Calculates the Hash of a character string according to a specific algorithm. You have the ability to calculate:
  • a simple hash.
  • a hash with message authentication.
Reminder: Hashing is used to summarize a file or a character string. This summary is called Hash.

Remarks

Notes

  • Two identical character strings 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.

HashString and UNICODE

  • Caution: The Hash functions operate on the bytes found in the character strings. For the same type of algorithm, the result will differ in UNICODE and in ANSI.
  • Multi-platform development: To use Hash of strings between several platforms (a hash generated in iOS and checked in Android or Windows for example), no Unicode string must be used. Indeed, the Unicode strings do not have the same format according to the platforms. In this case, we advise you to use strings in ANSI or UTF 8 format (and to convert the Unicode strings if necessary).
