libsodium.ResourceLimits

Enumeration

 Protected Enum ResourceLimits
     Sensitive
     Moderate
     Interactive

Remarks

These are the possible resource requirements for Argon2i and scrypt based hashing and key stretching.

Password hashing and key stretching are susceptible to attacks that use relatively inexpensive custom hardware. To mitigate this attack vector, derivation and hashing can be done with a variable amount of deliberate "slowness" in the operation.

The members of this enum correspond to the three main levels of slowness:

Name	Comment
Sensitive	The slowest and most secure option.
Moderate	A middle ground between secure and fast.
Interactive	Fastest but least secure.
