Sample
stringPBKDF2Hash(textString)
Returns the PBKDF2 hash for specified text. This method is preferred above the old MD5 hash for enhanced security. It uses a default of 9999 iterations. The string that is returned can only be used in the utils.validatePBKDF2Hash(password,thisReturnValue) to check if this hash is a result of that password. This will always be false: utils.stringPBKDF2Hash("test") == utils.stringPBKDF2Hash("test"). Because for the same string in multiply calls it will not generate the same hash. So you can only check it like this: utils.validatePBKDF2Hash("test",utils.stringPBKDF2Hash("test"))
NOTE: PBKDF2 is the key hash function for the PKCS (Public-Key Cryptography) standard, for more info see: http://en.wikipedia.org/wiki/PBKDF2
Parameters
String textString the text to process
Returns: String the resulting hashString
Sample
stringPBKDF2Hash(textString, iterations)
Returns the PBKDF2 hash for specified text. This method is preferred above the old MD5 hash for enhanced security. From Servoy 2024.3.1 on this method will use SHA256 (HmacSHA256) as the Hash Algorithm. Before that it did use SHA1 (HmacSHA1) as the Hash Algorithm, this does result in the a different length of the hash. The total hash length (including interations of 9999) for SHA256 is 87 that was 63. So you need to make sure you can store at least 87 characters in your database. (but make sure you can handle more for future updates)
NOTE: PBKDF2 is the key hash function for the PKCS (Public-Key Cryptography) standard, for more info see: http://en.wikipedia.org/wiki/PBKDF2

validatePBKDF2Hash(password, hash)
Validates the given password against the given hash. The hash should be generated by one of the stringPBKDF2Hash(password [,iteration]) functions.
