Copy the code

To judge directly from the description of the error message, decryption failed.

Here are a few possible decryption failures:

The first: speculation decryption encryption and decryption is the cause of failure and the key is not consistent, namely jasypt. The encryptor. Password when using plug-in configuration and parameters of the different.

The second type: no Unlimited Strength Java Cryptography Extension is installed. Since DD was installed with Spring Cloud Config, I didn’t mention this in this case, which is usually the case for readers who haven’t been exposed to Spring Cloud yet. This was mentioned earlier in distributed Configuration Center (Encryption and Decryption), but since it is not part of a series, I will mention it here.

You can download the JCE installation package for your Java version from Oracle’s official website, for example, JCE8. It is a compressed package, unzip you can see the following three files:

README.txt
local_policy.jar
US_export_policy.jar
Copy the code

Jar and us_export_policy. jar files will be copied to $JAVA_HOME/jre/lib/security to overwrite the original default contents.
