How do you mathematically or logically prove that a secondary failover server contains the exact same password and secret key data as the primary server at any given moment?

To prove two servers match, you use a process called hashing. A hash is a digital fingerprint created by running data through a math formula that turns a file or password into a unique string of letters and numbers. If you change even one tiny dot in the original data, the resulting fingerprint changes completely. You ask b....
