Usage

% provendb-oracle validate --help
Validate a rowId against the most recent proof.

USAGE
  $ provendb-oracle validate

OPTIONS
  -v, --verbose      increased logging verbosity
  --config=config    config file location
  --output=output    output file for proof
  --proofId=proofId  proofId to validate
  --rowId=rowId      row ID to validate

DESCRIPTION
  Validate compares the data in the database (or in the flashback archive) to the
  digital signature (hash value) that was created when the row was anchored.  It then
  confirms that the hashes match and that the hash is included in the blockchain anchor.

  Validate generates a proof file which contains the row data and anchor information.  This
  proof file can serve as an independent proof of the data.

Arguments

Argument	Description
--config	Configuration file which contains Oracle and provend DB configuration see Configuration file Reference
--output	file to contain cryptographic proof validation
--proofId	Validate the provided proof Id
--rowId	Validate the provided rowId
--generateCertificate	Include a PDF "certificate" with each row proof. This is a human-readable version of the JSON cryptographic proof for that row

Example

% provendb-oracle validate --config=conf/p4o.yaml --proofId=t1fLbeVECCJ0uFXMr2t76t --output=myproof.proof
