1. Simple TCP service encryption using TLS/SSL sslwrap is a simple Unix service that sits over any simple TCP service such as POP3, IMAP, SMTP and encrypts all of the data on the connection using TLS/SSL. It uses openssl to support SSL version 2 and 3. It can be run out of inetd. It can also encrypt data for services located on another computer. It works with the servers you already have and does not require any modifications to your existing servers. More information can be found at the sslwrap web site http://www.rickk.com/sslwrap/ .
