Setting up encrypted tunnels

Filed under: Computer Software,Security Tools — Suramya @ 1:04 AM

Sometimes its desireable to setup an encrypted tunnel between two networked computers so that you can transfer data between them without letting anyone snoop the traffic.

The following are some of the programs that enable you to setup secure tunnels:

cryptcat:

Cryptcat is the standard netcat enhanced with twofish encryption.

stunnel:

Stunnel is a program that allows you to encrypt arbitrary TCP connections inside SSL. It allows you to secure non-SSL aware daemons and protocols (like POP, IMAP, LDAP, etc) by having Stunnel provide the encryption, requiring no changes to the daemon’s code.

zeebede:

Zebedee is a simple program to establish an encrypted, compressed â??tunnelâ?? for TCP/IP or UDP data transfer between two systems.

SSH Tunnels:

SSH allows you to redirect local and remote ports over a secure SSH connection. The main advantage of this is that no extra software needs to be installed on the systems in order to use it.

In you know of others let me know and I will add them.
