Luks (Linux unified key setup) provides a standard for Linux hard disk encryption. It not only applies to different Linux Release versions, but also supports multiple users/passwords, because its encryption key is independent of the password, even if the password is lost, we do not need to re-encrypt the entire hard disk, just change the password in time to regain security!
Luks provides a standard disk
Introduction to des algorithm Description:Des is the abbreviation for the data Encryption standard. It is a cryptographic algorithm developed by IBM, the United States National Standards Bureau published in 1977 to use it as a non-confidential department of Data encryption standards; It is a packet encryption algorithm that encrypts data in 64-bit groupings. Des

Encryption of common Asp. Net tools-asymmetric encryption RSA algorithm, asp. netrsa
After several years of entering the programmer industry, there have been gains (enhanced technology) and efforts (time and sub-health status) in the past few years ). Of course, there is no regret, and the code is still long !!!
On The Way, never stop !!!
In the development process, I have also accumulated some exp
The difference between 16-bit MD5 encryption and 32-bit MD5 encryptionMD5 encryption is usually a 32-bit encoding, and in many places will use 16-bit encodingWhat difference do they have?16-bit encryption is to extract the middle 16 bits from the 32-bit MD5 hash!Actually cracked 16-bit MD5 hash is slower than cracking 32-bit MD5 hashBecause he has one more step,
Several common encryption functions in PHP and common encryption functions in PHP
MD5 encryption:
String md5 (string $ str [, bool $ raw_output = false])
1. by default, md5 () returns a hash value in the hexadecimal format of 32 characters. It accepts two parameters: the first is the string to be encrypted, and the second is the Boolean value of raw_output, the d

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After fi
In addition to DES, we also know that there are Desede (TripleDES, 3DES), AES, Blowfish, RC2, RC4 (Arcfour) and other symmetric encryption methods, the implementation of the same way, here is another algorithm of symmetric encryption--PBE PBE pbe--password-based Encryption (password-based encryption). It is characte
This article mainly introduces the practical PHP shared Encryption Class with public key. This class achieves different encryption results each time, but there is no problem with decryption. It is a very practical Encryption Class, for more information, see

Resource protection is often encountered in game development.
Currently, files that are often encrypted in game development include images, Lua files, and audio files. encryption is a double-edged sword.
To ensure security, you need to spend a certain amount of resources to implement it. Currently, the texturepacker tool is also used for encryption on
Android database encryption and android Database Encryption
1 Introduction
SQLite is a lightweight, cross-platform, open-source database engine. It has advantages in terms of read/write efficiency, total resource consumption, latency, and overall simplicity, make it the best solution for mobile platform databases (such as Android and iOS ). The Android system has a built-in SQLite database and provides a co
