Python生成rsa密钥对操作示例
本文实例讲述了Python生成rsa密钥对操作。分享给大家供大家参考,具体如下:
# -*- 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)
对文件进行RSA加密解密
from rsa.bigfile import * import rsa 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) 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)
