recently I've been working with JavaServerPager (JSP), there is a form that queries data from a database, but the data is returned encrypted, I have tried some methods to decrypt, but it seems that they are not the correct ones, here are some plain text samples and how it returns them encrypted I hope you can help me to know what type of encryption is used. :)
