using the same password is the same.
It is generally known that the MD5 method is configured in pg_cmd.conf to access encryption, so the password data stored in the User table should also be md5 encrypted data, but it is unknown how to combine encryption.
Recently, when I read this source code, I found that the

For any relational database, tables are the core and basic object units of data storage. Now let's start from here.1. Create a table:Copy codeThe Code is as follows:Create table products (Product_no

In the real environment, we will encounter the loss or theft of database backup disks. At this time, malicious destructive parties only need to restore or attach the database to view data. Next, I will introduce the Transparent Data Encryption method to protect your database. If data A is encrypted using TDE, the datab
Comments: Piracy is a worrying issue for most software developers. Will the software encrypted with encryption locks be cracked by hackers? Theoretically, there is no software that cannot be cracked. Even pure mathematical encryption may be cracked, but the time for cracking may be an astronomical number. Currently, there are two types of encryption locks on the

A colleague consulted me about the implementation of Android DES Encryption, a simple implementation, today to sum up.

Oracle's transparent data encryption is part of Oracle's Advanced Security Options and requires additional software fees. This option can be encrypted in combination with multiple means, including using Wallet (PKCS #12 standard) and supporting PKCS #11 RAS hardware devices.
In 10 Gb, transparent encryption supports column-level

Those who know Data Encryption technology are sure to be confident in its ability to protect the security of data sources. Because of the direct effect on data, even if the data is lost or stolen in the security crisis, encryption

Asymmetric encryption algorithms are relative to symmetric encryption algorithms. For more information about symmetric

Use of certificates combined with symmetric encryption algorithm to add and decrypt Long dataThe previous section discussed how to encrypt data using RSA certificates, which mentions: "The RSA implementation of dotnet has a characteristic that it must add some random numbers in the clear text, so the plaintext cannot fill 128 bytes,

Introduction to MD5: MD5 is the Message-Digest Algorithm 5 (Information-Digest Algorithm 5), used to ensure the integrity and consistency of information transmission. It is one of the widely used Hash Algori
Typically, when using a feature service, the user requires that the data be stored in a spatial database. At the same time, you need to register the database with ArcGIS for Server so that you do not need to copy the data when you publish the service, which saves disk space and service release time. The following summarizes how the PostgreSQL database is used in
Recently accidentally and colleagues to exchange data security transmission problems, think of their own used RSA asymmetric encryption algorithm, idle down to sum up.
What is RSA encryption?
RSA algorithm is the most popular public key cryptography algorithm, using the length can change the key. RSA is the first algorithm that can be used both for

All we need to do is to declare a column to be encrypted and the rest to be done by Oracle. When the user inserts or updates data, the column values are intercepted, encrypted, and then saved in the encrypted format. Then, when the column is queried, the value of the column is automatically decrypted, and the decrypted text (plaintext) is returned to the user. Users do not even need to know that there has been enc
These days the company temporarily pulled to do Android IM instant Messaging protocol implementation, the general view of their agreement, because the previous did not participate, is said to be due to server performance restrictions, only to achieve a non-clear delivery, specific reasons I am not clear, but the encryption used here is the use of XOR or encryption.
