Utils

(utils)

Overview

The Utils scripting object provides a range of utility methods for data transformation, formatting, and validation. It includes functionality for handling Base64 encoding and decoding, byte array manipulation, and string transformations such as escaping markup, formatting, and hashing. This makes it a versatile tool for managing data in different formats.

Key methods include base64ToBytes, which converts Base64-encoded strings to byte arrays, and bytesToBase64, which performs the reverse operation. The dateFormat method allows dates to be formatted based on specified patterns, with support for custom timezones and locales. Similarly, numberFormat enables precise number formatting, including locale-specific options.

Advanced string operations such as stringReplace, stringFormat, and stringTrim are complemented by security-focused methods like stringMD5HashBase16 and stringPBKDF2Hash, providing robust options for hashing and validation. For example, validatePBKDF2Hash ensures that a given password matches a hash, supporting modern cryptographic standards like SHA256.

The object also facilitates Unicode character conversion, checks for related records using hasRecords, and parses strings into date objects with parseDate, offering rich functionality for varied use cases.

stringMD5HashBase64(textString)

Returns the md5 hash (encoded as base64) for specified text.

NOTE: MD5 (Message-Digest Algorythm 5) is a hash function with a 128-bit hash value, for more info see: http://en.wikipedia.org/wiki/MD5

Parameters

• String textString the text to process

Returns: String the resulting hashString

Sample

var hashed_password = utils.stringMD5HashBase64(user_password)

stringMiddle(text, i_start, i_size)

Returns a substring from the original string.

Parameters

• String text the text to process

• Number i_start the start index to work from

• Number i_size the size of the text to return

Returns: String the result text string

Sample

//returns 'his'
var retval = utils.stringMiddle('this is a test',2,3);

stringMiddleWords(text, i_start, numberof_words)

Returns a substring from the original string.

Parameters

• String text to process

• Number i_start start word index

• Number numberof_words the word count to return

Returns: String the string with number of words form the left and

Sample

//returns 'is a'
var retval = utils.stringMiddleWords('this is a test',2,2);

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

var hashed_password = utils.stringPBKDF2Hash(user_password)

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

Parameters

• String textString the text to process

Returns: String the resulting hashString

stringPosition(textString, toSearchFor, i_start, i_occurrence)

Returns the position of the string to search for, from a certain start position and occurrence.

Parameters

• String textString the text to process

stringReplaceTags(text, scriptable)

Returns the text with %%tags%% replaced, based on provided record or foundset or form.

Parameters

• String text the text tags to work with

• Object scriptable the javascript object or foundset,record,form to be used to fill in the tags

Returns: String the text with replaced tags

Sample

//Next line places a string in variable x, whereby the tag(%%TAG%%) is filled with the value of the database column 'company_name' of the selected record.
var x = utils.stringReplaceTags("The companyName of the selected record is %%company_name%% ", foundset)
//var otherExample = utils.stringReplaceTags("The amount of the related order line %%amount%% ", order_to_orderdetails);
//var recordExample = utils.stringReplaceTags("The amount of the related order line %%amount%% ", order_to_orderdetails.getRecord(i);
//Next line places a string in variable y, whereby the tag(%%TAG%%) is filled with the value of the form variable 'x' of the form named 'main'.
//var y = utils.stringReplaceTags("The value of form variable is %%x%% ", forms.main);
//The next sample shows the use of a javascript object
//var obj = new Object();//create a javascript object
//obj['x'] = 'test';//assign an named value
//var y = utils.stringReplaceTags("The value of object variable is %%x%% ", obj);//use the named value in a tag

validatePBKDF2Hash(password, hash)

Parameters

• String password the password to test against

• String hash the hash the password needs to validate to.

Returns: Boolean true if his hash is valid for that password

Sample

if (utils.validatePBKDF2Hash(user_password, hashFromDb)) {
   // logged in
}
