Method Signature

 Function DeriveKey(KeyLength As Int32, Salt As MemoryBlock, Limits As libsodium.ResourceLimits, HashAlgorithm As Int32 = libsodium.Password.ALG_ARGON2) As MemoryBlock

Parameters

Name	Type	Comment
KeyLength	Int32	The length, in bytes, of the requested key.
Salt	MemoryBlock	A random salt for the key derivation algorithm.
Limits	ResourceLimits	A member of the ResourceLimits enumeration.
HashAlgorithm	Int32	Optional. Either ALG_ARGON2 (default) or ALG_SCRYPT.

Return value

Unpredictable bytes suitable to be used as a cryptographic key of the requested length.

Remarks

Computes a key of the specified KeySize using the Password, Salt, Limits, and HashAlgorithm.
