 # 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?

 # WARNING: Operating system protection should be used to lock down the .esapi
 # resources directory and all the files inside and all the directories all the
 # 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.
 #
 #		YOU HAVE BEEN WARNED!!! More details are in the ESAPI 2.0 Release Notes.

 #===========================================================================
 # ESAPI Configuration
 #
 # 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.printProperties=true
 # 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.
 #
 # 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=tzfztf56ftv
 Encryptor.MasterSalt=123456ztrewq
 # 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.CipherTransformation=AES/CBC/PKCS5Padding

 # 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.

 # Additional cipher modes allowed for ESAPI 2.0 encryption. These

 # 'Encryptor.cipher_modes.combined_modes'.
 # Note: We will add support for streaming modes like CFB & OFB once
 # we add support for 'specified' to the property 'Encryptor.ChooseIVMethod'
 # (probably in ESAPI 2.1).
 # DISCUSS: Better name?
 Encryptor.cipher_modes.additional_allowed=CBC
 # 128-bit is almost always sufficient and appears to be more resistant to
 # 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
 # cipher transformation, otherwise this will be ignored after logging a
 # warning.
 #
 # NOTE: This is what applies BOTH ESAPI 1.4 and 2.0. See warning above about mixing!
 Encryptor.EncryptionKeyLength=128
 # 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".
 # (Note that the block size for AES is 16 bytes == 128 bits.)
 #
 Encryptor.fixedIV=0x000102030405060708090a0b0c0d0e0f
 # 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.
