Hi Guys,

Doing a practise app for a skool project (in that it has no real purpose and won't ever be used) and I'm trying to incorporate and very, very, very straightforward security/encryption technique so that when a user clicks a button (e.g. to submit a transaction) an encryption/security thing is run.

Are there any pre-made scripts for this or isit possible to write your own small-time encryption algorithm?

Appreciate any help!
