nsrlc (NSRL Client) is a command line application designed to work in conjunction with an nsrls server instance. The client uses the servers HTTP API service to lookup large sets of hash data.

By default the nsrlc application sends the hashes in batches of 1000. The number of hashes in a batch is configured via the -b command line parameter

The application outputs directly to a file. The output format can be defined by the command line parameters. The options for the output format are:

• i: Outputs only the identified hashes
• u: Outputs only the unidentified hashes
• a: Outputs both the identified and unidentified hashes, along with a status column
