【问题描述】:
我一直在尝试在 python 中生成一个临时 url,该 url 将一些我需要确保不会更改的数据,所以我会在最后添加一个哈希,但无论如何我都会以 bString 结尾我尝试了什么,谁能指出我做错了什么? 这是我的代码示例 哦,我知道也许改变算法/编码可能会解决问题,但我找不到合适的,任何投反对票的人都可以解释他投反对票的原因
import hashlib
import datetime
from Crypto.Cipher import AES
def checkTemp(tempLink):
encrypter = AES.new('1234567890123456', AES.MODE_CBC, 'this is an iv456')
decryption = encrypter.decrypt(tempLink)
length = len(decryption)
hash_code = decryption[length-32:length]
data= decryption[:length-32].strip()
hasher = hashlib.sha256()
hasher.update(data)
hashCode = hasher.digest()
if(hash_code==hashCode):
array = data.decode().split(",",5)
print("expiry date is :"+ str(array[5]))
return array[0],array[1],array[2],array[3],array[4]
else:
return "","","","",""
def createTemp(inviter,email,role,pj_name,cmp_name):
delim = ','
data = inviter+delim+email+delim+role+delim+pj_name+delim+cmp_name+delim+str(datetime.datetime.now().time())
data = data.encode(encoding='utf_8', errors='strict')
hasher = hashlib.sha256()
hasher.update(data)
hashCode = hasher.digest()
encrypter = AES.new('1234567890123456', AES.MODE_CBC, 'this is an iv456')
# to make the link a multiple of 16 by adding for AES with the addition of spaces
newData = data+b' '*(len(data)%16)
result = encrypter.encrypt(newData+hashCode)
return result
#print(str(link).split(",",5))
link = createTemp("name","email@homail.com","Designer","Project Name","My Company")
print(link)
inviter,email,role,project,company = checkTemp(link)

我没有投反对票,但你的问题读起来像是某人的意识流。添加一些标点符号、停句和大写,以帮助读者解析您上面写的内容。

@Hooked 谢谢,好吧,我是个新手,所以我不太擅长发表我的想法,而且我有点沮丧并且在尝试修复它时迷失了方向,这让我更加困惑。无论如何感谢您的指点
