The design and strength of all cryptography key lengths of the AES algorithm i.e., 128, 192 and 256 are sufficient to protect work up to the Secret level. Top Secret information will require the use of either the 192 or 256 cryptography key lengths. This is an execution of AES in produ...

A commonly used algorithm today for symmetric cryptography is AES, which means "Advanced Encryption Standard". 1 AES (Symmetric crypto) This algorithm has a combination of substitutions and transpositions using a key of fixed length. A key of fixed length means that the algorithm can only have ...
DES served as the linchpin of government cryptography for years until 1999, when researchers broke the algorithm's 56-bit key using a distributed computer system. In 2000, the U.S. government chose to use AES to protect classified information. DES is still used in some instances for backward...

Two scripts in Python to encrypt/decrypt using the 128 bits AES algorithm, ECB mode with hex "00" as padding for each character. For the encryption, an ascii plaintext file is taken as the input, then an encrypted hex file is outputted. For the decryption, a ciphertext hex file is ta...
In addition to security, there are other key advantages to using the AES algorithm. For example, by offering three levels of encryption – AES-128, 192, or 256 – developers can balance security with usability and performance. As previously mentioned, with today's computers, even AES-128 encr...
