#
# 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?

#
# If true, then print all the ESAPI properties set here when they are loaded.
# If false, they are not printed. Useful to reduce output when running JUnit tests.
# If you need to troubleshoot a properties related problem, turning this on may help.
# This is 'false' in the src/test/resources/.esapi version. It is 'true' by
# default for reasons of backward compatibility with earlier ESAPI versions.

# ESAPI is designed to be easily extensible. You can use the reference implementation
# or implement your own providers to take advantage of your enterprise's security
# infrastructure. The functions in ESAPI are referenced using the ESAPI locator, like:
#
#    String ciphertext =
#		ESAPI.encryptor().encrypt("Secret message");   // Deprecated in 2.0
#    CipherText cipherText =
#		ESAPI.encryptor().encrypt(new PlainText("Secret message")); // Preferred
#
# Below you can specify the classname for the provider that you wish to use in your
# application. The only requirement is that it implement the appropriate ESAPI interface.
# This allows you to switch security implementations in the future without rewriting the
# entire application.

#===========================================================================
# 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.
#
#		***** 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.
# 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.
Encryptor.CipherTransformation=AES/CBC/PKCS5Padding

# Applies to ESAPI 2.0 and later only!
# Comma-separated list of cipher modes that provide *BOTH*
# confidentiality *AND* message authenticity. (NIST refers to such cipher
# modes as "combined modes" so that's what we shall call them.) If any of these
# cipher modes are used then no MAC is calculated and stored
# in the CipherText upon encryption. Likewise, if one of these
# cipher modes is used with decryption, no attempt will be made
# to validate the MAC contained in the CipherText object regardless
# of whether it contains one or not. Since the expectation is that
# these cipher modes support support message authenticity already,
# injecting a MAC in the CipherText object would be at best redundant.
#
# Note that as of JDK 1.5, the SunJCE provider does not support *any*
# of these cipher modes. Of these listed, only GCM and CCM are currently
# NIST approved. YMMV for other JCE providers. E.g., Bouncy Castle supports
# GCM and CCM with "NoPadding" mode, but not with "PKCS5Padding" or other
# padding modes.
Encryptor.cipher_modes.combined_modes=GCM,CCM,IAPM,EAX,OCB,CWC

# Applies to ESAPI 2.0 and later only!
# Additional cipher modes allowed for ESAPI 2.0 encryption. These
# cipher modes are in _addition_ to those specified by the property
# 'Encryptor.cipher_modes.combined_modes'.
# DISCUSS: Better name?
Encryptor.cipher_modes.additional_allowed=CBC

# Default key size to use for cipher specified by Encryptor.EncryptionAlgorithm.
# Note that this MUST be a valid key size for the algorithm being used
# (as specified by Encryptor.EncryptionAlgorithm). So for example, if AES is used,
# it must be 128, 192, or 256. If DESede is chosen, then it must be either 112 or 168.
#
# Note that 128-bits is almost always sufficient and for AES it appears to be more
# somewhat more resistant to related key attacks than is 256-bit AES.)
#
# Defaults to 128-bits if left blank.
#
# NOTE: If you use a key size > 128-bits, then you MUST have the JCE Unlimited
#       Strength Jurisdiction Policy files installed!!!
#
Encryptor.EncryptionKeyLength=128

# This is the _minimum_ key size (in bits) that we allow with ANY symmetric
# cipher for doing encryption. (There is no minimum for decryption.)
#
# Generally, if you only use one algorithm, this should be set the same as
# the Encryptor.EncryptionKeyLength property.
Encryptor.MinEncryptionKeyLength=128

# Because 2.x uses CBC mode by default, it requires an initialization vector (IV).
# (All cipher modes except ECB require an IV.) Previously there were two choices: we can either
# use a fixed IV known to both parties or allow ESAPI to choose a random IV. The
# former was deprecated in ESAPI 2.2 and removed in ESAPI 2.3. It was not secure
# because the Encryptor (as are all the other major ESAPI components) is a
# singleton and thus the same IV would get reused each time. It was not a
# well-thought out plan. (To do it correctly means we need to add a setIV() method
# and get rid of the Encryptor singleton, thus it will not happen until 3.0.)
# However, while the IV does not need to be hidden from adversaries, it is important that the
# adversary not be allowed to choose it. Thus for now, ESAPI just chooses a random IV.
# Originally there was plans to allow a developer to provide a class and method
# name to define a custom static method to generate an IV, but that is just
# trouble waiting to happen. Thus in effect, the ONLY acceptable property value
# for this property is "random". In the not too distant future (possibly the
# next release), I will be removing it, but for now I am leaving this and
# checking for it so a ConfigurationException can be thrown if anyone using
# ESAPI ignored the deprecation warning message and still has it set to "fixed".
#
# Valid values:		random
Encryptor.ChooseIVMethod=random


# 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
# "combined mode" cipher mode.
#
# If you are using ESAPI with a FIPS 140-2 cryptographic module, you *must* also
# set this property to false. That is because ESAPI takes the master key and
# derives 2 keys from it--a key for the MAC and a key for encryption--and
# because ESAPI is not itself FIPS 140-2 verified such intermediary aterations
# to keys from FIPS approved sources would have the effect of making your FIPS
# approved key generation and thus your FIPS approved JCE provider unapproved!

# the MAC, mostly to keep the overall size at a minimum.)
#
# Currently supported choices for JDK 1.5 and 1.6 are:
#	HmacSHA1 (160 bits), HmacSHA256 (256 bits), HmacSHA384 (384 bits), and
#	HmacSHA512 (512 bits).

# This is a workaround to make sure that a commit to address GitHub issue #509
# doesn't accidentally break someone's production code. So essentially what we
# are doing is to reverting back to the previous possibly buggy (by
# documentation intent at least), but, by now, expected legacy behavior.
# Prior to the code changes for issue #509, if invalid / malicious HTML input was
# observed, AntiSamy would simply attempt to sanitize (cleanse) it and it would
# only be logged. However, the code change made ESAPI comply with its
# documentation, which stated that a ValidationException should be thrown in
# such cases. Unfortunately, changing this behavior--especially when no one is
# 100% certain that the documentation was correct--could break existing code
# using ESAPI so after a lot of debate, issue #521 was created to restore the
# previous behavior, but still allow the documented behavior. (We did this
# because it wasn't really causing an security issues since AntiSamy would clean
# it up anyway and we value backward compatibility as long as it doesn't clearly
# present security vulnerabilities.)
# More defaults about this are written up under GitHub issue #521 and
# the pull request it references. Future major releases of ESAPI (e.g., ESAPI 3.x)
# will not support this previous behavior, but it will remain for ESAPI 2.x.
# Set this to 'throw' if you want the originally intended behavior of throwing
# that was fixed via issue #509. Set to 'clean' if you want want the HTML input
# sanitized instead.
#
# Possible values:
#   clean -- Use the legacy behavior where unsafe HTML input is logged and the
#            sanitized (i.e., clean) input as determined by AntiSamy and your
#            AntiSamy rules is returned. This is the default behavior if this
#            new property is not found.
#   throw -- The new, presumably correct and originally intended behavior where
#            a ValidationException is thrown when unsafe HTML input is
#            encountered.
