我使用pycrypto庫的AES算法在python瓶中構建網站&。在註冊網頁時,我將加密的密鑰保存在文本文件中。在登錄頁面,我比較進入PWD與解密PWD,使用下面的代碼使用AES算法的python中的解密問題
def decryption(encryptedString,key_from_file):
PADDING = '{'
DecodeAES = lambda c, e: c.decrypt(base64.b64decode(e)).rstrip(PADDING)
#Key is FROM the printout of 'secret' in encryption
#below is the encryption.
encryption = encryptedString
key = key_from_file
cipher = AES.new(key) #### error comes here
decoded = DecodeAES(cipher, encryption)
return decoded
def login():
if request.method == 'GET':
return render_template('login.html')
if request.method == 'POST':
username = request.form['username']
password = request.form['password']
d2 = pandas.read_csv("Employee_Info.txt",header=0)
search_id = d2[d2['email'] == username]
pdb.set_trace()
if search_id.empty:
error = "username does not exists"
return render_template('login.html', error = error)
else:
pwd_from_file=search_id.iloc[0]['pwd']
key_from_file=search_id.iloc[0]['key']
if decryption(pwd_from_file,key_from_file) == password:
print "matching password"
else:
print "mismatch"
,但我得到的錯誤爲ValueError: AES key must be 16,24 or 32 bytes long.
文本文件有以下字段:
id,email,pwd,key
