256-bit AES encryption (Advance Encryption Standard) is an International standard which ensures data is encrypted/decrypted following this approved standard. It ensures high security and is adopted by the U.S. government and other intelligence organizations across the world.

Online Tool for AES Encryption and Decryption Advanced Encryption Standard(AES) is a symmetric encryption algorithm. AES is the industry standard as of now as it allows 128 bit, 192 bit and 256 bit encryption.Symmetric encryption is very fast as compared to asymmetric encryption and are used in systems such as database system. What is the difference between AES-128 and AES-256? And AES - Advanced Encryption Standard, is a symmetric key (same key) algorithm. This block cipher algorithm (large data is divided and processed in blocks) has it's strength in it's keyed permutation. The bigger the key size more are the permutations

How Secure Is 256-bit Encryption? - DZone Security As it is would require at least 3*10^51 years to exhaust all the combinations possible by the 256-bit encryption technique. So, how secure is your data when utilizing 256-bit encryption.

### AES uses a symmetric algorithm, which means the same key is applied for both encryption and decryption. The algorithm provides 128-bit block encryption and has been designed to supports key sizes of 128, 192 and 256 bits. AES 256-bit encryption is the strongest and most robust encryption standard that is commercially available today.

256 bits is a common key size for symmetric ciphers in cryptography, such as Advanced Encryption Standard. Modern GPU chips move data across a 256 - bit memory bus. 256 - bit processors could be used for addressing directly up to 2 256 bytes.
