# -*- coding: utf-8 -*-import rsa# 先生成一對密鑰，然后保存.pem格式文件，當然也可以直接使用(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公鑰和密鑰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)# 用公鑰加密、再用私鑰解密crypto = rsa.encrypt(message, pubkey)message = rsa.decrypt(crypto, privkey)print message# sign 用私鑰簽名認證、再用公鑰驗證簽名signature = rsa.sign(message, privkey, 'sha-1')rsa.verify('lovesoo.org', signature, pubkey) |
