使用python加密/解密文件

Question

有沒有一種方法可以使用python來加密/解密文件（類似於Axcrypt）？

Answer 1

這樣的SO Q＆A （如何使用PGP進行加密/解密）怎么樣？

Answer 2

檢查http://github.com/slideinc/PyECC ， http://sourceforge.net/projects/cryptopy/和http://www.dlitz.net/software/pycrypto/ （發現全部由搜索“密碼”在HTTP ：//pypi.python.org/pypi ）

Answer 3

在python文檔中轉到此處以獲取可用於加密的模塊： http : //docs.python.org/library/crypto.html

Answer 4

您可以嘗試進行加密和解密。

#!/usr/bin/env python2.7
# -*- coding: utf-8 -*-
import nacl.secret
import nacl.utils
import base64
from pyblake2 import blake2b
import getpass

print "### ENCRYPTION"
key = blake2b(digest_size=16)
key.update(getpass.getpass("PASSWORD:"))
key = key.hexdigest()

print "key: %s" % key
box = nacl.secret.SecretBox(key)

# This is our message to send, it must be a bytestring as SecretBox will
#   treat is as just a binary blob of data.
msg = b"whohooäööppöööo"
print "msg: %s" % msg
nonce = nacl.utils.random(nacl.secret.SecretBox.NONCE_SIZE)
print "nonce: %s" % nacl.encoding.HexEncoder.encode(nonce)
encrypted = box.encrypt(msg, nonce, encoder=nacl.encoding.HexEncoder)
print "cipher: %s " % encrypted

print "### DECRYPTION"
key = blake2b(digest_size=16)
key.update(getpass.getpass("PASSWORD:"))
key = key.hexdigest()

nonce = None
print "nonce: %s" % nonce
print "key: %s" % key
box = nacl.secret.SecretBox(key)

msg = encrypted
print "msg: %s" % msg

plain = box.decrypt(ciphertext=msg,encoder=nacl.encoding.HexEncoder)
print "plain: %s" % plain
