Use Key –
This field allows you to choose which key to use for encryption.
Encryption Type –
This field allows you to specify whether to use a 64-bit or a 128-bit encryption key.
For a 128-bit encryption key use a 26-character hex key or a 13-character alphanumeric key. For 64-bit
encryption key, use a 10 character hex key or a 5 character alphanumeric key.
Encryption Formats –
The two formats used to develop encryption keys include hexadecimal or
alphanumeric as shown in Figure 3.13. Whichever format you choose, the key that you enter is used in
an encryption algorithm to encode the data that you send. Only another wireless card using the same
key can decode and receive the data. Hexadecimal values are composed of the NULL character (0x00),
0-9, A-F and a-f. Alphanumeric values are composed of all printable ASCII characters.
