如何在C＃的Windows凭据中传递长字符串作为密码？ [英] How to pass long string as password in windows credentials in C#?

问题描述

我在使用c＃和Credential Manager API传递一个长字符串以保存到windows vault文件夹时遇到异常。否则它会成功保存到保险库。



例外情况是

I am getting exception while passing a long string to save to the windows vault folder using c# and Credential Manager API. Else it is getting saved successfully to the vault.

Exception coming is

Specified argument was out of the range of valid values.

Parameter name: The password has exceeded 512 bytes.

&



传递的密码字符串为< br $> b $ b

我的尝试：

&

password string passed is "TERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRTGVBFXDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDTREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEECFGBBCVBDRFGDXFXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXRETWEREWRW3ERWERWRWRWRRRRRRRRRRRRRRRRRRRRRFDSFFFSDFSFSFSFDSFDDFSFSFSFGRWERWREWRWRWRDXVGFDGFDGFDGFDGDGDFGDGDGDREWRWREWRERRWREWREWRDXVCXBCVVVVVVVVVVVVVVREWRWERRRRRRRRRRREWRWRWREWR"

What I have tried:

public void SavePassword(string password)
       {
           try
           {
               using (var cred = new Credential())
               {
                   cred.Password = password;
                   cred.Target = PasswordName;
                   cred.Type = CredentialType.Generic;
                   cred.PersistanceType = PersistanceType.LocalComputer;
                   cred.Save();
               }
           }
           catch(Exception ex)
           {

           }

       }

推荐答案

Parameter name: The password has exceeded 512 bytes.

您的密码长度为600字节，允许的最大密码为512.

Your password is 600 bytes long and the maximum allowed is 512.
