# # 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. # # ExperimentalAccessController requires ESAPI-AccessControlPolicy.xml in .esapi directory ESAPI.AccessControl=org.owasp.esapi.reference.DefaultAccessController # FileBasedAuthenticator requires users.txt file in .esapi directory ESAPI.Authenticator=org.owasp.esapi.reference.FileBasedAuthenticator ESAPI.Encoder=org.owasp.esapi.reference.DefaultEncoder ESAPI.Encryptor=org.owasp.esapi.reference.crypto.JavaEncryptor ESAPI.Executor=org.owasp.esapi.reference.DefaultExecutor ESAPI.HTTPUtilities=org.owasp.esapi.reference.DefaultHTTPUtilities ESAPI.IntrusionDetector=org.owasp.esapi.reference.DefaultIntrusionDetector # Log4JFactory Requires log4j.xml or log4j.properties in classpath - http://www.laliluna.de/log4j-tutorial.html ESAPI.Logger=org.owasp.esapi.reference.Log4JLogFactory #ESAPI.Logger=org.owasp.esapi.reference.JavaLogFactory ESAPI.Randomizer=org.owasp.esapi.reference.DefaultRandomizer ESAPI.Validator=org.owasp.esapi.reference.DefaultValidator #=========================================================================== # ESAPI Authenticator # Authenticator.AllowedLoginAttempts=3 Authenticator.MaxOldPasswordHashes=13 Authenticator.UsernameParameterName=username Authenticator.PasswordParameterName=password # RememberTokenDuration (in days) Authenticator.RememberTokenDuration=14 # Session Timeouts (in minutes) Authenticator.IdleTimeoutDuration=20 Authenticator.AbsoluteTimeoutDuration=120 #=========================================================================== # ESAPI Encoder # # ESAPI canonicalizes input before validation to prevent bypassing filters with encoded attacks. # Failure to canonicalize input is a very common mistake when implementing validation schemes. # Canonicalization is automatic when using the ESAPI Validator, but you can also use the # following code to canonicalize data. # # ESAPI.Encoder().canonicalize( "%22hello world"" ); # # Multiple encoding is when a single encoding format is applied multiple times.

Allowing multiple encoding is strongly discouraged. Encoder.AllowMixedEncoding=false # The default list of codecs to apply when canonicalizing untrusted data. The list should include the codecs # for all downstream interpreters or decoders. For example, if the data is likely to end up in a URL, HTML, or # inside JavaScript, then the list of codecs below is appropriate. The order of the list is not terribly important. Encoder.DefaultCodecList=HTMLEntityCodec,PercentCodec,JavaScriptCodec #=========================================================================== # 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.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'. # 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. Encryptor.CipherText.useMAC=true # Whether or not the PlainText object may be overwritten and then marked # eligible for garbage collection. If not set, this is still treated as 'true'. Encryptor.PlainText.overwrite=true # Do not use DES except in a legacy situations. 56-bit is way too small key size. #Encryptor.EncryptionKeyLength=56 #Encryptor.EncryptionAlgorithm=DES # TripleDES is considered strong enough for most purposes. # Note: There is also a 112-bit version of DESede.
