Druid database user password Encryption code implementation _ encryption

Druid-1.0.16.jar Alibaba's open source data connection pool Jar pack

PlainText password + private key (Privatekey) encryption = encrypted password

Encryption password + Public key (publickey) decryption = plaintext password

The program code is as follows:

Package com.t1;

Import Com.alibaba.druid.filter.config.ConfigTools;

public class Druidtest {public

 

    static void Main (string[] args) throws Exception {

    //password plaintext

    String password = "1 2345 ";

     

    The encrypted information of SYSTEM.OUT.PRINTLN ("Password [" +password+ "] is as follows: \ n");

 

    String [] KeyPair = Configtools.genkeypair (a);

    Private key

    String privatekey = keypair[0];

    Public key

    String publickey = keypair[1];

    Ciphertext

    password = configtools.encrypt (privatekey, password) encrypted with the private key;

 

    System.out.println ("Privatekey:" +privatekey);

    System.out.println ("PublicKey:" +publickey);

    System.out.println ("Password:" +password);   

    String decryptpassword=configtools.decrypt (publickey, password);

    System.out.println ("Decryptpassword:" +decryptpassword);

     

 

    }
