[PYTHON] Encrypt and save data on jupyter and decrypt if necessary

This script was created with the idea that you would like to casually encrypt the password on the server, decrypt it, and use it.

#How to keep the password etc. encrypted on the server
#Save it with a common key and call it with jupyter.
#I wonder if it's okay for casual use

import gnupg
gpg = gnupg.GPG()

#Create text to save
conf = """
{'id':'foo',
'passwor':'bar'
}
"""
#Now text-encrypt with symmetric key bar
x = gpg.encrypt(conf, symmetric=True, passphrase='bar', encrypt=False)

#File test.Saved in txt Binary, utf-Make 8 texts.
f = open('test.txt','w')
f.write(x.data.decode('utf-8'))
f.close()

#Recall the saved file and decrypt it.
f = open('test.txt','r')
y = gpg.decrypt((f.read()), passphrase='bar')
conf = eval(y.data.decode('utf-8'))
print(conf)
