Article Introduction：Recently, 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.

Article Introduction：: PHP's phpass encryption algorithm: The md5 method has been used before for password encryption. The md5-encrypted password can be forcibly cracked. Online searches found that the bcrypt algorithm can be used, which has a high security factor. Currently, both the YII framework and wordpress are using this algorithm. phpass is an open source class library that allows us to easily use the bcrpt encryption algorithm.

Article Introduction：The basic process of data encryption is to process files or data that were originally plain text according to a certain algorithm, turning it into an unreadable piece of code, usually called ciphertext, so that it can only be displayed after entering the corresponding key. Original content, through this way, the purpose of protecting data from being stolen and read by illegal persons is achieved.

Article Introduction：The base JCA is divided into three main components: Providers: Provide implementations of specific algorithms and services. Java provides several built-in providers, including SunPKCS11 and BC. Algorithm: The algorithm implemented by the provider, such as AES, RSA, and SHA-256. Transformation: Combining algorithms to perform complex operations such as encryption and decryption, signing, and verifying signatures. Crypto JCA provides full support for symmetric and asymmetric encryption. For symmetric encryption, algorithms such as AES, DES and Blowfish can be used. For asymmetric encryption, JCA supports algorithms such as RSA, DSA and ECC. Hash A hash function is used to create a unique identifier for a message. JCA provides a variety of hashing algorithms, including SHA-256, S

Article Introduction：Encryption algorithms can be divided into two types according to the type of key: "asymmetric key encryption algorithm" and "symmetric key encryption algorithm". Asymmetric key encryption algorithm refers to an encryption algorithm that uses different keys for encryption and decryption; symmetric key encryption algorithm refers to an encryption algorithm that uses the same key for encryption and decryption.
