How to encrypt communication between servers when merge

I want to know how to obtain an encrypted communication
between two SQL Servers using Replication.
I saw that using SSL is posible to grant secure
communication between client an server, but how can i
encrypt communication between two servers?
Hector,
as far as I understand, The SSL encryption applies to all inter-computer communication protocols supported by SQL Server 2000. Alternatively you can use Multi-protocol with encryption facility, for more information review books online.
