+# OWASP Enterprise Security API (ESAPI) Properties file -- PRODUCTION Version
+#
+# This file is part of the Open Web Application Security Project (OWASP)
+# Enterprise Security API (ESAPI) project. For details, please see
+# http://www.owasp.org/index.php/ESAPI.
+#
+# Copyright (c) 2008,2009 - The OWASP Foundation
+#
+# DISCUSS: This may cause a major backwards compatibility issue, etc. but
+#		   from a name space perspective, we probably should have prefaced
+#		   all the property names with ESAPI or at least OWASP. Otherwise
+#		   there could be problems is someone loads this properties file into
+#		   the System properties.  We could also put this file into the
+#		   esapi.jar file (perhaps as a ResourceBundle) and then allow an external
+#		   ESAPI properties be defined that would overwrite these defaults.
+#		   That keeps the application's properties relatively simple as usually
+#		   they will only want to override a few properties. If looks like we
+#		   already support multiple override levels of this in the
+#		   DefaultSecurityConfiguration class, but I'm suggesting placing the
+#		   defaults in the esapi.jar itself. That way, if the jar is signed,
+#		   we could detect if those properties had been tampered with. (The
+#		   code to check the jar signatures is pretty simple... maybe 70-90 LOC,
+#		   but off course there is an execution penalty (similar to the way
+#		   that the separate sunjce.jar used to be when a class from it was
+#		   first loaded). Thoughts?

+# way up to the root directory of the file system.  Note that if you are using
+# file-based implementations, that some files may need to be read-write as they
+# get updated dynamically.
+#
+# Before using, be sure to update the MasterKey and MasterSalt as described below.
+# N.B.: If you had stored data that you have previously encrypted with ESAPI 1.4,
+#		you *must* FIRST decrypt it using ESAPI 1.4 and then (if so desired)
+#		re-encrypt it with ESAPI 2.0. If you fail to do this, you will NOT be
+#		able to decrypt your data with ESAPI 2.0.

+#    CipherText cipherText =
+#		ESAPI.encryptor().encrypt(new PlainText("Secret message")); // Preferred
+#

+# ESAPI Encryption
+#
+# The ESAPI Encryptor provides basic cryptographic functions with a simplified API.
+# To get started, generate a new key using java -classpath esapi.jar org.owasp.esapi.reference.crypto.JavaEncryptor
+# There is not currently any support for key rotation, so be careful when changing your key and salt as it
+# will invalidate all signed, encrypted, and hashed data.
+#
+# WARNING: Not all combinations of algorithms and key lengths are supported.
+# If you choose to use a key length greater than 128, you MUST download the
+# unlimited strength policy files and install in the lib directory of your JRE/JDK.
+# See http://java.sun.com/javase/downloads/index.jsp for more information.
+#
+# Backward compatibility with ESAPI Java 1.4 is supported by the two deprecated API
+# methods, Encryptor.encrypt(String) and Encryptor.decrypt(String). However, whenever
+# possible, these methods should be avoided as they use ECB cipher mode, which in almost
+# all circumstances a poor choice because of it's weakness. CBC cipher mode is the default
+# for the new Encryptor encrypt / decrypt methods for ESAPI Java 2.0.  In general, you
+# should only use this compatibility setting if you have persistent data encrypted with
+# version 1.4 and even then, you should ONLY set this compatibility mode UNTIL
+# you have decrypted all of your old encrypted data and then re-encrypted it with
+# ESAPI 2.0 using CBC mode. If you have some reason to mix the deprecated 1.4 mode
+# with the new 2.0 methods, make sure that you use the same cipher algorithm for both
+# (256-bit AES was the default for 1.4; 128-bit is the default for 2.0; see below for
+# more details.) Otherwise, you will have to use the new 2.0 encrypt / decrypt methods
+# where you can specify a SecretKey. (Note that if you are using the 256-bit AES,
+# that requires downloading the special jurisdiction policy files mentioned above.)
+#
+#		***** IMPORTANT: Do NOT forget to replace these with your own values! *****
+# To calculate these values, you can run:
+#		java -classpath esapi.jar org.owasp.esapi.reference.crypto.JavaEncryptor
+#
+#Encryptor.MasterKey=
+#Encryptor.MasterSalt=
+
+# Provides the default JCE provider that ESAPI will "prefer" for its symmetric
+# encryption and hashing. (That is it will look to this provider first, but it
+# will defer to other providers if the requested algorithm is not implemented
+# by this provider.) If left unset, ESAPI will just use your Java VM's current
+# preferred JCE provider, which is generally set in the file
+# "$JAVA_HOME/jre/lib/security/java.security".
+#
+# The main intent of this is to allow ESAPI symmetric encryption to be
+# used with a FIPS 140-2 compliant crypto-module. For details, see the section
+# "Using ESAPI Symmetric Encryption with FIPS 140-2 Cryptographic Modules" in
+# the ESAPI 2.0 Symmetric Encryption User Guide, at:
+# http://owasp-esapi-java.googlecode.com/svn/trunk/documentation/esapi4java-core-2.0-symmetric-crypto-user-guide.html
+# However, this property also allows you to easily use an alternate JCE provider
+# such as "Bouncy Castle" without having to make changes to "java.security".
+# See Javadoc for SecurityProviderLoader for further details. If you wish to use
+# a provider that is not known to SecurityProviderLoader, you may specify the
+# fully-qualified class name of the JCE provider class that implements
+# java.security.Provider. If the name contains a '.', this is interpreted as
+# a fully-qualified class name that implements java.security.Provider.
+#
+# NOTE: Setting this property has the side-effect of changing it in your application
+#       as well, so if you are using JCE in your application directly rather than
+#       through ESAPI (you wouldn't do that, would you? ;-), it will change the
+#       preferred JCE provider there as well.
+#
+# Default: Keeps the JCE provider set to whatever JVM sets it to.
+Encryptor.PreferredJCEProvider=
+
+# AES is the most widely used and strongest encryption algorithm. This
+# should agree with your Encryptor.CipherTransformation property.
+# By default, ESAPI Java 1.4 uses "PBEWithMD5AndDES" and which is
+# very weak. It is essentially a password-based encryption key, hashed
+# with MD5 around 1K times and then encrypted with the weak DES algorithm
+# (56-bits) using ECB mode and an unspecified padding (it is
+# JCE provider specific, but most likely "NoPadding"). However, 2.0 uses
+# "AES/CBC/PKCSPadding". If you want to change these, change them here.
+# Warning: This property does not control the default reference implementation for
+#		   ESAPI 2.0 using JavaEncryptor. Also, this property will be dropped
+#		   in the future.
+# @deprecated
+Encryptor.EncryptionAlgorithm=AES
+#		For ESAPI Java 2.0 - New encrypt / decrypt methods use this.

+# related key attacks than is 256-bit AES. Use '_' to use default key size
+# for cipher algorithms (where it makes sense because the algorithm supports
+# a variable key size). Key length must agree to what's provided as the

+# Because 2.0 uses CBC mode by default, it requires an initialization vector (IV).
+# (All cipher modes except ECB require an IV.) There are two choices: we can either
+# use a fixed IV known to both parties or allow ESAPI to choose a random IV. While
+# the IV does not need to be hidden from adversaries, it is important that the
+# adversary not be allowed to choose it. Also, random IVs are generally much more
+# secure than fixed IVs. (In fact, it is essential that feed-back cipher modes
+# such as CFB and OFB use a different IV for each encryption with a given key so
+# in such cases, random IVs are much preferred. By default, ESAPI 2.0 uses random
+# IVs. If you wish to use 'fixed' IVs, set 'Encryptor.ChooseIVMethod=fixed' and
+# uncomment the Encryptor.fixedIV.
+#
+# Valid values:		random|fixed|specified		'specified' not yet implemented; planned for 2.1
+Encryptor.ChooseIVMethod=random
+# If you choose to use a fixed IV, then you must place a fixed IV here that
+# is known to all others who are sharing your secret key. The format should
+# be a hex string that is the same length as the cipher block size for the
+# cipher algorithm that you are using. The following is an *example* for AES
+# from an AES test vector for AES-128/CBC as described in:
+# NIST Special Publication 800-38A (2001 Edition)
+# "Recommendation for Block Cipher Modes of Operation".

+# Whether or not CipherText should use a message authentication code (MAC) with it.
+# This prevents an adversary from altering the IV as well as allowing a more
+# fool-proof way of determining the decryption failed because of an incorrect
+# key being supplied. This refers to the "separate" MAC calculated and stored
+# in CipherText, not part of any MAC that is calculated as a result of a
