What does data encryption storage include?
Data encryption storage is a technical means to effectively protect information security. By encrypting the original data, the data can be prevented from being illegally accessed and stolen during transmission and storage. In practical applications, data encryption storage can be achieved through various methods such as symmetric encryption, asymmetric encryption, hash algorithms, and digital signatures. At the same time, with the development of cloud computing technology, cloud storage encryption has gradually become an important direction for data encryption storage.
What does data encryption storage include?Data encryption storage includes symmetric encryption, asymmetric encryption, hash algorithm, digital signature and other methods. Detailed introduction: 1. Symmetric encryption. During the encryption process, the original data and key are calculated by the encryption algorithm to generate encrypted ciphertext; 2. Asymmetric encryption. During the asymmetric encryption process, the data encrypted with the public key only Can be decrypted with the private key and vice versa; 3. Hash algorithm, which can verify the integrity and consistency of the data during data transmission and storage; 4. Digital signature, etc.
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.
Implementation of symmetric encryption algorithm in phpRecently, I suddenly wanted to save some confidential things in the database, and then I thought about how to prevent others from understanding what is stored even if they enter the database, so the only way is to encrypt it; but we still have to read it ourselves, so we can only Find some symmetric encryption algorithms and decrypt them when we want to see them. The following introduces the implementation of a simple symmetric encryption algorithm in PHP.
Detailed explanation of how PHP implements consistent hashing algorithmHow to implement consistent hashing algorithm in PHP? This article mainly introduces the consistent hash algorithm implemented in PHP, and analyzes the relevant techniques of the PHP hash algorithm in the form of a complete example. It has certain reference value and friends in need can refer to it. I hope to be helpful.
