What does data encryption storage include?

Data encryption storage includes technologies and methods such as symmetric encryption, asymmetric encryption, hash functions, data encryption algorithms, key management, multi-factor authentication and secure storage devices. Detailed introduction: 1. Symmetric encryption, fast and simple encryption and decryption process; 2. Asymmetric encryption, providing higher security; 3. Hash function, which is irreversible, that is, the original data cannot be restored from the hash value. ; 4. Data encryption algorithm, which performs complex mathematical operations on data so that unauthorized users cannot decrypt the data; 5. Key management, etc.

What is the most representative of symmetric encryption algorithms?

The most representative of the symmetric encryption algorithms is: DES encryption algorithm; DES encryption uses a block encryption method, using a 56-bit key to encrypt 64-bit plaintext, and finally generates a 64-bit ciphertext; algorithm features: relatively short blocks, key If it is too short, the password life cycle will be short and the operation speed will be slow.

What is the difference between symmetric encryption and asymmetric encryption

Differences: 1. In symmetric encryption, the same secret key is used for encryption and decryption; in asymmetric encryption, two keys are used. Generally, the public key is used for encryption and the private key is used for decryption. 2. Symmetric encryption and decryption are relatively fast, while asymmetric encryption and decryption take a long time and are relatively slow. 3. Symmetric encryption has relatively low security, while asymmetric encryption has high security.

In PHP, what does hash function mean?

A hash function is any function that can be used to map data of any size to data of a fixed size. The value returned by a hash function is called a hash value, hash code, digest, or simply hash. Syntax stringhash(string$algo,string$data[,bool$raw_output=FALSE]) Parameter algo The name of the selected hash algorithm (such as "md5", "sha256", "haval160,4", etc.) data to be hashed information. When raw_output is set to TRUE, raw binary data is output. FALSE outputs lowercase hexadecimal. Example<?php &nbsp

What is data encryption algorithm

The data encryption algorithm is a symmetric encryption algorithm and is the most widely used key system, especially in protecting the security of financial data; the cryptographic algorithm is the collective name for encryption algorithms and decryption algorithms. It is the core of the cryptographic system. The cryptographic algorithm can Seen as a combination of exchanges, when the input is plaintext, after these transformations, the output is ciphertext, and this process is an encryption algorithm.

Introduction to key management and protection mechanisms in PHP

Introduction to key management and protection mechanisms in PHP With the development of the Internet and the increasing importance of information security, key management and protection have become important issues that every developer needs to pay attention to. In PHP, key management and protection mechanisms are one of the key elements to ensure system security. This article will introduce how to manage and protect keys in PHP and provide relevant code examples. Key management refers to the process of generating, storing, and using keys. In PHP, generating keys can be achieved using random number functions or professional encryption libraries.

PHP password encryption and secure storage method

With the continuous development and popularization of the Internet, the security of user passwords has attracted increasing attention when performing various operations online. As a commonly used server-side programming language, PHP also has its own set of implementation methods for password encryption and secure storage. This article will introduce how PHP encrypts and secures passwords, helping readers understand and protect their user passwords. 1. Password encryption Password encryption refers to converting user passwords to generate a seemingly random sequence of characters. Even if a hacker obtains this character sequence, it cannot be restored to
