AES

AES round key calculation, Stark implement with python

reverseKey can

• print all round keys from the AES key;
• print all round keys from any intermediate or final round key(s).

Usage:

python reverseKey.py AES_key_in_hex
python reverseKey.py Round_key(s)_in_hex Initial_round_key_number_between_0_and_10#11#13

The AES key size is deduced from the size of the parameter, so

• for AES-128, provide one round key and its index
• for AES-192, provide one round key concatenated with the first half of the next round key and the index of the starting round key
• for AES-256, provide two concatenated round keys and the index of the starting round key

Examples:

• AES-128: (provide 1 round key)

python reverseKey.py FAEF63792F9A97A1FB78C88C4CA7048F 10

• AES-192: (provide 1.5 round keys)

AES

AES 轮密钥计算, Stark 的 python 版本

reverseKey 功能

• 通过当前 AES 密钥输出所有轮密钥；
• 通过任意一轮密钥输出所有轮密钥；

用法:

python reverseKey.py AES_key_in_hex
python reverseKey.py Round_key(s)_in_hex Initial_round_key_number_between_0_and_10#11#13

AES密钥长度是通过参数的长度来决定的

• 对于 AES-128，提供 1 轮秘钥及其轮次
• 对于 AES-192，提供 1.5 轮秘钥及其轮次
• 对于 AES-256，提供 2 轮秘钥及其轮次

举例:

• AES-128: (提供1轮密钥)

python reverseKey.py B1BA2737C83233FE7F7A7DF0FBB01D4A
python reverseKey.py 97F926D5677B324AC439D77C8B03FDF8 5
python reverseKey.py FAEF63792F9A97A1FB78C88C4CA7048F 10

• AES-192: (提供1.5轮密钥)
