This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. scrypt.Key derives deterministic key bytes matching the specified key length
  2. scrypt.Key produces different derived keys for different passwords with identical parameters
  3. scrypt.Key produces different derived keys for different salts with identical parameters
  4. scrypt.Key produces different derived keys when cost parameter N is varied
  5. scrypt.Key produces different derived keys when block size parameter r is varied
  6. scrypt.Key produces different derived keys when parallelization parameter p is varied
  7. scrypt.Key returns an error when N is not a power of 2 or less than or equal to 1
  8. scrypt.Key returns an error when parameters r and p are too large
