一、python
1、 des3
python平台的DES3 + base64 加密解密, 有两个常用的库pycrypto和pyDes
1)pycrypto
des3.py
#coding=utf-8
from Crypto.Cipher import _DES3
import base64 import json BS = _DES3.block_size def pad(s): return s + (BS - len(s) % BS) * chr(BS - len(s) % BS) #定义 padding 即 填充 为PKCS7 def unpad(s): return s[0:-ord(s[-1])] class prpcrypt(): def __init__(self, key): self.key = key self.mode = _DES3.MODE_CBC #模式为CBC self.iv = IV #self.iv 为 IV 即偏移量,ECB模式不使用IV # DES3的加密模式为CBC def encrypt(self, text): text = pad(text) cryptor = _DES3.new(self.key, self.mode, self.iv) x = len(text) % 8 if x != 0: text = text + '\0' * (8 - x) # 不满16,32,64位补0 # print(text) self.ciphertext = cryptor.encrypt(text) return base64.standard_b64encode(self.ciphertext).decode("utf-8") # DES3的解密模式为CBC def decrypt(self, text): cryptor = _DES3.new(self.key, self.mode, self.iv) de_text = base64.standard_b64decode(text) plain_text = cryptor.decrypt(de_text) # st = str(plain_text.decode("utf-8")).rstrip('\0') # out = unpad(st) # return out #上面注释内容解密如果运行报错,就注释掉试试 return plain_text if __name__ == '__main__': #ECB模式不使用IV IV=b'00000000' des3 = prpcrypt('123456789012345678901234') # 自己设定的密钥 tick = { "protocolHead": "gis_fl", "protocolType": 1000000 } js = json.dumps(tick) #字典转str,再加密 #js = str(tick) print type(js) e = des3.encrypt(js) # 加密内容 d = des3.decrypt(e) #解密内容 print e #加密后 print d #解密后

二、nodejs
1、 des3加密

感谢这位哥,轻轻一百度就有现成的

var assert = require('assert'); var crypto = require('crypto'); function test_des(param) { var key = new Buffer(param.key); var iv = new Buffer(param.iv ? param.iv : 0) var plaintext = param.plaintext var alg = param.alg var autoPad = param.autoPad //encrypt var cipher = crypto.createCipheriv(alg, key, iv); cipher.setAutoPadding(autoPad) //default true var ciph = cipher.update(plaintext, 'utf8', 'hex'); ciph += cipher.final('hex'); console.log(alg, ciph) //decrypt var decipher = crypto.createDecipheriv(alg, key, iv); decipher.setAutoPadding(autoPad) var txt = decipher.update(ciph, 'hex', 'utf8'); txt += decipher.final('utf8'); assert.equal(txt, plaintext, 'fail'); } test_des({ alg: 'des-ecb', autoPad: true, key: '01234567', plaintext: '1234567812345678', iv: null }) test_des({ alg: 'des-cbc', autoPad: true, key: '01234567', plaintext: '1234567812345678', iv: '12345678' }) test_des({ alg: 'des-ede3', //3des-ecb autoPad: true, key: '0123456789abcd0123456789', plaintext: '1234567812345678', iv: null }) test_des({ alg: 'des-ede3-cbc', //3des-cbc autoPad: true, key: '0123456789abcd0123456789', plaintext: '1234567812345678', iv: '12345678' })
我只用到了3des-ecb,数据格式是base64, 将加密和解密两个函数的数据格式从hex改成base64就OK了。
封装一下
var crypto = require('crypto'); var key_qbox10 = '123456789012345678901234'; function des3Encrypt(param) { var key = new Buffer(param.key); var iv = new Buffer(param.iv ? param.iv : 0) var plaintext = param.plaintext var alg = param.alg var autoPad = param.autoPad var cipher = crypto.createCipheriv(alg, key, iv); cipher.setAutoPadding(autoPad) var ciph = cipher.update(plaintext, 'utf8', 'base64'); ciph += cipher.final('base64'); return ciph; }; function des3Decrypt(param) { var key = new Buffer(param.key); var iv = new Buffer(param.iv ? param.iv : 0) var plaintext = param.plaintext var alg = param.alg var autoPad = param.autoPad var decipher = crypto.createDecipheriv(alg, key, iv); decipher.setAutoPadding(autoPad) var txt = decipher.update(plaintext, 'base64', 'utf8'); txt += decipher.final('utf8'); return txt; }; exports.decode=function(data){ var para = { alg:'des-ede3', autoPad:true, plaintext:data, iv:null, key:key_qbox10 }; var decode_str = des3Decrypt(para); return decode_str; } exports.encode =function(data){ var para = { alg:'des-ede3', autoPad:true, plaintext:data, iv:null, key:key_qbox10 }; var encode_str = des3Encrypt(para); return encode_str; }
demo:
decode
function recv_routine(data){ var obj = JSON.parse(des3.decode(data)); //console.log("<<<<<<<<<<<<<<<<<<<<"+JSON.stringify(obj)); //response tick if( obj.protocolType === 1000000 ){ console.log("<<<<<<<<<<<<<<<<<<<<"+JSON.stringify(obj)); } }
encode
client.connection.sendUTF(des3.encode(JSON.stringify(proto.tick)));
