AES 256

AES 256, short for Advanced Encryption Standard with a key length of 256 bits, is a widely used symmetric encryption algorithm. It employs a substitution-permutation network to ensure data confidentiality and security. AES comes in different key lengths, including AES-128 and AES-192, where the numbers represent the key size in bits. AES-128 uses a 128-bit key, while AES-192 uses a 192-bit key. These standards are considered secure and are used for various applications to protect sensitive information during data transmission and storage.
