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.
  • a hash obtained with a key derivation function that takes a salt as parameter (PBKDF2).
    PHP Not available.
Reminder Hashing is used to produce a condensed summary of a file or character string. This summary is called Hash.
Ejemplo
WEBDEV - Código ServidorAjax 
// Calculate the Hash of the "C:\Temp\File.txt" file
HashMyFile is string 
HashMyFile = HashFile(HA_MD5_128, "C:\Temp\File.txt")

// Process on the file
// ...

// Checks whether the file was modified
IF HashCheckFile(HA_MD5_128, "C:\Temp\File.txt", ...
		HashMyFile) = False THEN
	Info("The file was modified.")
END
