Field Detail

notaryKeyId

public craterdog.primitives.Tag notaryKeyId

The unique identifier for the notary key that was used to generate the signature.

sha256VerificationKeyHash

public String sha256VerificationKeyHash

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.

timestamp

public org.joda.time.DateTime timestamp

The date and time that the document was notarized.

documentType

public String documentType

The type of document that this seal notarizes.

documentSignature

public String documentSignature

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.
