BCrypt

v3.0.1+34 Public

BCrypt Module for the ColdBox Framework Build Status

BCrypt's primary usage would be for the secure hashing of passwords. The hashing method provides a high level of security, but also makes it too slow use as a simple digest. It is also not reversible, and therefore is not suitable for encrypting transmission data.

More information about BCrypt:

Installation

Install the module via Commandbox, which will ensure all dependencies are installed as well:

box install bcrypt

Requirements

  • ColdBox Framework 5.0+
  • cbjavaloader module ( automatically installed as a dependency by Forgebox )

BCrypt.jar

A compiled version (0.4) of jBCrypt is listed as a dependency for the test harness. You can update the version by following the steps below.

  1. Visit http://www.mindrot.org/projects/jBCrypt/.
  2. Copy the link to the latest version
  3. Update the test-harness/box.json dependency with the correct version information
  4. Run box install from within the test-harness directory
  5. Execute ant -f test-harness/resources/jBCrypt-[version number]/build.xml and move the generated jbcrypt.jar file to models/lib

Usage

BCrypt WireBox Mapping

This module registers a wirebox mapping to the Bcrypt singleton, [email protected], which you may inject or instantiate in your componets:

// Long Format
property name="BCrypt" inject="[email protected]";

// Module Alias Shortcut
property name="BCrypt" inject="@BCrypt";

or via getInstance() ( a ColdBox framework supertype method ) inside your handlers, views, interceptors, etc.

getInstance( "[email protected]" )
getInstance( "@BCrypt" )

BCrypt Mixins

We have also created three mixin helpers that will be injected to all your handlers, interceptors, layouts and views: bcryptHash(), bcryptCheck(), bcryptSalt()

/**
 * Hashes an incoming input string according to work factor and salt
 *
 * @password The input password to encrypt
 * @workFactor Optional work factor
 *
 * @return The bcrypted password
 */
string function bcryptHash(
	required string password,
	workFactor,
	salt
)

/**
 * Check if the incoming candidate is the same as a bcrypthash, usually the best check for comparing them.
 *
 * @candidate The plain text string to compare against the encrypted hash
 * @bCryptHash The bCrypt hash to compare it to
 *
 * @return True - if the match, false if they dont!
 */
boolean function bcryptCheck( required string candidate, required string bCryptHash )

/**
 * Generates a salt for you.
 *
 * @workFactor The workfactor to use for the salt, by default we use the one in the settings
 */
string function bcryptSalt( workFactor )

Generating a password hash

The hashed password should be persisted so candidate passwords (submitted from login) can be checked against.

var hashedPassword = getInstance( "BCrypt" ).hashPassword( plaintextPassword );

Checking a password hash

The plaintextPasswordCandidate is the password the user submits for authentication. The hashed password is retrieved for the user being authenticated.

var isSamePassword = getInstance( "BCrypt" ).checkPassword( plaintextPasswordCandidate, hashedPassword );

Using a Custom Salt

Internally we generate a salt for you according to the default work factor. You can however, alter this and pass in your own salt:

var hashedPassword = getInstance( "BCrypt" ).hashPassword( 
	password : plaintextPassword,
	salt : mySalt
);

Configuring WorkFactor

WorkFactor is an input to BCrypt that controls how long (generally) it takes to hash a password. The module sets a default value of 12. You should experiment to find the optimal value for your environment. It should take as long as possible to hash a password without being burdensome to your users on login. Half a second to a full second is generally a good target to shoot for.

You can also set the workFactor on a per-call basis by passing it in as a second parameter to the hashPassword method like so:

var hashedPassword = getInstance( "@BCrypt" ).hashPassword( plaintextPassword, 7 );

BCrypt Settings

You may override the default work factor by creating a BCrypt settings struct in your ColdBox.cfc under the moduleSettings struct:

moduleSettings = {
	bcrypt = {
		workFactor = 15
	}
};
