# -*- coding: utf-8 -*-
import rsa
# 先生成一对密钥，然后保存.pem格式文件，当然也可以直接使用
(pubkey, privkey) = rsa.newkeys(1024)
pub = pubkey.save_pkcs1()
pubfile = open('public.pem','w+')
pubfile.write(pub)
pubfile.close()
pri = privkey.save_pkcs1()
prifile = open('private.pem','w+')
prifile.write(pri)
prifile.close()
# load公钥和密钥
message = 'lovesoo.org'
with open('public.pem') as publickfile:
p = publickfile.read()
pubkey = rsa.publickey.load_pkcs1(p)
with open('private.pem') as privatefile:
p = privatefile.read()
privkey = rsa.privatekey.load_pkcs1(p)
# 用公钥加密、再用私钥解密
crypto = rsa.encrypt(message, pubkey)
message = rsa.decrypt(crypto, privkey)
print message
# sign 用私钥签名认证、再用公钥验证签名
signature = rsa.sign(message, privkey, 'sha-1')
rsa.verify('lovesoo.org', signature, pubkey)

from rsa.bigfile import *

p = publickfile.read()
pubkey = rsa.publickey.load_pkcs1(p)
with open('private.pem') as privatefile:

privkey = rsa.privatekey.load_pkcs1(p)
with open('mysec.txt', 'rb') as infile, open('outputfile', 'wb') as outfile: #加密输出
encrypt_bigfile(infile, outfile, pubkey)
with open('outputfile', 'rb') as infile2, open('result', 'wb') as outfile2: #解密输出
decrypt_bigfile(infile2, outfile2, privkey)
