func Derivate ¶

func Derivate(
	size int,
	hashString string,
	secret []byte,
	salt []byte,
	info []byte) ([]byte, error)

Derivate derives a new key from the given secret.

It returns a key with the specified length and an error which is nil if nothing bad happened.

You need to provide a string specifying the hash function (supported:SHA512, SHA256). You also need to provide three byte slices: the secret, the salt, the info. They can also be nil.
