Simply list the basic commands and share only my thoughts!First, the data addition / decryption principle explanationboth clients communicate on the Internet, in order to ensure the security of information, there is The SSL protocol is called a Secure Socket layer under the application layer above the TCP/IP model Transport layer. The goal is to encrypt the application layer's data to the client, and the so

The status of data encryption in our lives has become increasingly important, especially given the large amount of data that is being traded and transmitted over the network. If you are interested in adopting security measures, you will also be interested in understanding a range of security features provided by PHP. In this article, we'll cover these features an

the security of network data transmission is an important subject in the field of computer communication, and data encryption is the main method to ensure data security. The so-called data encryption, that is, through a certain al

1. Block passwordThe block cipher is the grouping of the number sequence divided into n after the plaintext message is encoded, and each group is transformed and output by the function of the key, which is the cipher text. Encrypt one data group at a time, and decryption uses the same key, so it is often referred to as symmetric encryption. Division leader n various symmetric

Objective:For the SHA Secure Hash algorithm, not used before, just stay in the heard of the stage, today in the picture cache frame Glide source found that its cache key is not MD5 encryption algorithm, but SHA-256 encryption algorithm, this just hook up my curiosity, so while the night nothing, To learn a bit.Several other encryption methods: RSA

The role of data encryption in our lives has become increasingly important, especially given the large number of transactions and data transmissions that occur on the web. If you are interested in adopting security measures, you will also be interested in understanding the range of security features provided by PHP. In this article, we will describe these feature

Trucrypt, PGP, FreeOTFE, BitLocker, DriveCrypt, and 7-zip, these cryptographic programs provide exceptionally reliable real-time encryption to ensure data security, avoid data loss, theft, and snooping. Few IT pros also need data security training, but we often hear of events like this: Computers or hard drives are st

I,Public KeyEncryptionAssume that I have two numbers: 1 and 2. I like the number 2 and keep it. I won't tell you (Private Key), and I will tell you that 1 is my public key. I have a file that cannot be viewed by others. I use 1 for encryption. Someone else finds this file, but he does not know that 2 is the decryption private key, so he cannot undo it. Only I can use number 2, that is, my private key, to decrypt it. In this way, I can protect the

Encrypt | solve | data A while ago to the Public Security Bureau to do the project, the use of public key encryption technology and symmetric key encryption technology. Information is encrypted through 3DES, and the key is routed through the RSA public key System. The client uses CPU card Ekey for decryption. However, in the process of system writing, it is found

BASE64 encoding algorithm of Android Data encryption preface: In front of the study summed up the usual development encountered in various data encryption methods, the end will be encrypted binary data Base64 encoding, play a two times the effect of

"Encryption algorithm" explanation: The basic process of data encryption is to deal with a certain algorithm for files or data that were originally plaintext. Make it unreadable a piece of code, usually called "ciphertext", so that it can only enter the appropriate key to display the original content, through such a w

decision for a database-driven solution created by most people is how to encrypt and store data so as to ensure its security and avoid spying. 　　 Which of the following SQL Server support can be used to encrypt objects and data? It is wise to discuss from the very beginning what SQL Server lacks, or what you should not do for the encryption part of SQL Server. 　

Windows 2000/XP/Server 2003 users must have heard of or been in contact with EFS. However, due to its complexity, data may be lost if it is difficult to do so. Therefore, many people do not use it. In fact, EFS is not as difficult as we think. The key is to really play with it. We need to master several key tricks ...... Term genie 　　EFS: Encrypting File System, which is used to encrypt the File System. It helps you encrypt files and folders stored on
