PHP Data encryption. Data encryption has become more and more important in our lives, especially considering the large amount of data that has been traded and transmitted over the Internet. It is assumed that data
PostgreSQL 9.4 is loading a new feature called JSONB, a new type of data that can store JSON data that supports gin indexes. In other words, this feature, in the upcoming update, most importantly, if this is not important, then put Postgres in the file as the recommended location for the database system.
Since 9.2, a consolidated JSON

"Guide" This article describes how to easily integrate data encryption into a database application using the new functions provided in IBM DB2 Universal Database Version (Unix Windows).
Over the years, the database has been able to prevent unauthorized people from seeing the data, which is usually done through privileges and permissions in the database manager.
[Oracle] Transparent Data Encryption technology-TDE the full name of Oracle TDE is Transparent Data Encryption. It supports column-based Encryption from 10gr2 and table space-based Encryption from 11 GB. It is transparent to appli

Design of secure login authentication for websites
", It may be that the story is not clear enough. One reader left a message and questioned it,"As the name suggests, the Public Key is public. As long as you want it, everyone will have your public key. How can it be secure?It should be encrypted with the public key of the website. After being uploaded to the website, the website will be decrypted with its own private key ".
These cryptographic concepts are
Objective:
For the SHA Safe hashing algorithm, before how to use, just stay in the heard of the stage, today in the picture Caching framework Glide source code found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption algorithm, this just reminded me of curiosity, so take advantage of the evening nothing, To learn.
Several other encryption
In order to ensure the security and integrity of the data, it is often necessary to encrypt the data, and data encryption can prevent the interception in the middle of the transmission process. We usually refer to the original data is called the source text, with the agreed

If you are running a Web application that uses MySQL, it can store passwords or other sensitive information in the application. Protecting this data from access by hackers or prophers is an important concern, because you cannot allow unauthorized users to use or destroy applications, but also ensure your competitive advantage. Fortunately, MySQL comes with a lot of encryption functions designed to provide t
E-Commerce uses data encryption to protect databases (2)I explained some theoretical content in the previous article. This time we will introduce the example in detail:
For example, we create a class desutil. Java
As mentioned last time, I need to create a key first, so I need to add a method to create the des key first. For ease of use, we temporarily write all the methods as static methods.// Filename is
Oracle TDE transparent data encryption technology
From ORALE 10GR2, Transparent Data Encryption technology (TDE) emerged ).
