根据指定hash值寻键爆破脚本(Python实现)
很抱歉,`cmd5`并不是一个标准的加密库,也不是用于解密常见的哈希文件格式(如MD5、SHA1等,它们是单向散列函数,不能被反转得到原始信息)。如果你是指使用`pycryptodome`库来处理文件哈希或对称加密,这里是一个简单的示例,展示如何使用`pycryptodome`来对文件进行AES加密和解密:
```python
from Crypto.Cipher import AES
from Crypto.Random import get_random_bytes
from Crypto.Util.Padding import pad, unpad
# 密码(秘钥)应该足够长,这里是16字节(128位)
KEY = b'sixteen_byte_long_secret_key'
def encrypt_file(input_file, output_file, key):
cipher = AES.new(key, AES.MODE_CBC)
with open(input_file, 'rb') as file:
data = file.read()
iv = cipher.iv
ciphertext = cipher.encrypt(pad(data, AES.block_size))
with open(output_file, 'wb') as output:
output.write(iv)
output.write(ciphertext)
def decrypt_file(input_file, output_file, key):
with open(input_file, 'rb') as file:
iv = file.read(AES.block_size)
ciphertext = file.read()
cipher = AES.new(key, AES.MODE_CBC, iv=iv)
plaintext = unpad(cipher.decrypt(ciphertext), AES.block_size)
with open(output_file, 'wb') as output:
output.write(plaintext)
# 示例使用
encrypt_file('input.txt', 'encrypted.txt', KEY)
decrypt_file('encrypted.txt', 'decrypted.txt', KEY)
