AES Encryption
When encryption is enabled in a network, all data sent over the air is protected from eavesdropping and can only be read by
radios sharing the same Encryption Key. Encryption must be enabled in each radio in a network. The encryption key is 256
bits long and is entered as string or a hexadecimal number. For maximum security the key chosen should be one that is
difficult for an intruder to guess.
Once written into the radio using the programmer, it is not possible to read the encryption key so care must be taken to
record the key in a safe place.
Encryption Key: String
For a string type of key, use up to a maximum of 64 printable characters. Please note that the key is case sensitive.
Some examples are:
TRIO2012
Murray River Region
Encryption Key: Hexadecimal Number
Hexadecimal numbers can have a value of 0 to 15 and are represented by 0-9 and A, B, C, D, E or F.
A hexadecimal key begins with 0x and has up to 64 digits following.
Use an even number of hexadecimal digits.
Some examples are:
0x1234
0x123456789ABCDE
0x11111111222222223333333344444444 up to 64 digits
