AuthKey() [1/3]

isc::dhcp::AuthKey::AuthKey

(

const std::vector< uint8_t > &

key

)

Constructor.

Constructor for assigning auth keys in host reservation. Ensures the key length is not greater than 16 bytes.

Parameters

key	auth key in binary to be stored.

setAuthKey() [1/2]

void isc::dhcp::AuthKey::setAuthKey

(

const std::string &

)

Set auth key value from hexadecimal.

Set the key value. If the size is greater than 16 bytes, we resize to 16 bytes.

Parameters

key	auth key in hexadecimal to be stored.

Exceptions

BadValue

if the string is not a valid hexadecimal encoding, for instance has a not hexadecimal or odd number of digits.
