```py
from cryptography.fernet import Fernet
def Sample():
# 暗号化
key = Fernet.generate_key()
with open('.\\test.key', "wb") as key_data:
key_data.write(key)
with open('.\\sample.txt',"r") as file:
data = file.read()
print(data)
byte_data = data.encode()
f = Fernet(key)
encrypt_data = f.encrypt(byte_data)
with open('.\\sample.txt', "wb") as file:
file.write(encrypt_data)
print(encrypt_data)
def Sample2():
#復号
with open('.\\test.key', "rb") as key_data:
key = key_data.read()
with open('.\\sample.txt',"rb") as file:
encrypt_data = file.read()
print(encrypt_data)
f = Fernet(key)
decrypt_data = f.decrypt(encrypt_data)
print(decrypt_data.decode('utf-8'))
