C# 클래스 openHistorian.PerformanceTests.GuidSHA1Helper

This class is a helper class to quickly generate a strong hash code for a GUID type.
A strong hash function is important in Dictionary Lookups. If the hash is sufficently strong, a mod operation over the largest prime can be avoided, thus allowing for faster customized dictionary lookups. Method is the same as taking the last 4 bytes of a SHA1 hashsum, except zero is reserved and converted to 1.
