以下脚本encrypt_me.py(

modified from another post)使用gpg加密自身并以装甲形式打印出密文.

但它只适用于python2.7但不适用于python3？你知道它在python3上运行时有什么问题吗？

import subprocess

import shlex

import os

import sys

in_fd, out_fd = os.pipe()

passphrase = 'passsssphrase'

os.write(out_fd, passphrase.encode('utf-8'))

os.close(out_fd)

cmd = 'gpg --passphrase-fd {fd} -c --armor'.format(fd=in_fd)

with open(__file__,'r') as stdin_fh:

proc=subprocess.Popen(shlex.split(cmd),

stdin=stdin_fh,

stdout=sys.stdout)

proc.communicate()

os.close(in_fd)

使用python2.7：

$python encrypt_me.py

Reading passphrase from file descriptor 3
