VPN 3002 Hardware Client User Guide

Encryption Protocols

Check the boxes for the encryption algorithms that the VPN 3002 SSH server can negotiate with a client

and use for session encryption. All algorithms are checked by default. You must check at least one

algorithm to enable a secure session. Unchecking all algorithms disables SSH.

3DES-168 = Triple-DES encryption with a 168-bit key. This option is the most secure but requires the

greatest processing overhead.

RC4-128 = RC4 encryption with a 128-bit key. This option provides adequate security and

performance.

DES-56 = DES encryption with a 56-bit key. This option is least secure but provides the greatest

export flexibility.

No Encryption = Connect without encryption. This option provides no security and is for testing

purposes only. It is not checked by default.
