# -*- 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 * 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) |
