HashCheckString (Function)
In french: HashVérifieChaîne
Checks the Hash of a character string for a specific type of algorithm. You have the ability to check:
  • 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.

  • HA_HMAC_SHA_160
  • HA_HMAC_SHA_256
  • HA_HMAC_SHA_384
  • HA_HMAC_SHA_512

Remarks:
  • These hash algorithms are not allowed in Internet Explorer.
  • These hash algorithms are not allowed in Edge.
<String>: Character string (with quotes)
String for which the Hash will be checked.
<Hash>: Character string (with quotes)
Hash of string to check. This Hash must be the result of HashString previously called for <String> on <Type of algorithm>.
<Secret key>: Character string (between quotes) or Integer
Authentication key of message. This key must be identical to the one used to calculate the Hash.
<WLanguage procedure>: Procedure name
Name of the WLanguage procedure ("callback") called when hashing. This procedure is used to get the hash result. See Procedure used by HashCheckString for more details.

HashCheckString and UNICODE

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).
