用于计算给定任何AES-128循环密钥的Rijndael密钥计划的工具。
aeskeyschedule的Python项目详细描述
AES密钥计划工具
此工具可以用作python库或命令行工具
此项目在pypi上可用
pip3 install aeskeyschedule --user --upgrade
命令行工具
usage: aeskeyschedule [-h] [-r AES_ROUND] round_key
Tool to calculate the Rijndael key schedule given any AES-128 round key.
positional arguments:
round_key the round key in hex notation from which the full key
will be derived.
optional arguments:
-h, --help show this help message and exit
-r AES_ROUND, --round AES_ROUND
The AES round of the provided key. Defaults to 0 (base
key).
示例用法

python库
两个主要功能是key_schedule和reverse_key_schedule
计算AES-128基本密钥，给出最后一轮密钥：
base_key=reverse_key_schedule(b'\xe2K\xbb"~\xe8\xb3\xe6u\x06_\xdb\x9b\xd6\x9bB',10)
使用AES-128基本密钥计算最后一轮密钥：
base_key=b'\x91\xa3\xba\x04\xe3\xdb:\x10\xc7$R\x15|]\xca\x87'expanded_key=key_schedule(base_key)assertexpanded_key[0]==base_keylast_round_key=expanded_key[10]
