Constructor Detail

SIG0Signer

public SIG0Signer(int algorithm,
                  PrivateKey privateKey,
                  Name name,
                  int keyFootprint)

Creates a new SIG(0) signer object.

Parameters:

algorithm - usually DNSSEC.RSAMD5, DNSSEC.DSA, or DNSSEC.RSASHA1

privateKey - signing key (must match algorithm)

name - the name of the key

keyFootprint - the key tag

SIG0Signer

public SIG0Signer(int algorithm,
                  PrivateKey privateKey,
                  Name name,
                  PublicKey publicKey)

Creates a new SIG(0) signer object. This is the same as the other constructor, except that the key tag is calculated automatically from the given public key.
