1 安裝rsa 2 python -m pip install rsa
我們可以生成RSA公鑰和密鑰，也可以load一個.pem文件進來
1 # -*- coding: utf-8 -*- 2 import rsa 3 4 # 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 5 (pubkey, privkey) = rsa.newkeys(1024) 6 7 pub = pubkey.save_pkcs1() 8 pubfile = open('public.pem','w+') 9 pubfile.write(pub) 10 pubfile.close() 11 12 pri = privkey.save_pkcs1() 13 prifile = open('private.pem','w+') 14 prifile.write(pri) 15 prifile.close() 16 17 # load公鑰和密鑰 18 message = 'lovesoo.org' 19 with open('public.pem') as publickfile: 20 p = publickfile.read() 21 pubkey = rsa.PublicKey.load_pkcs1(p) 22 23 with open('private.pem') as privatefile: 24 p = privatefile.read() 25 privkey = rsa.PrivateKey.load_pkcs1(p) 26 27 # 用公鑰加密、再用私鑰解密 28 crypto = rsa.encrypt(message, pubkey) 29 message = rsa.decrypt(crypto, privkey) 30 print message 31 32 # sign 用私鑰簽名認證、再用公鑰驗證簽名 33 signature = rsa.sign(message, privkey, 'SHA-1') 34 rsa.verify('lovesoo.org', signature, pubkey)
