Encrypting text

[Sergio C.]

Hello,
I need to encrypt some text with a private key so that I can decrypt it
later with a public key, how can I do that?
(At the moment I can encrypt it with a public key and decrypt it with a
private key, and it doesn't work when I try to do what I want).

Thank you

Sergio C.

That's kind of a broad question...but you can check out this article for a
pretty good intro...
