Use openssl command to generate public key and private key // Generate private key # openssl genrsa -out rsa_private_key.pem 1024 // Generate public key # openssl rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem Here is the sample code:

1. Detailed introduction to PHP using openssl extension to implement public key encryption

Introduction: Use openssl command to generate public and private keys // Generate private key # openssl genrsa -out rsa_private_key.pem 1024 // Generate public key # openssl rsa -in rsa_private_key. pem -pubout -out rsa_public_key.pemThe following is the sample code:

2. Simple case of RSA encryption algorithm

Introduction: RSA encryption algorithm is currently the most influential public key encryption algorithm. It can resist the Most known password attacks. What are the applications of the RSA encryption algorithm? The following is a case of database authentication. When using a data set for authentication, the password is stored in the database, and the password entered by the user during authentication is the same as that in the database. If the password is the same, the authentication will be passed. If the database is cracked, it will pose a threat to the system. How to ensure the security of the system? The RSA encryption algorithm can be used to encrypt the permissions. Idea: When the user name and password are passed in the URL...

5. Issues related to PHP public key encryption

Introduction: Regarding the issue of PHP public key encryption, I plan to use PHP's own SSL function to complete the public key encryption work. But when accessing this test.php file, the web page will keep loading, and then IE will prompt that the web page cannot be displayed. Please take a look and see if I wrote the code wrong or if there are other problems. Because the PHP editor did not report an error, I suspected that it was a problem with my Apache server configuration. The code is as follows: Issues related to asymmetric encryption of json strings

Introduction: json string asymmetric encryption problem This post was last edited by gwrc_s_d_n on 2013-08-12 10:20:07 ​ ​ ​ ​ Another project recently required sending http requests in PHP, and using asymmetric encryption. The part that needs to be encrypted is the json string. The current test problem is that if you directly use the public key to encrypt the json string and send it to the server, the decryption will fail (the client tests the encryption and then decrypts normally). If base
