Method Detail

signMessage

public static void signMessage(Message message,
               KEYRecord key,
               java.security.PrivateKey privkey,
               SIGRecord previous)
                        throws DNSSEC.DNSSECException

Sign a message with SIG(0). The DNS key and private key must refer to the same underlying cryptographic key.

Parameters:

message - The message to be signed

key - The DNSKEY record to use as part of signing

privkey - The PrivateKey to use when signing

previous - If this message is a response, the SIG(0) from the query

Throws:

DNSSEC.DNSSECException

verifyMessage

public static void verifyMessage(Message message,
                 byte[] b,
                 KEYRecord key,
                 SIGRecord previous)
                          throws DNSSEC.DNSSECException

Verify a message using SIG(0).

Parameters:

message - The message to be signed

b - An array containing the message in unparsed form. This is necessary since SIG(0) signs the message in wire format, and we can't recreate the exact wire format (with the same name compression).

key - The KEY record to verify the signature with.

previous - If this message is a response, the SIG(0) from the query

Throws:

DNSSEC.DNSSECException
