Calculates the Hash of a file according to a specific algorithm. You have the ability to calculate:
  • a simple hash.
  • a hash with message authentication.
  • a hash obtained with a key derivation function that takes a salt as parameter (PBKDF2).

Reminder Hashing is used to produce a condensed summary of a file or character string. This summary is called Hash.
Caution: Result may contain characters that cannot be displayed. If you want to get a string with the hexadecimal representations of bytes (to use it in a REST or SOAP API, for example) you can use BufferToHexa with the NoGrouping constant on the result buffer.

// Calculate the Hash of two files
Hash1 is Buffer = HashFile(HA_MD5_128, "C:\My files\FileA.txt")
Hash2 is Buffer = HashFile(HA_MD5_128, "D:\My files\FileB.txt")
// Compare the two Hash
IF Hash1 = Hash2 THEN Info("The two files are identical.")

<Length>: Integer
Length of the derived key. By default, corresponds to the size of the key generated by the pseudo-random function. This length is technically unbounded but due to the algorithm, it is limited to (2^32 - 1) * (output length of the algorithm used by PBKDF2).

Notes

  • Two files with an identical content will have, for the same type of algorithm, two identical Hashes.
  • The result of the Hash may contain non-displayable characters. These characters will not be visible when using Info or Trace for example.
