Field Detail

algorithm

public final DnssecConstants.SignatureAlgorithm algorithm

The cryptographic algorithm used to create the signature. If MiniDNS isn't aware of the signature algorithm, then this field will be null.

See Also:

algorithmByte

algorithmByte

public final byte algorithmByte

The byte value of the cryptographic algorithm used to create the signature.

digest

protected final byte[] digest

The digest build from a DNSKEY.

digestType

public final DnssecConstants.DigestAlgorithm digestType

The algorithm used to construct the digest. If MiniDNS isn't aware of the digest algorithm, then this field will be null.

See Also:

digestTypeByte

digestTypeByte

public final byte digestTypeByte

The byte value of algorithm used to construct the digest.

keyTag

public final int keyTag

The key tag value of the DNSKEY RR that validates this signature.
