AES conventions

AES (Advanced Encryption Standard) is a secure method for protecting digital data. It uses a secret key to scramble information into an unreadable form, called ciphertext, which can only be decrypted back into the original data with the same key. AES operates on fixed-size data blocks (128 bits) and applies multiple rounds of transformation, enhancing security. It supports key lengths of 128, 192, or 256 bits, with longer keys providing stronger protection. AES is widely used in secure communications, banking, and data storage due to its efficiency and robustness against attacks.
