如何檢查存儲在PSQL DB中的哈希密碼

Question

我想通過對密碼進行哈希處理然后在PSQL DB上檢查哈希來驗證密碼

我正在嘗試比較哈希值-但我收到了Invalid Salt.錯誤Invalid Salt.

這是我的代碼：

@app.route("/hello", methods=["POST", "GET"])
 def hello():
 email = request.form.get("email")
 password = request.form.get("password")
 password = bcrypt.generate_password_hash(password).decode('utf-8')
 db.execute("INSERT INTO users (email, password) VALUES (:email, 
 :password)",{"email": email, "password": password})
 db.commit()

和

@app.route("/check", methods=["POST", "GET"])
def check():
    email = request.form.get("login_email")
    check_email_in_db = db.execute("SELECT COUNT(*) FROM users WHERE email = :email", {"email": email}).fetchall()
    if check_email_in_db[0][0] == 1 :
        email = request.form.get("login_email")
        password = request.form.get("login_password")
        retrive_password_from_db = db.execute("SELECT password FROM 
        users WHERE email = :email", {"email": email}).fetchall()
        retrive_password_from_db = retrive_password_from_db[0][0]
        if bcrypt.check_password_hash(password, retrive_password_from_db):
            return("this works")
        else:
            return("something is wrong")

好，我知道了。 我要做的就是在散列時指定回合：

password = bcrypt.generate_password_hash(password, 10).decode('utf-8')
