public final class SealAttributes extends SmartObject<SealAttributes> {

The unique identifier for the notary key that was used to generate the signature.
    public Tag notaryKeyId;

A base 32 encoding of the SHA256 hash of the byte encoding for the public verification key associated with the signing key used to generate the signature.
    public String sha256VerificationKeyHash;

The date and time that the document was notarized.
    public DateTime timestamp;

The type of document that this seal notarizes.
    public String documentType;

A base 32 encoding of the bytes that were generated as a signature of the document. The signature must be generated using the following steps:
  1. Format the document as a string.
  2. Extract the characters of the string into a "UTF-8" based byte array.
  3. Generate the signature bytes for that array using the algorithm specified in the Watermark.
  4. Encode the signature bytes as a base 32 string using the craterdog.utils.Base32Utils class.
    public String documentSignature;

The default constructor ensures that the custom attribute types (like tags) will be formatted correctly when printed.
