Encrypting long text

[Sean Cole]

Hi all,
I'm trying to use RSA to encrypt data from a text field like an address or
notes. When I try to use the encrypt command I get a result 'message too
long'. What is the method for encrypting long or large data?

My current line of code:
               encrypt tData using rsa with public key tMyKey and
passphrase tMyPass

Thanks

Sean
