validate command
Validate a proof
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
