AES, which stands for Advanced Encryption Standard is a cryptographic cipher that refers to the process of concealing electronic data with a block length of 128-bit and key lengths of 128, 192 or 256-bit symmetric algorithm.
Since Roman times, security has been essential in keeping communications between parties private and secure. In today's digital world, security has become paramount as it forms the backbone of online security. The AES cipher is the most widely used standard and you might not even be aware that you are using it. For example, when you fill out forms online for the government (passport applications, drivers license renews, etc.), when you store personal information on a website (Facebook, Twitter, etc.), and even when you use your VISA or bank card to make an online transaction, it is in the background, doing its thing.
Advanced Encryption Standard (AES) was originally known as Rijndael, a combination of the names of the Belgian developers who created it.
