Field Details

serial

private long serial

A 32-bit unsigned integer in network byte order. It is the serial number from the zone's SOA record (RFC 1035, Section 3.3.13]) for which the zone digest was generated.

scheme

private int scheme

An 8-bit unsigned integer that identifies the methods by which data is collated and presented as input to the hashing function.

See Also:

• ZoneMDRecord.Scheme

hashAlgorithm

private int hashAlgorithm

An 8-bit unsigned integer that identifies the cryptographic hash algorithm used to construct the digest.

See Also:

• ZoneMDRecord.Hash

digest

private byte[] digest

A byte array containing the output of the hash algorithm. The length is determined by

invalid reference

#getHashAlgorithm()

.
