securestring

Analyze problems System. Security. securestring is designed to save confidential strings to do what traditional strings cannot do. Traditional strings are allocated in the memory in the form of clear code. A simple memory read/write software can easily capture these strings, which is not allowed in some confidential systems. Readers may think that string encryption will solve similar problems, but in fact, strings have been explicitly stored in the me

debugging and go to 019db820 (! DSO ). As Method1 is not entered yet, the memory does not contain the string "luminji ". Then let the program run into the method. We can see that there is already "luminji" in the memory. Then let the program continue running and exit Method1, and find that "luminji" remains in the memory. This poses a problem. If a malicious person scans your memory, the confidential information stored in your program will be nowhere to escape. Fortunately, system. Security.

The string object may contain some sensitive data, such as the user password.CodeThe code can scan the address space of the Process, find the string containing sensitive data, and use the data in an unauthorized way, even if the string object only takes a short time, then it will be collected by the garbage collector, and CLR may not be able to use the memory of the string object immediately, so that the characters of the string object are kept in the memory of the process for a long time, resul

In the previous article we learned how to use AES key to generate SecureString in different user account and workstations. We need to protect the key from the illegal decryption of data protection.In the previous example, I used a very simple 16-byte array to store the body of the script itself. This is not a good practice, which is essentially the same as your password in plaintext. Or you can generate a key in an isolated script in advance.As an exa

Maybe you think this is too simple to mention? However, in my projects, there are actually many places that apply to the extension method, but you are not aware of it. One major purpose of extension method is to construct an auxiliary method. To abstract and simplify the programming process, we will put some common methods that are difficult to create an object class for them into the so-called helper, and call helper. xxxx () during use (). For example: public static class Helper{ public sta

object type name of the $cred is: System.Management.Automation.PSCredential, where both password and username are properties, so you can create a new object of that type. It is important to note here that the password type is securestring,username type string, so you need to convert the plaintext password to a secure string, and you can use the convertto-securestring command.Example of a non-interactive Sa

. A string that has the same content is actually just the same string on the memory heap. It is said to be most, but not all, because a part of the dynamically created (concat) string is not entered into such a virtual hash table. The end of this article is attached to the string class source code, interested students can study. This brings up the main problem that you cannot accurately control or predict the life cycle of a particular string. A sensitive data, such as a password, that is prese

The NET Framework 4.5 ADO database connection supports the use of SecureString memory flow mode for confidential text . Once this type of operation is used, the text encryption is private and can be removed from the computer's memory when it is no longer needed. SecureString This class cannot be inherited. Here are some demos private void Login_click (object sender, EventArgs e) {//login parameter string

in our daily use Exchange Management Shell the most should be the management of the mailbox. In this section, you will primarily describe the use of syntax commands in Exchange to Create, update, and delete mailboxes in your organization. Let's look at an example first:1. We can use the Exchange Management Shell to create an AD account that has the mailbox feature enabled . The syntax is as follows:$password = Convertto-securestring-asplaintext Abc.

Applicable to Powershell3.0 and later versions.Let's say you need to encrypt your files, and here's how to encrypt your files: $Path = "$env: Temp\secret.txt" $Secret = ' Hello world!

creating an object and write it into the script. Next, let's take a look at the $ A object type and its corresponding attributes. We can know that the object type name is: system. management. automation. pscredential, where the password and username are both attributes, so you can create a new object of this type. Note that the password type is securestring and the username type is string. Therefore, you need to convert the plaintext password to a se
