The Advanced Encryption Standard (AES) is a National Institute of Standards and Technology specification for the encryption of electronic data.
How secure is AES? The general consensus is that it is the most secure encryption algorithm available. AES has been subjected to more scrutiny than any other encryption algorithm to date. On both a theoretical and practical basis, AES is considered "secure" in the sense that the only effective way to crack it is through a brute-force generation of all possible keys. With a key size of 256 bits, no known brute-force attack can break AES in a reasonable amount of time (it would take years even on the fastest systems available).
In cryptography, the Advanced Encryption Standard (AES) is an encryption standard adopted by the U.S. government. The AES ciphers have been analyzed extensively and are now used worldwide.
AES was announced by National Institute of Standards and Technology (NIST) as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001 after a 5-year standardization process in which fifteen competing designs were presented and evaluated before Rijndael was selected as the most suitable (see Advanced Encryption Standard process for more details). It became effective as a Federal government standard on May 26, 2002 after approval by the Secretary of Commerce. It is available in many different encryption packages. AES is the first publicly accessible and open cipher approved by the NSA for top secret information.

All iMacros versions use AES encryption. It is controlled via the !ENCRYPTION command.
