What does 128 bit aes encryption mean?

128-bit AES encryption refers to the Advanced Encryption Standard (AES) that uses a key size of 128 bits for encrypting data. This means that there are 2^128 possible keys, making it extremely secure and resistant to brute-force attacks. AES operates on blocks of data, typically 128 bits in size, and is widely used for securing sensitive information in various applications, including data storage and communications. Overall, 128-bit AES is considered a strong encryption standard for protecting data confidentiality.
