interfaces openvpn <vtunx> encryption <algorithm>

Specifies the encryption algorithm to be used within an OpenVPN tunnel.

set interfaces openvpn vtunx encryption algorithm
delete interfaces openvpn vtunx encryption
show interfaces openvpn vtunx encryption

The encryption algorithm is the Blowfish algorithm with 128-bit key.

vtunx
The identifier for the OpenVPN interface. This may be vtun0 to vtunx, where x is a non-negative integer.
algorithm
The encryption algorithm that is used within the OpenVPN tunnel. The algorithm is one of the following:

3des: DES algorithm with triple encryption

aes128: AES algorithm with 128-bit key

aes192: AES algorithm with 192-bit key

aes256: AES algorithm with 256-bit key

bf128: Blowfish algorithm with 128-bit key

bf256: Blowfish algorithm with 256-bit key

des: DES algorithm

The default algorithm is bf128.

Configuration mode

interfaces {
    openvpn vtunx {
        encryption algorithm
    }
}

Use this command to specify the encryption algorithm that is used within an OpenVPN tunnel.

Use the set form of this command to specify the encryption algorithm that is used within a tunnel.

Use the delete form of this command to remove the encryption algorithm that is used within a tunnel and return to the default algorithm, which is the Blowfish algorithm with 128-bit key.

Use the show form of this command to view the encryption algorithm that is used within a tunnel.
