An algorithm that makes data secure through encryption and only readable by authorized parties. Here’s an oversimplified example of encryption. You save a file in the cloud with text that says, “THIS IS SENSITIVE DATA”. That text is then encrypted into what is called ciphertext and will appear to anyone else who accesses it as ‘a8hs0x1411h0Yudi’ unless they have the encryption key.
AES is one of many forms of encryption including DES, RSA, and more. The reason for AES’ prominence is because it has been standardized by the U.S. Government and National Institute of Technology. You may see different numbers like 128-bit or 256-bit following AES. These are different key sizes. The larger the number, the larger the key, and the stronger the encryption.« Back to Glossary Index
