This page lists all compiler options with which implementation e/hc-256/200701 of hc256 was tested.

The progress bar shows the relative number of successes, fails, and errors across all tested hosts:

  • Success. The constant-time checker didn't find any cases where the execution time of the tested code depends on secret data.
  • Fail. The execution time of the tested code depends on secret data.
  • Error.

Errors can have multiple causes:
  • The constant-time checker encountered an error and couldn't be completed.
  • Valgrind found memory issues, but none of them are related to constant-time checks.
  • The constant-time checker timed out after 6 minutes.
  • The tested code produced invalid results. More details can be found near the start of the output file. Example:
    crypto_aead_decrypt returns nonzero 

The absolute number of successes, fails, and errors is shown to the left of the progress bar.
