128-bit encryption is a data/file encryption technique that uses a 128-bit key to encrypt and decrypt data or files.
It is one of the most secure encryption methods used in most modern encryption algorithms and technologies. 128-bit encryption is considered to be logically unbreakable.
128-bit encryption primarily refers to the length of the encryption or decryption key. It is considered secure because it would take massive computation and virtually thousands of years to be cracked. For example, it would take 2128 different combinations to break the encryption key, which is out of reach for even the most powerful computers.
128-bit encryption is implemented in most network/Internet communications technologies such as in web browsers and websites. The Advanced Encryption Standard (AES) is a popular encryption algorithm that supports 128-bit encryption.
Although 128-bit encryption is considered unbreakable, some computational models and theories are expected to break or compete it in years to come.
