Functions

func GenerateSeed

func GenerateSeed(length uint16) ([]byte, error)

GenerateSeed returns a cryptographically secure random seed that can be used as the input for the further usage.

The length is in bytes and it must be between 16 and 256 (128 to 1024 bits). The default length is 32 (256 bits) as defined by the DefaultSeedLength constant.
