Description
This checker detects the usage of
scrypt.Keywith anNparameter (CPU/memory cost parameter) less than 32768. The scrypt algorithm is designed to be memory-hard, making it resistant to brute-force attacks, especially those using custom hardware. A lowNparameter reduces the memory and CPU cost, making it easier for attackers to crack passwords. This checker is flagged as a security warning to ensurescryptis configured with a sufficiently highNparameter.Recommendation
Use an N parameter of 32768 or higher when calling
scrypt.Key.
