aes encryption and decryption in javascript example

aes (advanced encryption standard) is a symmetric encryption algorithm commonly used to encrypt and decrypt data securely. in javascript, you can use the `crypto` module provided by the web crypto api to perform aes encryption and decryption.

here is a step-by-step tutorial on how to implement aes encryption and decryption in javascript:

1. generate an aes key and an initialization vector (iv):

2. encrypt a plaintext using the aes key and iv:

3. decrypt the ciphertext using the aes key and iv:

4. putting it all together:

in this example, we first generate an aes key and an iv. then, we encrypt a plaintext using the key and iv, and finally decrypt the ciphertext back to the original plaintext. make sure to handle errors and exceptions appropriately when implementing aes encryption and decryption in your javascript application.
