How can I do to encrypt in delphi / lazarus from server side and then decrypt with javascript in the client side? Of course the reverse process too Is there a way to do that? I think yes, but I don't know how.

Thanks

Server-side there are several possibilities,
I think DCPCrypt may be the easiest:

In the browser, You should use the TJSCrypto class. It is documented in
