that was not used such as
jquery, and some other i do not remember etc. and after that I deleted
package-lock.json and run
npm i to installed all packages again. After that I recieved bunch of errors which then i again reverted package.json and tried npm i then I am getting below errors. And I am unable to fixed it.
Any idea how can i resolve this ?...

As I researched a lot and did not find a solution to this issue as it's occurring only on the newer version of the animation package.
I tried the below versions:
13.2.4 (Latest one) throwing same es error
13.2.3 throwing same es error
13.2.2 throwing same es error
13.2.1 throwing same es error
13.2.0 working without error.
So I think for a temporary fix you should update your
package.json by pointing to a specific version of this
npm like below.
I have this code to hash an object.
I am saving this hash as a key in redis with a timeout but even if I change something in that incoming request object it is generating the same hash and redis shows there is same key already there.
Does this package have some trouble on hashing or does my code have any problem?...
ANSWERAnswered 2022-Feb-15 at 10:02
You can't pass an Object to the SHA256 Method, you may only pass strings and WordArrays.
When you pass an object, cryptojs will run
.toString() on it, which will always give the same output (
[object Object]), and thus the same hash.
But I have to do this through PHP.
ANSWERAnswered 2022-Feb-15 at 16:16
This is due to the different padding. CryptoJS uses PKCS#7, mcrypt applies zero padding.
You should replace mcrypt on the PHP side as it is deprecated (s. here). An alternative would be PHP/OpenSSL, which uses PKCS#7 by default.
A solution with PHP/OpenSSL which produces the same ciphertext is:

The CryptoJS code is incomaptible because the IV is decoded incorrectly. Instead of the Hex encoder, the Utf8 encoder must be used.
Also, the encrypt library applies the CTR mode by default. Therefore, in the CryptoJS code the CTR mode must be used instead of the CBC mode:
I am creating a e-commerce website with MERN stack but i cannot register a new user. It only registers the first user when I clear the database but after that it shows an error code. Here is the code: The user Schema:...
ANSWERAnswered 2022-Feb-02 at 15:40
so i think you might previously have had "name" as a required field in your UserSchema definition. therefore it is still expecting every user to have a "name" field and value which explains the error. clearing/syncing indexes should sort it. you can manually dro indexes in mongodb for that specific collection or use mongoose to sync the indexes as seen here.
just seen that OP solved the issue by deleting the database... while this for sure fixes it, it's drastic. i'm certain the error was caused by a missing required field. so if the situation comes up again, just removing indexes will be all the help you need, avoiding dropping other collections that aren't affected by the index.
I am working out a custom hybrid encryption system. I've got symmetric encryption & asymmetric encryption & decryption all handled server-side. All I need to work out now is symmetric decryption.
I got some trouble because my client is sending symmetric key, iv & data all in string format (after asymmetric decryption), but CryptoJS is very touchy with it's encoding. It's also very confusing and vague as far as documentation goes- at least for a relatively new developer. I just can't figure out what encoding CryptoJS wants for each argument. I figure I should have guessed right by now, but no.
I'm requesting help getting the encoding right so that I can decrypt with the following. And thanks a lot for any assistance.
Example of data after asymmetric decryption as per below (throw away keys):...
ANSWERAnswered 2022-Jan-31 at 08:43
- You are using the wrong encoders for data, key and IV. All three are Base64 encoded (and not hex or Utf8). So apply the Base64 encoder.
- The ciphertext must be passed to
CipherParamsobject or alternatively Base64 encoded, which is implicitly converted to a

ANSWERAnswered 2022-Jan-26 at 09:46
jsonwebtoken is a Node.js module, your previous use of it in a react application relied upon a polyfill of the Node.js std modules. This most likely a) relied on slow js cryptography that isn't maintained anymore and lacks feature parity with Node's crypto and b) increased your js bundle size considerably. Updating react likely meant updating webpack which no longer defaults to using the questionable crypto polyfill.
