XMLSig Class

Properties   Methods   Events   Config Settings   Errors  

The XMLSig class is used to sign XML and verify signed XML.

Syntax

class ipworksencrypt.XMLSig

Remarks

The XMLSig component provides an easy to use API for signing and verifying signed XML. The sign method will create signed XML with an enveloped signature. The verify_signature method will attempt to verify the signature(s) within a XML document.

Sign

Before calling sign specify the XML to sign by setting input_file, or input_xml.

The Reference* properties must be set. At least one reference must be set. A reference defines the XML element to sign, and the options that specify how it is transformed and hashed during the signing process.

Set certificate to a certificate with private key.

Optionally set the canonicalization_method. This determines how the signature itself is canonicalized. signing_algorithm defines the algorithm used to sign. The signature_xpath property may be set to specify the location in the XML document where the signature will be placed.

Lastly, call sign to sign the XML.

The following properties are applicable when calling this method:

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

Verify a Signature

When verify_signature is called, the class will scan the XML document and fire the on_signature_info event for each signature that is found. When the on_signature_info event fires the Reference* properties will be populated.

Within the on_signature_info event the reference_xml_element property must be set to the location of the XML element to which the signature applies. The reference_uri property may contain data helpful to locating the XML element.

The reference_xml_element property specifies the XPath to the element. For instance:

/root/myElement XPath syntax
/root/[1] XPath syntax using an index
/root/ns:myElement XPath syntax where the element has a namespace
myElement Just the element name
@id=myid Attribute selector: This will select an element with an attribute "id" whose value is "myid".
/root/myElement[1]/ns:name2[@attr=attrValue] XPath syntax using an index and attribute selector

The signature is verified either using a key parsed from the signed XML, or using the certificate specified by the SignerCert* properties. The class will automatically parse the signer certificate (if present) from the signed XML and populate the SignerCert* properties with the parsed value.

When on_signature_info fires, if the SignerCertParsed parameter is True the SignerCert* properties may be inspected to see the details of the parsed certificate. If SignerCertParsed is False, then the SignerCert* properties must be set to a valid certificate for signature verification to proceed.

When the on_signature_info event finishes firing, the certificate present in the SignerCert* properties will be used to verify the signature, whether this is the certificate automatically parsed by the class or a different certificate specified within the event.

If the signature was successfully verified the method will return without error. If the signature was not verified the method fails with an error.

Code Example: SSH Authentication with Security Key certmgr.CertStoreType = CertStoreTypes.cstSecurityKey; certmgr.OnCertList += (s, e) => { secKeyBlob = e.CertEncoded; }; certmgr.CertStore = @"C:\Program Files\OpenSC Project\OpenSC\pkcs11\opensc-pkcs11.dll"; certmgr.CertStorePassword = "123456"; //PIN certmgr.ListStoreCertificates(); sftp.SSHCert = new Certificate(CertStoreTypes.cstSecurityKey, secKeyBlob, "123456", "*"); sftp.SSHUser = "test"; sftp.SSHLogon("myhost", 22);

21 (cstBCFKSFile)The certificate store is the name of a file that contains a BCFKS (Bouncy Castle FIPS Key Store). Note: this store type is only available in Java and .NET.
22 (cstBCFKSBlob)The certificate store is a string (binary or base64-encoded) representing a certificate store in BCFKS (Bouncy Castle FIPS Key Store) format. Note: this store type is only available in Java and .NET.
99 (cstAuto)The store type is automatically detected from the input data. This setting may be used with both public and private keys and can detect any of the supported formats automatically.

signer_cert_subject Property

This is the subject of the certificate used for client authentication.

Syntax

def get_signer_cert_subject() -> str: ...
def set_signer_cert_subject(value: str) -> None: ...

signer_cert_subject = property(get_signer_cert_subject, set_signer_cert_subject)

Default Value

""

Remarks

This is the subject of the certificate used for client authentication.

This property must be set after all other certificate properites are set. When this property is set, a search is performed in the current certificate store certificate with matching subject.

If a matching certificate is found, the property is set to the full subject of the matching certificate.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks a random certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, E=support@nsoftware.com". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.
OOrganization
OUOrganizational Unit
LLocality
SState
CCountry
EEmail Address

If a field value contains a comma it must be quoted.

signing_algorithm Property

The signing algorithm.

Syntax

def get_signing_algorithm() -> str: ...
def set_signing_algorithm(value: str) -> None: ...

signing_algorithm = property(get_signing_algorithm, set_signing_algorithm)

Default Value

""

Remarks

This property specifies the signing algorithm.

This may be set before calling sign. This value will be set after calling verify_signature. Possible values are:

  • "RSA-SHA1" (default)
  • "RSA-SHA256"
  • "DSA-SHA1"
  • "HMAC-SHA1"
Note: When set to "HMAC-SHA1" hmac_key must also be set.

config Method

Sets or retrieves a configuration setting.

Syntax

def config(configuration_string: str) -> str: ...

Remarks

config is a generic method available in every class. It is used to set and retrieve configuration settings for the class.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

do_events Method

Processes events from the internal message queue.

Syntax

def do_events() -> None: ...

Remarks

When do_events is called, the class processes any available events. If no events are available, it waits for a preset period of time, and then returns.

reset Method

Resets the class.

Syntax

def reset() -> None: ...

Remarks

When called, the component will reset all of its properties to their default values.

sign Method

Signs the XML.

Syntax

def sign() -> None: ...

Remarks

This methods signs the XML.

Before calling sign specify the XML to sign by setting input_file, or input_xml.

The Reference* properties must be set. At least one reference must be set. A reference defines the XML element to sign, and the options that specify how it is transformed and hashed during the signing process.

Set certificate to a certificate with private key.

Optionally set the canonicalization_method. This determines how the signature itself is canonicalized. signing_algorithm defines the algorithm used to sign. The signature_xpath property may be set to specify the location in the XML document where the signature will be placed.

Lastly, call sign to sign the XML.

The following properties are applicable when calling this method:

Input and Output Properties

The class will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

verify_signature Method

Verifies signed XML.

Syntax

def verify_signature() -> None: ...

Remarks

This method verifies signatures contained in the XML.

When verify_signature is called, the class will scan the XML document and fire the on_signature_info event for each signature that is found. When the on_signature_info event fires the Reference* properties will be populated.

Within the on_signature_info event the reference_xml_element property must be set to the location of the XML element to which the signature applies. The reference_uri property may contain data helpful to locating the XML element.

The reference_xml_element property specifies the XPath to the element. For instance:

/root/myElement XPath syntax
/root/[1] XPath syntax using an index
/root/ns:myElement XPath syntax where the element has a namespace
myElement Just the element name
@id=myid Attribute selector: This will select an element with an attribute "id" whose value is "myid".
/root/myElement[1]/ns:name2[@attr=attrValue] XPath syntax using an index and attribute selector

The signature is verified either using a key parsed from the signed XML, or using the certificate specified by the SignerCert* properties. The class will automatically parse the signer certificate (if present) from the signed XML and populate the SignerCert* properties with the parsed value.

When on_signature_info fires, if the SignerCertParsed parameter is True the SignerCert* properties may be inspected to see the details of the parsed certificate. If SignerCertParsed is False, then the SignerCert* properties must be set to a valid certificate for signature verification to proceed.

When the on_signature_info event finishes firing, the certificate present in the SignerCert* properties will be used to verify the signature, whether this is the certificate automatically parsed by the class or a different certificate specified within the event.

If the signature was successfully verified the method will return without error. If the signature was not verified the method fails with an error.

on_error Event

Information about errors during data delivery.

Syntax

class XMLSigErrorEventParams(object):
  @property
  def error_code() -> int: ...

  @property
  def description() -> str: ...

# In class XMLSig:
@property
def on_error() -> Callable[[XMLSigErrorEventParams], None]: ...
@on_error.setter
def on_error(event_hook: Callable[[XMLSigErrorEventParams], None]) -> None: ...

Remarks

The on_error event is fired in case of exceptional conditions during message processing. Normally the class fails with an error.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

on_progress Event

Fired as progress is made.

Syntax

class XMLSigProgressEventParams(object):
  @property
  def bytes_processed() -> int: ...

  @property
  def percent_processed() -> int: ...

  @property
  def operation() -> int: ...

  @property
  def is_eof() -> bool: ...
  @is_eof.setter
  def is_eof(value) -> None: ...

# In class XMLSig:
@property
def on_progress() -> Callable[[XMLSigProgressEventParams], None]: ...
@on_progress.setter
def on_progress(event_hook: Callable[[XMLSigProgressEventParams], None]) -> None: ...

Remarks

This event is fired automatically as data is processed by the class.

The PercentProcessed parameter indicates the current status of the operation.

The BytesProcessed parameter holds the total number of bytes processed so far.

The Operation parameter is only applicable when either ReadFromProgressEvent or WriteToProgressEvent is set to True. This parameter defines whether a Read or Write operation is required. If the configuration settings are not set this parameter will always return 0. Possible values are:

0None
1Read
2Write

The IsEOF parameter is only applicable when either ReadFromProgressEvent or WriteToProgressEvent is set to True. This parameter defines whether the Read or Write operation is complete. When the Operation is Read (1) this parameter must be set to indicate that all data has been supplied to the class. When the Operation is Write (2) this value may be queried to determine when all data has been processed.

on_signature_info Event

Fired when a signature is found.

Syntax

class XMLSigSignatureInfoEventParams(object):
  @property
  def signature_id() -> str: ...

  @property
  def signer_cert_parsed() -> bool: ...

# In class XMLSig:
@property
def on_signature_info() -> Callable[[XMLSigSignatureInfoEventParams], None]: ...
@on_signature_info.setter
def on_signature_info(event_hook: Callable[[XMLSigSignatureInfoEventParams], None]) -> None: ...

Remarks

This event fires when calling verify_signature for each signature found within the XML document.

SignatureId is the id of the signature.

SignerCertParsed indicates whether the signer's certificate was automatically parsed from the signed XML.

Verification Notes

When verify_signature is called, the class will scan the XML document and fire the on_signature_info event for each signature that is found. When the on_signature_info event fires the Reference* properties will be populated.

Within the on_signature_info event the reference_xml_element property must be set to the location of the XML element to which the signature applies. The reference_uri property may contain data helpful to locating the XML element.

The reference_xml_element property specifies the XPath to the element. For instance:

/root/myElement XPath syntax
/root/[1] XPath syntax using an index
/root/ns:myElement XPath syntax where the element has a namespace
myElement Just the element name
@id=myid Attribute selector: This will select an element with an attribute "id" whose value is "myid".
/root/myElement[1]/ns:name2[@attr=attrValue] XPath syntax using an index and attribute selector

The signature is verified either using a key parsed from the signed XML, or using the certificate specified by the SignerCert* properties. The class will automatically parse the signer certificate (if present) from the signed XML and populate the SignerCert* properties with the parsed value.

When on_signature_info fires, if the SignerCertParsed parameter is True the SignerCert* properties may be inspected to see the details of the parsed certificate. If SignerCertParsed is False, then the SignerCert* properties must be set to a valid certificate for signature verification to proceed.

When the on_signature_info event finishes firing, the certificate present in the SignerCert* properties will be used to verify the signature, whether this is the certificate automatically parsed by the class or a different certificate specified within the event.

If the signature was successfully verified the method will return without error. If the signature was not verified the method fails with an error.

on_status Event

Provides information about the current operation.

Syntax

class XMLSigStatusEventParams(object):
  @property
  def message() -> str: ...

# In class XMLSig:
@property
def on_status() -> Callable[[XMLSigStatusEventParams], None]: ...
@on_status.setter
def on_status(event_hook: Callable[[XMLSigStatusEventParams], None]) -> None: ...

Remarks

The event is fired for informational and logging purposes only. It may be used to track the progress of an operation.

The level of detail is controlled by the LogLevel setting.

XMLSig Config Settings

The class accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.

XMLSig Config Settings

KeyName:   The name of the key used to sign the XML.

This setting optionally holds the key name which may be useful to the recipient to help identify the key used to create the signature. This may be set before calling sign. When calling verify_signature this may be queried inside the on_signature_info event.

Note that this value is only informative, it does not affect processing.

LogLevel:   Specifies the level of detail that is logged.

This setting controls the level of detail that is logged through the on_status event. Possible values are:

0 (None)No events are logged.
1 (Info - default)Informational events are logged.
2 (Verbose)Detailed data is logged.
3 (Debug)Debug data is logged.

NormalizeLineEndings:   Whether to normalize line endings when calculating the reference digest.

This setting specifies whether to normalize line endings when calculating the reference digest. When set to True all line endings will be converted to LF. The default value is True.

PreserveWhitespace:   Whether to preserve whitespace in the signature.

This setting specifies whether whitespace is preserved when canonicalizing XML. The default value is False.

ReadFromProgressEvent:   Whether to read input data from inside the progress event.

When set to True this setting allows input data to be specified from within the on_progress event. The class will repeatedly fire the on_progress event to ask for data. Inside the event set input_xml when the Operation parameter of the event is 1 (Read). When all data has been provided set the IsEOF parameter of the event to True. This allows input data to be chunked and provided piece by piece. The default value is False.

SignatureRelationship:   Whether the signature is a child or sibling of the SignatureXPath.

This setting specifies whether the created signature is included as a child or sibling of the element specified by signature_xpath. If this is set to 0 (default), the signature is inserted as a child of the element. If this is set to 1, the signature is inserted as a sibling after the element. The default value is 0 (child).

Example: SignatureRelationship is set to 0 (child - default) xmlsig1.SignatureXPath = "/root/node1"; Produces XML like:

<root>
  <node1>
    <ds:Signature>...</ds:Signature>
  </node1>
  <node2></node2>
  <node3></node3>
</root>

Example: SignatureRelationship is set to 1 (sibling) xmlsig1.SignatureXPath = "/root/node1"; xmlsig1.Config("SignatureRelationship=1"); Produces XML like:

<root>
  <node1></node1>
  <ds:Signature>...</ds:Signature>
  <node2></node2>
  <node3></node3>
</root>

SignerCertCount:   The number of parsed signer certificates when verifying a signature.

This setting is populated when calling verify_signature. It holds the number of signer certificates that were parsed from the message. In most cases a single certificate is present and signer_cert is populated. In some cases, multiple certificates in a chain may be present, in that case each parsed certificate can be accessed via this property and SignerCertEncoded. For instance: int certCount = Int32.Parse(xmlsig.Config("SignerCertCount")); for(int i=0;i<certCount;i++) { Console.WriteLine(xmlsig.Config("SignerCertEncoded[ " + i + "]")); }

SignerCertEncoded[i]:   The parsed signer certificate.

This setting is used in conjunction with SignerCertCount to retrieve the base64 encoded signer certificate parsed from the message. Valid values for the index are from 0 to SignerCertCount - 1. SignerCertEncoded

SignWithCryptoAPI:   Whether to use the Crypto API for signing operations.

This setting determines whether to use the Microsoft Crypto API to sign. This is helpful in cases where the certificate is present in the Windows Certificate Store but the private key is not marked as exportable. For instance when using a USB security key. The default value is False.

Note: This functionality is only available on Windows.

WriteToProgressEvent:   Whether to write output data so it is accessible from inside the progress event.

When set to True this setting allows output data to be obtained from within the on_progress event. The class will repeatedly fire the on_progress event to provide output data. Inside the event check output_xml when the Operation parameter of the event is 2 (Write). The IsEOF parameter should be checked inside the event to determine when all output data has been provided. This allows output data to be chunked and obtained piece by piece. The default value is False.

Base Config Settings

BuildInfo:   Information about the product's build.

When queried, this setting will return a string containing information about the product's build.

CodePage:   The system code page used for Unicode to Multibyte translations.

The default code page is Unicode UTF-8 (65001).

LicenseInfo:   Information about the current license.

When queried, this setting will return a string containing information about the license this instance of a class is using. It will return the following information:

  • Product: The product the license is for.
  • Product Key: The key the license was generated from.
  • License Source: Where the license was found (e.g., RuntimeLicense, License File).
  • License Type: The type of license installed (e.g., Royalty Free, Single Server).
  • Last Valid Build: The last valid build number for which the license will work.
ProcessIdleEvents:   Whether the class uses its internal event loop to process events when the main thread is idle.

If set to False, the class will not fire internal idle events. Set this to False to use the class in a background thread on Mac OS. By default, this setting is True.

SelectWaitMillis:   The length of time in milliseconds the class will wait when DoEvents is called if there are no events to process.

If there are no events to process when do_events is called, the class will wait for the amount of time specified here before returning. The default value is 20.

UseInternalSecurityAPI:   Tells the class whether or not to use the system security libraries or an internal implementation.

By default the class will use the system security libraries to perform cryptographic functions where applicable. Setting this to True tells the class to use the internal implementation instead of using the system's security API.
