In this article, we are going to learn what is JavaScript AES Encryption. AES is an algorithm developed for the encryption of data. AES uses the same key to encrypt and decrypt data, called the symmetric encryption algorithm. AES encryption is Advanced Encryption Standard (AES) to encrypt the data in the application. We use the JavaScript library Forge to perform AES encryption. These algorithms are used in different communication apps such as WhatsApp, Signal, etc. The third-party user cannot be able to decrypt the message, and when the message is reached the destination receiver endpoint, it is decrypted using the ...
