Implement your own sha-256 hashing algorithm in PHP!

Hash is also called "hash". It receives any set of input information of any length and transforms it into a fixed-length data fingerprint through the hash algorithm. The fingerprint is the hash value. Overall, a hash can be thought of as a message digest.

How to perform AES encryption and decryption operations in Java

1. Background knowledge In cryptography, encryption algorithms are divided into one-way encryption and two-way encryption. Symmetric encryption means that the same key is used for encryption and decryption, including AES encryption, DES encryption, etc. Asymmetric encryption refers to the use of different keys for encryption and decryption, including RSA encryption, etc. One-way encryption includes digest algorithms such as MD5 and SHA, which are irreversible. Two-way encryption includes symmetric encryption and asymmetric encryption. Two-way encryption is reversible, and the key to the ciphertext exists. 2. Introduction to AES AES: Advanced Encryption Standard (Advanced Encryption Standard) is a block encryption standard adopted by the U.S. federal government and is currently the most popular symmetric encryption algorithm. It is a new generation block encryption algorithm used to replace DES.

How to use PHP and GMP to perform RSA encryption and decryption algorithms for large integers

How to use PHP and GMP to perform RSA encryption and decryption algorithm for large integers. The RSA encryption algorithm is an asymmetric encryption algorithm that is widely used in the field of data security. It implements the process of public key encryption and private key decryption based on two particularly large prime numbers and some simple mathematical operations. In the PHP language, the calculation of large integers can be realized through the GMP (GNUMultiplePrecision) library, and the encryption and decryption functions can be realized by combining the RSA algorithm. This article will introduce how to use PHP and GMP libraries to

How to solve the memory ecc error reported by the Linux server

Memory ECC errors reported on Linux servers usually indicate hardware memory errors. The processing steps are: 1. Check the system log to check whether there are error messages or warnings related to memory errors; 2. Refer to the server manufacturer's documentation to find and run the server's Use a memory diagnostic tool to determine the specific memory problem. 3. Try testing each module one by one to find out if a specific memory module is causing the problem. 4. Update the BIOS and firmware. 5. Contact the hardware vendor's technical support department.
