Database storage is a kind of storage that we often use, I believe most of our friends are familiar with the way i

It's early to know about QT, but I haven't had the patience to do an exercise. Recently spent almost two weeks to do a QT development exercise, basically complete the introduction of QT, escaped the Microsoft platform and took a few small steps. Although QT is a C + +, but the development of the application is more convenient, I think it in the interface design, message delivery, more than Delphi, and even in some aspects better than. NET WinForm. The threshold for getting started is the relativ

First to describe the situation, first there is a batch of users before the default password for 6 8 and then after the MD5 encryption for storage, it is now necessary to change according to the user ID number 6 digits as the password.1. First found that we sqlserver05 the above version is the MD5 encryption method, and then we verify that its encrypted data with the. NET comes with the MD5

Because JDK6 must be used as a Java environment in the project, there was a com.microsoft.sqlserver.jdbc.SQLServerException when connecting to SQL Server: The driver failed to use Secure Sockets Layer (SSL) Encryption establishes a secure connection with SQL Server. Error: "Java.lang.RuntimeException:Could not generate DH keypair". Such a mistake.This is fixed in

The principle of replacing the cryptographic algorithm is to use the replacement method for encryption, that is, replacing characters in plain text with other characters to form the ciphertext. For example, the plaintext letters a, B, c, and d are replaced with D, E, F, and G to form the ciphertext. Here, in the Oracle stored procedure, the encryption algorithm is replaced to encrypt the password stored in

Using vs.net for WinForm + MS SQL programming, we'll start with the following things: Connect to a database (if you are typically using Windows integration validation, this article may not need to be looked at) Suppose you are using the SA + Password authentication method; Add a new data source; Vs.net here to remind us that the connection string contains sensitive information; Save the connection string to

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

Stored Procedure Encryption The reasons for use are as follows:1, the use of stored procedures, at least in the prevention of illegal injection (inject) to provide better protection . At the very least, pre-compilation is performed first before the stored procedure executes, (if the cause of an illegal argument) is not executed, which in some way provides a layer of natural barrier.2. Using stored procedures instead of direct access to the base table
