Method Details

calcMessageAuthInput

static byte[] calcMessageAuthInput(RadiusPacket<?> packet,
 byte[] requestAuth)

getHmacMd5

static Mac getHmacMd5(String key)

verifyMessageAuth

default void verifyMessageAuth(String sharedSecret,
 byte[] requestAuth)
                        throws RadiusPacketException

Throws:

RadiusPacketException

computeMessageAuth

default byte[] computeMessageAuth(RadiusPacket<?> packet,
 String sharedSecret,
 byte[] requestAuth)

encodeMessageAuth

default T encodeMessageAuth(String sharedSecret,
 byte[] requestAuth)
                     throws RadiusPacketException

Creates packet with an encoded Message-Authenticator attribute.

Note: 'this' packet authenticator is ignored, only requestAuth param is used.

Parameters:

sharedSecret - shared secret

requestAuth - current packet auth if encoding request, otherwise corresponding request auth

Returns:

encoded copy of packet

Throws:

RadiusPacketException - packet validation exceptions
