HashCheckFile (Function)
In French: HashVérifieFichier
Checks the Hash of a file for a specific type of algorithm. You have the ability to check:
  • a simple hash.
  • a hash with message authentication.
Reminder: The hashing is used to summarize a file or a character string. This summary is called Hash.
