jasypt-spring-boot use

1. Maven dependencies
   

   <dependency>
   　　<groupId>com.github.ulisesbocchio</groupId>
   　　<artifactId>jasypt-spring-boot-starter</artifactId>
   　　<version>1.14</version>
   </dependency>

   
   
   
2. encrypted password
   

   The encryption command is as follows (the red part represents the password that needs to be encrypted):

   java -cp F://.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="test123" password=e9fbdb2d3b21 algorithm=PBEWithMD5AndDES

   
   The command echo is as follows (the red part is the encrypted ciphertext):

   

   ----ENVIRONMENT-----------------
   Runtime: Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 25.121-b13
   ----ARGUMENTS-------------------
   algorithm: PBEWithMD5AndDES
   input: test123
   password: e9fbdb2d3b21
   ----OUTPUT----------------------
   ArGx5ir2xs+CmXRhMnThpQ==

   

    

3. Set the ciphertext in the program
   

   To set the ciphertext in the program, you need to use the following format:

   ENC (ciphertext)
   Such as:
   spring.datasource.password=ENC(ArGx5ir2xs+CmXRhMnThpQ==)

   The spring.datasource.password obtained in the program will be automatically converted into plaintext content (test123).

4. Configure ciphertext password
   

   Configure the JVM parameter (jasypt.encryptor.password) in the startup command and inject the password of the encrypted ciphertext.
   Such as:

   java -Dfile.encoding=UTF8 -Djasypt.encryptor.password=e9fbdb2d3b21 -jar -Xmx512m settlement.jar

   Note: The password of the ciphertext in the docker container can be set as an environment variable (eg: JASYPT_PASSWORD ), the above command can be modified as:

   java -Dfile.encoding=UTF8 -Djasypt.encryptor.password=${JASYPT_PASSWORD} -jar -Xmx512m settlement.jar
