ComputeMAC creates a message authentication code (MAC), sometimes known as a "tag", which is a short piece of information used for authenticating a message, by using some deterministic data (the traditional "key" concept) which authenticates the origin of the message, where the deterministic data (key) serves to regenerate the expected MAC (tag) for the original message.

StringsSliceContainsString checks if a string is contained in some member of the slice.

StringsSliceContains checks if a string is equal to some member in the slice.

StringToStringsArray splits the string around each instance of one or more consecutive white space characters.
