AES (Advanced Encryption Standard) is the gold standard of data encryption, with three main cypher key sizes – 128-, 192-, and 256-bit. There is no record of AES encryption ever being broken, and a brute-force attempt to crack this encryption algorithm would take theoretically billions of years. It is used by all kinds of security experts, governments, militaries, and other top-security agencies like the NSA to protect highly sensitive data.
