在日常的工作学习当中,我们总会遇到各式各样的问题,其中不少的问题都是一遍又一遍简单重复的操作,不妨直接用Python脚本来自动化处理,帮助我们减少无谓的时间浪费,提高工作学习中的效率。

对文件内容进行加密
有时候手中文件的内容十分的重要,可以选择对此进行加密,代码如下

| from cryptography.fernet import Fernet
def encrypt(filename, key):
fernet = Fernet(key)
with open(filename, 'rb') as file:
original = file.read()
encrypted = fernet.encrypt(original)
with open(filename, 'wb') as enc_file:
enc_file.write(encrypted)
key = Fernet.generate_key()
filename = "file.txt"
encrypt(filename, key)
|
生成密钥,然后对文件内容进行加密,当然这个密钥后面在对文件进行解密的时候会派上用场,因此密钥一定要保存完好,解密的代码如下

| def decrypt(filename, key):
fernet = Fernet(key)
with open(filename, 'rb') as enc_file:
encrypted = enc_file.read()
decrypted = fernet.decrypt(encrypted)
with open(filename, 'wb') as dec_file:
dec_file.write(decrypted)
decrypt(filename, key)
|
上面的脚本,其中的密钥是一个随机生成的随机数,当然密钥也可以自己指定的,代码如下

print("File has been decrypted")
def Decryption(input_file_path, output_file_path, key):
pyAesCrypt.decryptFile(input_file_path, output_file_path, key)
print("File has been decrypted")
