> I don't think it's a good idea to lift the initialization into `init`, `javax.crypto.Cipher` is not thread-safe and the method `org.apache.shardingsphere.encrypt.strategy.impl.AESEncryptor#encrypt` is definitely possible to be called by multiple threads, you'd better keep it as is, or at least put it into `ThreadLocal` After the thread shares the instance, there is indeed a thread safety problem. Do you have more detailed documentation on the thread safety of javax.crypto.Cipher? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
