ContinueParsingCardRangesOnError:   Whether or not to continue parsing card ranges when a validation error is encountered.

When RequestCardRanges is called, the component will parse the card ranges returned in the PRes response packet. By default, if an error is encountered, the component will stop parsing, send an Erro packet to the Directory Server, and throw an exception. This setting can be used to instruct the component to continue parsing the card ranges, and adding the ranges that do not fail validation to the CardRanges collection prior to raising the error. The default value is False.

N Do not use decoupled authentication.

Note that if the element is not provided (default), the ACS would interpret this equivalent to a value of N.

DecoupledTimeRemaining:   Time remaining before a RReq should be received during a decoupled authentication.

When performing decoupled authentication, the 3DS Server will wait DecoupledMaxTimeout seconds for a Results Request (RReq) packet from the Directory Server indicating the results of the authentication. Generally, the ACS should send the RReq before the specified max time expires, even if authentication has not succeeded. If not successful, this would be indicated in the RReq. This config can be used to help track the time remaining before this RReq should be received, and is based on DecoupledMaxTimeout + 30 seconds.

See the AccountAgeIndicator configuration setting for the complete list of elements (all available as config settings) comprising Cardholder Account Information.

StoreCardRangeData:   Whether or not to store the card ranges in the CardRanges collection.

Indicates whether or not the component should store card ranges in the internal CardRanges collection after the RequestCardRanges method completes. When False, the card range data will only be available via the CardRange event. This can be useful in limiting memory usage of the component, especially when large amounts of ranges are returned.

The default value is True.

SuspiciousAccountActivity:   Suspicious account activity indicator.

Indicates whether the 3DS Requestor has experienced suspicious activity (including previous fraud) on the cardholder account.

Possible values are:

01 No suspicious activity has been observed
02 Suspicious activity has been observed

An element of the Cardholder Account Information provided by the 3DS Requestor in AReq messages, which is optional but strongly recommended to include. See the AccountAgeIndicator configuration setting for the complete list of elements (all available as config settings) comprising Cardholder Account Information.

ThreeRIIndicator:   3RI Indicator.

Indicates the type of 3RI request. This data element provides additional information to the ACS to determine the best approach for handing a 3RI request. Included in the Authorization Request Message (ARes) sent by the SendAuthRequest. Valid when DeviceChannel is set to "03," indicating 3RI.

Possible values are:

UseAESGCM:   Whether or not to use AESGCM as the encryption algorithm.

By default, the component will use JWS_ENC_ALG_ID_A128CBC_HS256AES when encrypting packets to send to the ACS. Setting this to true will instruct the component to use JWE_ENC_ALG_ID_A128GCM instead.

UseJsonDOM:   Whether or not the component should build an internal DOM when parsing card ranges.

When the RequestCardRanges method is called, by default the component will construct an internal DOM (Document Object Model) when parsing the returned data. When set to False, this will instruct the component not to build this model, which can be useful in limiting memory usage of the component, especially when large amounts of ranges are returned.

The default value is True. Note that when False, the XPath settings will not be available.

WhitelistStatus:   Whitelist Status.

Enables the communication of trusted beneficiary/whitelist status between the ACS, the DS and the 3DS Requestor.

Y 3DS Requestor is whitelisted by cardholder

XChildCount:   The number of child elements of the current element.

The number of child attributes of the current element. The XChild configuration settings will be indexed from 0 to (XChildCount - 1).

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XChildName[i]:   The name of the child element.

Provides the name of the i'th child element of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XChildXText[i]:   The inner text of the child element.

Provides the inner text of the i'th child element of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XElement:   The name of the current element.

Provides the name of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XParent:   The parent of the current element.

Provides the parent of the current element.

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XPath:   Provides a way to point to a specific element in the returned XML or JSON response.

The XPath setting allows you to point to specific elements in the XML or JSON response.

When XPath is set to a valid path, XElement points to the name of the element, with XText, XParent, XSubTree, XChildCount, XChildName[i], and XChildXText[i] providing other properties of the element.

XPath Syntax

XPath syntax is available for both XML and JSON documents. An XPath is a series of one or more element accessors separated by the / character, for example: /A/B/C/D. An XPath can be absolute (i.e., it starts with /), or it can be relative to the current XPath location.

The following are possible values for an element accessor, which operates relative to the current location specified by the XPath accessors which proceed it in the overall XPath string:

Accessor Description
name The first element with a particular name. Can be *.
[i] The i-th element.
name[i] The i-th element with a particular name.
[last()] The last element.
[last()-i] The element i before the last element.
name[@attrname="attrvalue"]The first element with a particular name that contains the specified attribute-value pair.
Supports single and double quotes. (XML Only)
. The current element.
.. The parent element.

Note: XPath indices are 1-based.

XPath Examples

Assuming the following XML response:

<firstlevel>
  <one>value</one>
  <two>
    <item>first</item>
    <item>second</item>
  </two>
  <three>value three</three>
</firstlevel>

Or, alternatively, the following JSON response:

{
  "firstlevel": {
    "one": "value",
    "two": ["first", "second"],
    "three": "value three"
  }
}

Here are some examples of valid XPaths:

DescriptionXML XPath JSON XPath
Document root / /json
Specific element /firstlevel/one /json/firstlevel/one
i-th child /firstlevel/two/item[2]/json/firstlevel/two/[2]

This is not an exhaustive list by any means, but should provide a general idea of the possibilities.

XSubTree:   A snapshot of the current element in the document.

Provides the entirety of the current element (including its sub-elements).

The current element is specified via the XPath configuration setting. This configuration setting is read-only.

XText:   The text of the current element.

Provides the inner text of the current element.

The current element is specified in the XPath configuration setting. This configuration setting is read-only.

SSL Configuration Settings

CACertFilePaths:   The paths to CA certificate files when using Mono on Unix/Linux.

This setting specifies the paths on disk to CA certificate files when using Mono on Unix/Linux. It is not applicable in any other circumstances.

The value is formatted as a list of paths separated by semicolons. The component will check for the existence of each file in the order specified. When a file is found the CA certificates within the file will be loaded and used to determine the validity of server certificates.

The default value is:

/etc/ssl/ca-bundle.pem;/etc/pki/tls/certs/ca-bundle.crt;/etc/ssl/certs/ca-certificates.crt;/etc/pki/tls/cacert.pem

LogSSLPackets:   Controls whether SSL packets are logged when using the internal security API.

When the UseInternalSecurityAPI configuration setting is True, this setting controls whether SSL packets should be logged. By default, this setting is False, as it is only useful for debugging purposes.

When enabled, SSL packet logs are output using the SSLStatus event, which will fire each time an SSL packet is sent or received.

Enabling this setting has no effect if UseInternalSecurityAPI is False.

ReuseSSLSession:   Determines if the SSL session is reused.

If set to true, the component will reuse the context if and only if the following criteria are met:

  • The target host name is the same.
  • The system cache entry has not expired (default timeout is 10 hours).
  • The application process that calls the function is the same.
  • The logon session is the same.
  • The instance of the component is the same.

SSLCACerts:   A newline separated list of CA certificate to use during SSL client authentication.

This setting specifies one or more CA certificates to be included in the request when performing SSL client authentication. Some servers require the entire chain, including CA certificates, to be presented when performing SSL client authentication. The value of this setting is a newline (CrLf) separated list of certificates. For instance:


-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw
...
eWHV5OW1K53o/atv59sOiW5K3crjFhsBOd5Q+cJJnU+SWinPKtANXMht+EDvYY2w

-----END CERTIFICATE-----

SSLCheckCRL:   Whether to check the Certificate Revocation List for the server certificate.

This setting specifies whether the component will check the Certificate Revocation List specified by the server certificate. If set to true the component will first obtain the list of CRL URLs from the server certificate's CRL distribution points extension. The component will then make HTTP requests to each CRL endpoint to check the validity of the server's certificate. If the certificate has been revoked or any other issues are found during validation the component throws an exception.

When set to false (default) the CRL check will not be performed by the component.

SSLCipherStrength:   The minimum cipher strength used for bulk encryption.

This minimum cipher strength largely dependent on the security modules installed on the system. If the cipher strength specified is not supported, an error will be returned when connections are initiated.

Please note that this setting contains the minimum cipher strength requested from the security library. The actual cipher strength used for the connection is shown by the SSLStatus event.

Use this setting with caution. Requesting a lower cipher strength than necessary could potentially cause serious security vulnerabilities in your application.

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList config setting.

SSLEnabledCipherSuites:   The cipher suite to be used in an SSL negotiation.

The enabled cipher suites to be used in SSL negotiation.

By default, the enabled cipher suites will include all available ciphers ("*").

The special value "*" means that the component will pick all of the supported cipher suites. If SSLEnabledCipherSuites is set to any other value, only the specified cipher suites will be considered.

Multiple cipher suites are separated by semicolons.

Example values when UseInternalSecurityAPI is False (default):

obj.config("SSLEnabledCipherSuites=*");
obj.config("SSLEnabledCipherSuites=CALG_AES_256");
obj.config("SSLEnabledCipherSuites=CALG_AES_256;CALG_3DES");

When TLS 1.3 is negotiated (see SSLEnabledProtocols) only the following cipher suites are supported:

  • TLS_AES_256_GCM_SHA384
  • TLS_CHACHA20_POLY1305_SHA256
  • TLS_AES_128_GCM_SHA256

SSLEnabledCipherSuites is used together with SSLCipherStrength.

SSLEnabledProtocols:   Used to enable/disable the supported security protocols.

Used to enable/disable the supported security protocols.

Not all supported protocols are enabled by default (the value of this setting is 4032). If you want more granular control over the enabled protocols, you can set this property to the binary 'OR' of one or more of the following values:

TLS1.312288 (Hex 3000)
TLS1.23072 (Hex C00) (Default)
TLS1.1768 (Hex 300) (Default)
TLS1 192 (Hex C0) (Default)
SSL3 48 (Hex 30)
SSL2 12 (Hex 0C)

When the provider is OpenSSL, SSLCipherStrength is currently not supported. This functionality is instead made available through the OpenSSLCipherList setting.

Note: TLS 1.1 and TLS1.2 support are only available starting with Windows 7.

Note: Enabling TLS 1.3 will automatically set UseInternalSecurityAPI to True.

SSLEnableRenegotiation:   Whether the renegotiation_info SSL extension is supported.

This setting specifies whether the renegotiation_info SSL extension will be used in the request when using the internal security API. This setting is true by default, but can be set to false to disable the extension.

This setting is only applicable when UseInternalSecurityAPI is set to true.

SSLIncludeCertChain:   Whether the entire certificate chain is included in the SSLServerAuthentication event.

This setting specifies whether the Encoded parameter of the SSLServerAuthentication event contains the full certificate chain. By default this value is False and only the leaf certificate will be present in the Encoded parameter of the SSLServerAuthentication event.

If set to True all certificates returned by the server will be present in the Encoded parameter of the SSLServerAuthentication event. This includes the leaf certificate, any intermediate certificate, and the root certificate.

Note: When UseInternalSecurityAPI is set to True this value is automatically set to True. This is needed for proper validation when using the internal provider.

SSLProvider:   The name of the security provider to use.

Change this setting to use security providers other than the system default.

Use this setting with caution. Disabling SSL security or pointing to the wrong provider could potentially cause serious security vulnerabilities in your application.

The special value "*" (default) picks the default SSL provider defined in the system.

The special value "Internal" picks the internal SSL implementation. This does not rely on any system libraries. This is equivalent to setting UseInternalSecurityAPI to True.

Note: On Windows systems, the default SSL Provider is "Microsoft Unified Security Protocol Provider" and cannot be changed except to a value of "Internal".

SSLSecurityFlags:   Flags that control certificate verification.

The following flags are defined (specified in hexadecimal notation). They can be or-ed together to exclude multiple conditions:

0x00000001Ignore time validity status of certificate.
0x00000002Ignore time validity status of CTL.
0x00000004Ignore non-nested certificate times.
0x00000010Allow unknown Certificate Authority.
0x00000020Ignore wrong certificate usage.
0x00000100Ignore unknown certificate revocation status.
0x00000200Ignore unknown CTL signer revocation status.
0x00000400Ignore unknown Certificate Authority revocation status.
0x00000800Ignore unknown Root revocation status.
0x00008000Allow test Root certificate.
0x00004000Trust test Root certificate.
0x80000000Ignore non-matching CN (certificate CN not-matching server name).

This functionality is currently not available in Java or when the provider is OpenSSL.

SSLServerCACerts:   A newline separated list of CA certificate to use during SSL server certificate validation.

This setting optionally specifies one or more CA certificates to be used when verifying the server certificate. When verifying the server's certificate the certificates trusted by the system will be used as part of the verification process. If the server's CA certificates are not installed to the trusted system store, they may be specified here so they are included when performing the verification process. This setting should only be set if the server's CA certificates are not already trusted on the system and cannot be installed to the trusted system store.

The value of this setting is a newline (CrLf) separated list of certificates. For instance:


-----BEGIN CERTIFICATE-----
MIIEKzCCAxOgAwIBAgIRANTET4LIkxdH6P+CFIiHvTowDQYJKoZIhvcNAQELBQAw

-----END CERTIFICATE-----

TLS12SignatureAlgorithms:   Defines the allowed TLS 1.2 signature algorithms when UseInternalSecurityAPI is True.

This setting specifies the allowed server certificate signature algorithms when UseInternalSecurityAPI is True and SSLEnabledProtocols is set to allow TLS 1.2.

When specified the component will verify that the server certificate signature algorithm is among the values specified in this setting. If the server certificate signature algorithm is unsupported the component throws an exception.

The format of this value is a comma separated list of hash-signature combinations. For instance:

IPPort.Config("UseInternalSecurityAPI=true");
IPPort.Config("SSLEnabledProtocols=3072"); //TLS 1.2
IPPort.Config("TLS12SignatureAlgorithms=sha256-rsa,sha256-dsa,sha1-rsa,sha1-dsa");
The default value for this setting is sha512-ecdsa,sha512-rsa,sha512-dsa,sha384-ecdsa,sha384-rsa,sha384-dsa,sha256-ecdsa,sha256-rsa,sha256-dsa,sha224-ecdsa,sha224-rsa,sha224-dsa,sha1-ecdsa,sha1-rsa,sha1-dsa.

In order to not restrict the server's certificate signature algorithm, specify an empty string as the value for this setting, which will cause the signature_algorithms TLS 1.2 extension to not be sent.

TLS12SupportedGroups:   The supported groups for ECC.

This setting specifies a comma separated list of named groups used in TLS 1.2 for ECC.

The default value is ecdhe_secp256r1,ecdhe_secp384r1,ecdhe_secp521r1.

When using TLS 1.2 and UseInternalSecurityAPI is set to True, the values refer to the supported groups for ECC. The following values are supported:

  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1" (default)

TLS13KeyShareGroups:   The groups for which to pregenerate key shares.

This setting specifies a comma separated list of named groups used in TLS 1.3 for key exchange. The groups specified here will have key share data pregenerated locally before establishing a connection. This can prevent an additional round trip during the handshake if the group is supported by the server.

The default value is set to balance common supported groups and the computational resources required to generate key shares. As a result only some groups are included by default in this setting.

Note: All supported groups can always be used during the handshake even if not listed here, but if a group is used which is not present in this list it will incur an additional round trip and time to generate the key share for that group.

In most cases this setting does not need to be modified. This should only be modified if there is a specific reason to do so.

The default value is ecdhe_x25519,ecdhe_secp256r1,ecdhe_secp384r1,ffdhe_2048,ffdhe_3072

The values are ordered from most preferred to least preferred. The following values are supported:

  • "ecdhe_x25519" (default)
  • "ecdhe_x448"
  • "ecdhe_secp256r1" (default)
  • "ecdhe_secp384r1" (default)
  • "ecdhe_secp521r1"
  • "ffdhe_2048" (default)
  • "ffdhe_3072" (default)
  • "ffdhe_4096"
  • "ffdhe_6144"
  • "ffdhe_8192"

TLS13SignatureAlgorithms:   The allowed certificate signature algorithms.

This setting holds a comma separated list of allowed signature algorithms. Possible values are:

  • "ed25519" (default)
  • "ed448" (default)
  • "ecdsa_secp256r1_sha256" (default)
  • "ecdsa_secp384r1_sha384" (default)
  • "ecdsa_secp521r1_sha512" (default)
  • "rsa_pkcs1_sha256" (default)
  • "rsa_pkcs1_sha384" (default)
