flags

public final byte flags

Bitmap of flags: FLAG_OPT_OUT.

iterations

public final int iterations

The number of iterations the hash algorithm is applied.

salt

public final byte[] salt

The salt appended to the next owner name before hashing.

nextHashed

public final byte[] nextHashed

The next hashed owner name in hash order.

types
