I Found this piece of code on jasypt.org I want to know what encryptor.setPassword("jasypt") does. Is it the Cryptographic key? What happens if i don't set the password? I've been reading about "Keys", how do i find it? Where do i securely store this key?

PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
encryptor.setPoolSize(4);          // This would be a good value for a 4-core system
encryptor.setPassword("jasypt");
encryptor.setAlgorithm("PBEWithMD5AndTripleDES");

  • That's a lot of questions. Most can be answered by looking into the code of jasypt (it's open source). The last question cannot be answered without a detailed description of your use case, but since you're asking, there is a chance that your use case doesn't make sense. – Artjom B. Aug 04 '17 at 17:01
  • Artjom, Im trying to build a symmetric encryption application. And all of the online videos talk about some key. I do not understand what it is. And they ask one to store it securely. Im sure any cryptographic algorithm will use a key. So i wanna know more about it – Sumanth Saligram Aug 04 '17 at 17:03
  • A cipher needs a key. A scheme might use a key, but it might also take something else. The PBEWithMD5AndTripleDES scheme takes a password. Please don't confuse keys and passwords. – Artjom B. Aug 04 '17 at 17:21
