我已经像CI编码它们的存储一样登录名，密码凭据。因此，通过观察CI的解码，我写我自己的解密模块中的蟒蛇 -编码的笨然后解码在Python
// Like CI get_key
def getKey(self, key):
self.log.info("In getKey method with key : %s"%key)
md5Key = hashlib.md5()
md5Key.update(key)
return md5Key.hexdigest()
// Like CI base64_decode
def getBase64Decode(self, encString):
self.log.info("In getBase64Decode.")
b64DecString = base64.b64decode(encString)
return b64DecString
// Like CI _xor_decode
def xorDecode(self, string, key):
self.log.info("In xorDecode method with string : %s and key : %s"%(string, key))
mString = self.xorMerge(string, key)
if mString == self.FAILED:
self.log.info("xorMerge Failed!")
return self.FAILED
self.log.info("xor Merge returned %s"%mString)
dec = ''
for (x, y) in izip(mString[1:], cycle(mString)):
dec += ''.join(chr(ord(x)^ord(y)))
// Like CI _xor_merge
def xorMerge(self, string, key):
self.log.info("In xorMerge method. with string : %s and key : %s"%(string, key))
hashString = self.hashMethod(key)
if hashString == self.FAILED:
self.log.info("hasMethod failed!")
return self.FAILED
self.log.info("hash method retured : %s"%hashString)
xored = ''
for (x, y) in izip(string, cycle(hashString)):
xored += ''.join(chr(ord(x)^ord(y)))
// Like CI hash
def hashMethod(self, key):
self.log.info("In hash method with key : %s"%key)
hashStr = ''
try:
hashStr = hashlib.sha1(key).hexdigest()
except Exception, e:
self.log.info("Exception in sha1 %s"%str(e))
return self.FAILED
return hashStr
// Like CI decode
def decode(self, string):
self.log.info("In decode method. Decoding string : %s"%string)
securitySection = "security"
keyItem = "key"
key = self.config.get(securitySection, keyItem)
if not key:
self.log.info("Key Invalid")
return self.FAILED
key = self.getKey(key)
self.log.info("Encrypted key : %s"%key)
dec = self.getBase64Decode(string)
self.log.info("b64decoded string : %s"%dec)
xorDec = self.xorDecode(dec, key)
if xorDec == self.FAILED:
self.log.info("Decoding failed!")
return self.FAILED
self.log.info("Decoded string: %s"%xorDec)
return xorDec
上述所有方法都写在解密类解密模块。
所以，当我将加密字符串传递给解码方法时，我得到了一些奇怪的unicode字符串，而不是实际的凭据。当我使用CI对其进行检查时，xorMerge从上面的代码中得出的结果与CI中给出的_xor_merge不同。我究竟做错了什么？
