What is AES Encryption?

AES, or Advanced Encryption Standard, is a globally recognized encryption method that protects sensitive data from unauthorized access. Designed to be secure against brute-force attacks, AES has become the benchmark for data encryption in various industries, including finance and government. It works by transforming plaintext into ciphertext using a specific key, making the original data unreadable to anyone without the correct key. The AES-256 variant is particularly noted for its high level of security, making it virtually impossible to crack with current technology.
