ERROR in src/app/components/dashboard/dashboard.component.html:1:1 - error NG8001: 'StackLayout' is ot a known element:
- If 'StackLayout' is an Angular component, then verify that it is part of this module.
- To allow any element add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component.

So im trying to decrypt a string I cryptographed with JS in Python. I used the aes-js
library. I get this: caba6777379a00d12dcd0447015cd4dbcba649857866072d

QUESTION
I have a given encryption in javascript using aes-js and need to decrypt it in Java. The result is not the expected text, but some gibberish. I suspect that I have a wrong understanding of the initialization vector and the counter. I tried multiple iv, such as only 0, only 1, 1 to 16, 5 to 20 and 5 to 15 then 0 to 4.
This is the code I try to translate into java. It works fine.
...ANSWER
Answered 2020-Mar-01 at 10:23To give this thread an accepted answer:
Topaco is right. The correct iv is byte[] iv = new byte[] {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 5};
QUESTION
When I do AES-256 CTR encryption in C using tiny-AES-c library (https://github.com/kokke/tiny-AES-c) I unable to decrypt it properly in JavaScript. For JavaScript decryption I'm using library https://github.com/ricmoo/aes-js
After encryption I do base 64 encode and before decryption base 64 decode and that part works fine.
In fields below you can see my C and JavaScript code:

QUESTION
I have been unable to get existing legacy code in Python to encrypt/decrypt the same as NodeJS. I do get the first 16 characters correctly decoded.
Here is the Python code:
...ANSWER
Answered 2020-Jan-04 at 17:24Essential for the CTR mode is the incrementation of the counter, which is why this mode is actually called counter mode [1]. Since in the Python code the counter is a constant, i.e. not incremented at all, this code implements the CTR mode at most formally, but certainly not functionally and is also negligently insecure [2][3].
Most libraries will try to prevent such a misuse of the CTR mode. Therefore it is very unlikely to find a library in NodeJS (or any other language) that makes this intentionally possible.
Nevertheless, decryption in NodeJS (or any other language) is relatively easy to achieve by manually implementing the mode: In the CTR mode, a byte sequence is generated from the IV, starting with the initial IV, by appending the corresponding incremented IV for each block. The sequence generated in this way is then encrypted with AES and the result is XOR-ed with the plaintext / ciphertext [1]. This scheme applies to both encryption and decryption. Since the Python code doesn't perform any incrementation, this step must simply be skipped, e.g.:
