The PDFSigner class signs PDF documents digitally.

Syntax

class secureblackbox.PDFSigner

Remarks

PDFSigner can sign PDF documents in accordance with a selection of PDF and PAdES signature standards.

Standards and technologies supported

PDFSigner can create PDF signatures that match the following baseline standards:

Generic PDF signatures (ISO 32000)
PAdES: all profiles are supported (BES, EPES, T, LTV, B-B, B-T, and others) (ETSI EN 319 142-1 and others)
Signature and document timestamps using external TSAs.
All industry-standard cryptographic algorithms (RSA, ECDSA, SHA256-512, and many others).

Configuring the signature spec

Configuring PDFSigner to produce signatures of the right type is one of the most important questions you need to address. Normally the service or software you will be communicating your PDF documents to will provide you with the list of requirements that your signatures should match.

Typically, those will dictate the following key aspects of the signatures:

Level (BES, T, or LTV). This can be adjusted with the property (Note: when creating EPES signatures you need to provide the signature and properties).
Timestamp requirement: provide the address of your online TSA service via the timestamp_server property.
When creating LTV signatures, tune up validation parameters via the revocation_check, offline_mode, and ignore_chain_validation_errors properties.
To create a document timestamp, sign your document first, and then sign the result again with set to pslDocumentTimestamp and timestamp_server pointing to the TSA URL.

Signing certificates

PDFSigner can use certificates residing on different media. Besides generic certificates stored in PFX or PEM files (A1), it can operate with non-exportable certificates residing on hardware media (A3) or in the cloud.

Non-exportable certificates can be accessed transparently via a Windows CSP or a PKCS#11 driver, if supplied by the certificate issuer. Proprietary interfaces can be plugged in with the external signing feature (see below).

You can use the CertificateManager and CertificateStorage classes to load the signing certificate. Assign the certificate to the signing_certificate property, and optionally provide the remainder of its chain via the signing_chain property.

Note: If signing with a non-exportable key (such as residing on a hardware device or in the cloud), please make sure you keep the original CertificateStorage object open until the signing is completed. This is because the storage class provides a 'bridge' to the private key. If the storage is closed prematurely, this bridge is destroyed, and the private key can't be used.

You don't need to provide a signing certificate or chain when creating document timestamp signatures, since this type of signature is done with a TSA's certificate.

Widget adjustment

PDFSigner provides means to customize the look of the signature widget to be shown on the document page. Create your very own signatures in the form of your company's logo, a handwritten signature, or a wet seal.

Alternatively, you can choose not to associate any widget with your signature by setting to true.

Please check out this self-describing PDF document for good guidance on widget positioning, background styles, and text formatting.

Signing the document

Now that you have set up all signature, certificate, and widget properties, it is time to sign. You can provide the input document in one of the following forms: as a file (assign the path to the input_file property), as a stream (assign to the input_stream property), or as a byte array (assign to input_bytes). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via output_file and output_stream respectively, or by reading the resulting document bytes from the output_bytes property after the signing.

Having set up the input and output, call the class's sign method. This will initiate the signing process. Depending on the settings, the signing may be as straightforward as calculating the document hash and signing it with the private key (e.g. in the PAdES-BES signing variant), or it may involve advanced chain validation routines (PAdES-LTV). During the latter, the class may contact a number of external revocation information sources (CRL and OCSP servers) to establish the validity of the signing certificate.

If a TSA server was provided via the timestamp_server property, the class will contact it too to timestamp the new signature.

During the signing, PDFSigner may fire events to let your code know of certain conditions. If the input document is encrypted but no decryption parameters were found in the password and decryption_certificate properties, the class will fire the on_encrypted event to tell your code that it needs decryption information to be able to continue with the signing. It may fire on_tls_cert_validate if one of the HTTP endpoints involved during the operation (which may be a CRL, OCSP, or TSA service) works over TLS and needs its certificate to be validated.

External signing and DCAuth

PDFSigner, like many other classes offered by the product, supports two methods of signing with external keys. These methods are fully independent of each other: you can choose the one that suits your usage scenario best.

Synchronous method: ExternalSign

This is a simpler method that basically lets you infiltrate into the heart of the signing routine by taking care of the hash signing operation. The class does the rest of the job (hash calculation, preparation of signature objects, CRL/OCSP retrieval).

To initiate this method, call sign_external instead of sign. When the hash is ready, it will be passed back to your code with the on_external_sign event. Your event handler needs to sign the hash with the private key and return the created signature back to the class - which will embed it into the document.

You don't need your signing certificate to contain an associated private key when using this method. The certificate itself (its public copy) may be needed though, as it is often included in the hash calculation.

This method is synchronous, meaning sign_external provides you the results immediately upon its completion.

Asynchronous method: DCAuth

DCAuth is a SecureBlackbox know-how technology. This protocol was designed to allow sharing of private keys across environments, allowing the signer and the private key to reside on different systems. It works in the following way:

The signing party - such as PDFSigner - initiates the operation using a sign_async_begin call. This produces two outcomes: a pre-signed document (a document with a blank signature placeholder), and a request state (an object containing a hash that needs to be signed). At this point the PDFSigner instance can be released, and the process itself terminated (which may be useful when run as part of a web page).
The request state is passed to the private key holder party. The private key holder passes the request state to a DCAuth object, which parses the request state, extracts the hash, and signs it. The output of DCAuth processing is another object, a response state, which contains the signature. The private key holder then sends the response state back to the signing party.
The signing party re-creates the classes and passes the response state, together with the pre-signed version of the document, to the signer's sign_async_end method. sign_async_end extracts the signature from the response state and incorporates it into the pre-signed document.

This method is asynchronous in that sense that from the signing party's viewpoint, it splits the signing operation into the pre-signing and completion stages which can be performed independently from each other and in different execution contexts. This makes this method particularly helpful for use in web pages and other scenarios where the signing key is not available in real time.

Fine-grained chain validation setup

Chain validation is a sophisticated, multi-faceted procedure that involves a lot of variables. Depending on the configuration of your operating environment, the specifics of the PKI framework being used, and the validation policy you need to follow, you may want to tune up your chain validation parameters so they fit them best. A summary of such parameters is given below.

revocation_check lets you choose between and/or prioritize revocation origins. OCSP sources are often preferred to CRL because of their real-time capability and the smaller size of validation tokens they produce.
offline_mode is a master switch that stops the class from looking for any validation tokens online. If this property is switched on, the class will only use the known_certificates, trusted_certificates, known_crls, and known_ocsps collections to look for the missing validation material.
ignore_chain_validation_errors makes the class ignore any major validation issues it encounters (such us an untrusted chain or missing CRL). This option is handy for debugging and for creating signatures in the environments where the signing certificate is not trusted.
known_certificates, known_crls, and known_ocsps let you provide your own validation material. This may be useful when working in offline_mode, where the signer has no access to the validation sources, or where the validation material has already been collected.
trusted_certificates lets you provide a list of trust anchors, either as a complement to the system's or as an alternative to it.
blocked_certificates lets you provide a list of blocked/distrusted certificates. Any CA certificate contained in it will be deemed untrusted/invalid.

The following parameters are not directly related to chain validation, but may have an implicit effect on it.

proxy, socket_settings, and tls_settings let you tune up the connectivity and TLS options in accordance with local preferences.
tls_client_chain lets you provide the client certificate and its chain for TLS client authentication.
Subscribe to on_tls_cert_validate to validate any TLS certificates of the services involved in chain validation.

The results of the chain validation procedure, upon its completion, are published in the following properties:

chain_validation_result contains the primary result of the chain validation routine: valid, valid but untrusted, invalid, or undefined.
chain_validation_details provides the details of the factors that contributed to the chain validation result, such as an outdated certificate, a missing CRL, or a missing CA certificate.
validation_log contains the detailed chain validation log. The log can often be very helpful in nailing down various validation issues.

Authority Key Identifier is a certificate extension which allows identification of certificates belonging to the same issuer, but with different public keys. It is a de-facto standard to include this extension in all certificates to facilitate chain building.

This setting cannot be set when generating a certificate as it always derives from another certificate property. CertificateManager generates this setting automatically if enough information is available to it: for self-signed certificates, this value is copied from the cert_subject_key_id setting, and for lower-level certificates, from the parent certificate's subject key ID extension.

Default Value

Remarks

Returns the type of the entity contained in the Certificate object.

A Certificate object can contain two types of cryptographic objects: a ready-to-use X.509 certificate, or a certificate request ("an unsigned certificate"). Certificate requests can be upgraded to full certificates by signing them with a CA certificate.

Use the CertificateManager class to load or create new certificate and certificate requests objects.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

Default Value

Remarks

Contains a list of locations of CRL distribution points used to check this certificate's validity. The list is taken from the respective certificate extension.

Use this property when generating a certificate to provide a list of CRL endpoints that should be made part of the new certificate.

The endpoints are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_fingerprint Property

Contains the fingerprint (a hash imprint) of this certificate.

Syntax

def get_cert_fingerprint(cert_index: int) -> str: ...

Default Value

Remarks

Contains the fingerprint (a hash imprint) of this certificate.

While there is no formal standard defining what a fingerprint is, a SHA1 hash of the certificate's DER-encoded body is typically used.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_friendly_name Property

Contains an associated alias (friendly name) of the certificate.

Syntax

def get_cert_friendly_name(cert_index: int) -> str: ...

Default Value

Remarks

Contains an associated alias (friendly name) of the certificate. The friendly name is not a property of a certificate: it is maintained by the certificate media rather than being included in its DER representation. Windows certificate stores are one example of media that does support friendly names.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_handle Property

Allows to get or set a 'handle', a unique identifier of the underlying property object.

Syntax

def get_cert_handle(cert_index: int) -> int: ...

Default Value

Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_hash_algorithm Property

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing).

Syntax

def get_cert_hash_algorithm(cert_index: int) -> str: ...

Default Value

Remarks

Provides means to set the hash algorithm to be used in the subsequent operation on the certificate (such as generation or key signing). It is not a property of a certificate; use cert_sig_algorithm to find out the hash algorithm that is part of the certificate signature.

Use the cert_key_bits, cert_curve, and cert_public_key_bytes properties to get more details about the key the certificate contains.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_key_bits Property

Returns the length of the public key in bits.

Syntax

def get_cert_key_bits(cert_index: int) -> int: ...

Default Value

Remarks

Returns the length of the public key in bits.

This value indicates the length of the principal cryptographic parameter of the key, such as the length of the RSA modulus or ECDSA field. The key data returned by the cert_public_key_bytes or cert_private_key_bytes property would typically contain auxiliary values, and therefore be longer.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_key_fingerprint Property

Returns a SHA1 fingerprint of the public key contained in the certificate.

Syntax

def get_cert_key_fingerprint(cert_index: int) -> str: ...

Default Value

Remarks

Returns a SHA1 fingerprint of the public key contained in the certificate.

Note that the key fingerprint is different from the certificate fingerprint accessible via the cert_fingerprint property. The key fingeprint uniquely identifies the public key, and so can be the same for multiple certificates containing the same key.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_key_usage Property

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

Syntax

def get_cert_key_usage(cert_index: int) -> int: ...

Default Value

Remarks

Indicates the purposes of the key contained in the certificate, in the form of an OR'ed flag set.

This value is a bit mask of the following values:


ckuUnknown	`0x00000`	Unknown key usage
ckuDigitalSignature	`0x00001`	Digital signature
ckuNonRepudiation	`0x00002`	Non-repudiation
ckuKeyEncipherment	`0x00004`	Key encipherment
ckuDataEncipherment	`0x00008`	Data encipherment
ckuKeyAgreement	`0x00010`	Key agreement
ckuKeyCertSign	`0x00020`	Certificate signing
ckuCRLSign	`0x00040`	Revocation signing
ckuEncipherOnly	`0x00080`	Encipher only
ckuDecipherOnly	`0x00100`	Decipher only
ckuServerAuthentication	`0x00200`	Server authentication
ckuClientAuthentication	`0x00400`	Client authentication
ckuCodeSigning	`0x00800`	Code signing
ckuEmailProtection	`0x01000`	Email protection
ckuTimeStamping	`0x02000`	Timestamping
ckuOCSPSigning	`0x04000`	OCSP signing
ckuSmartCardLogon	`0x08000`	Smartcard logon
ckuKeyPurposeClientAuth	`0x10000`	Kerberos - client authentication
ckuKeyPurposeKDC	`0x20000`	Kerberos - KDC

Set this property before generating the certificate to propagate the key usage flags to the new certificate.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_key_valid Property

Returns True if the certificate's key is cryptographically valid, and False otherwise.

Syntax

def get_cert_key_valid(cert_index: int) -> bool: ...

Default Value

FALSE

Remarks

Returns True if the certificate's key is cryptographically valid, and False otherwise.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_ocsp_locations Property

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Syntax

def get_cert_ocsp_locations(cert_index: int) -> str: ...

Default Value

Remarks

Locations of OCSP services that can be used to check this certificate's validity in real time, as recorded by the CA.

Set this property before calling the certificate manager's generate method to propagate it to the new certificate.

The OCSP locations are provided as a list of CRLF-separated URLs. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the location separator.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_ocsp_no_check Property

Accessor to the value of the certificate's ocsp-no-check extension.

Syntax

def get_cert_ocsp_no_check(cert_index: int) -> bool: ...

Default Value

FALSE

Remarks

Accessor to the value of the certificate's ocsp-no-check extension.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_origin Property

Returns the location that the certificate was taken or loaded from.

Syntax

def get_cert_origin(cert_index: int) -> int: ...

Default Value

Remarks

Returns the location that the certificate was taken or loaded from.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_policy_i_ds Property

Contains identifiers (OIDs) of the applicable certificate policies.

Syntax

def get_cert_policy_i_ds(cert_index: int) -> str: ...

Default Value

Remarks

Contains identifiers (OIDs) of the applicable certificate policies.

The Certificate Policies extension identifies a sequence of policies under which the certificate has been issued, and which regulate its usage.

Set this property when generating a certificate to propagate the policies information to the new certificate.

The policies are provided as a list of CRLF-separated entries. Note that this differs from the behaviour used in earlier product versions, where the "|" character was used as the policy element separator.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_private_key_bytes Property

Returns the certificate's private key in DER-encoded format.

Syntax

def get_cert_private_key_bytes(cert_index: int) -> bytes: ...

Remarks

Returns the certificate's private key in DER-encoded format. It is normal for this property to be empty if the private key is non-exportable, which, for example, is typical for certificates originating from hardware security devices.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_private_key_exists Property

Indicates whether the certificate has a usable private key associated with it.

Syntax

def get_cert_private_key_exists(cert_index: int) -> bool: ...

Default Value

FALSE

Remarks

Indicates whether the certificate has a usable private key associated with it. If it is set to True, the certificate can be used for private key operations, such as signing or decryption.

This property is independent from cert_private_key_bytes, and can be set to True even if the former is empty. This would imply that the private key is non-exportable, but still can be used for cryptographic operations.

The cert_index parameter specifies the index of the item in the array. The size of the array is controlled by the cert_count property.

This property is read-only.

cert_private_key_extractable Property

revocation_check = property(get_revocation_check, set_revocation_check)

Default Value

Remarks

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

Certificate Revocation Lists (CRLs) and Online Certificate Status Protocol (OCSP) responses serve the same purpose of ensuring that the certificate had not been revoked by the Certificate Authority (CA) at the time of use. Depending on your circumstances and security policy requirements, you may want to use either one or both of the revocation information source types.


crcNone	`0`	No revocation checking
crcAuto	`1`	Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future.
crcAllCRL	`2`	Check all provided CRL endpoints for all chain certificates.
crcAllOCSP	`3`	Check all provided OCSP endpoints for all chain certificates.
crcAllCRLAndOCSP	`4`	Check all CRL and OCSP endpoints for all chain certificates.
crcAnyCRL	`5`	At least one CRL check for every certificate in the chain must succeed.
crcAnyOCSP	`6`	At least one OCSP check for every certificate in the chain must succeed.
crcAnyCRLOrOCSP	`7`	At least one CRL or OCSP check for every certificate in the chain must succeed. CRL endpoints are checked first.
crcAnyOCSPOrCRL	`8`	At least one CRL or OCSP check for every certificate in the chain must succeed. OCSP endpoints are checked first.

This setting controls the way the revocation checks are performed. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Syntax

def get_widget_background_mask() -> bytes: ...
def set_widget_background_mask(value: bytes) -> None: ...

widget_background_mask = property(get_widget_background_mask, set_widget_background_mask)

Remarks

Contains the background image mask.

Masks provide a means for marking transparent areas on your signature widgets. Specifically, a transparency mask tells PDF viewing apps which pixels of the signature widget should be kept visible and which should be rendered transparent instead.

In most cases, you will need a unique mask that is tailored for your signature widget image. This is something that you will need to create yourself based on your preferences and the actual image design.

A mask is effectively a matrix of bits, with each bit corresponding to a pixel on your background bitmap. A bit is set to 1 if the corresponding pixel needs to be made transparent, or to 0 if it needs to be opaque.

To create the mask that can be passed to BackgroundMask, please follow the below procedure:

Go through your signature widget bitmap row by row, processing each row of pixels from left to right. For each row,

1. Start with an empty bit string.

2. For every pixel in a row, add a '1' bit if you want it to be transparent, or a '0' bit if you want it to be opaque.

3. Upon reaching the end of the row, append '0' bits to your bit string until the number of bits in it is a multiple of 8. This is because each row of pixels needs to be represented with a whole number of bytes.

4. Convert the bit string to a byte array by grouping every 8 bits into a byte.

Do the same for every row of pixels, and then concatenate the received byte arrays together. Pass the created byte array to BackgroundMask.

A small example. Imagine your image is 19 pixels wide and 3 pixels tall. Imagine you want to make it 'semi-transparent' by using a 'mesh' pattern. The mask will therefore look like this:

10101010 10101010 10100000 // first row

01010101 01010101 01000000 // second row

10101010 10101010 10100000 // third row

Note that the last 5 bits of each row are padding '0' bits and are ignored: you only need them to make each row contain a whole number of bytes. When converted to a byte string, this would look like

0xAA 0xAA 0xA0

0x55 0x55 0x40

0xAA 0xAA 0xA0

, or, if written as a byte array, (0xAA, 0xAA, 0xA0, 0x55, 0x55, 0x40, 0xAA, 0xAA, 0xA0): this is what you need to pass to BackgroundMask.

	"FontName"	The font name or TrueType filename. It supports the same values as the Widget.FontName property.

The method returns the index of the new custom text in the CustomText collection (accessed via config).

attach_bytes Method

Adds an attachment to the PDF document.

Syntax

def attach_bytes(data: bytes, obj_name: str, file_name: str, description: str, sub_type: str, c_date: str, m_date: str) -> None: ...

Remarks

Use this method to add an attachment (embedded file) to a PDF document.

attach_file Method

Adds an attachment to the PDF document.

Syntax

def attach_file(path: str, obj_name: str, file_name: str, description: str, sub_type: str, c_date: str, m_date: str) -> None: ...

Remarks

Use this method to add an attachment (embedded file) to a PDF document.

close Method

Closes an opened document.

Syntax

def close(save_changes: bool) -> None: ...

Remarks

Use this method to close a previously opened document. Set SaveChanges to true to apply any changes made.

config Method

This 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_action Method

Performs an additional action.

Syntax

def do_action(action_id: str, action_params: str) -> str: ...

Remarks

do_action is a generic method available in every class. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

Supported ActionIDs:


	"AddImage"	Adds an image to the foreground layer.
	"GetTextWidth"	Calculates the width of the given text for a specific font.
	"GetSystemFontNames"	Gets the list of system font names.
	"IsAllGlyphsAvailable"	Checks if all glyphs from the given text are available for a specific font.

Use "AddImage" action to add an image to the foreground layer. The following parameters are supported:


	"ImageData"	The image data in hex or base64 encoding. To use base64 encoding prepend an encoded data with "base64:" prefix.
	"ImageWidth"	The width of the image in pixels.
	"ImageHeight"	The height of the image in pixels.
	"ImageType"	The type of the image contained in ImageData parameter. Supported values: "jpeg", "jpeg2000", "custom".
	"ImageBitsPerComponent"	The number of bits per color space component for the image.
	"ImageColorSpace"	The image color space. Supported values: "RGB", "CMYK" and "Gray".
	"ImageInterpolate"	Specifies whether an image interpolation shall be performed by a conforming reader.
	"X"	The image offset from the left-hand signature widget border.
	"Y"	The image offset from the bottom signature widget border.
	"Width"	The width of the image in points.
	"Height"	The height of the image in points.

Parameters ImageData, ImageWidth, ImageHeight, ImageType, X, Y, Width and Height are required.

Sample code to add a JPEG image of size 100px x 100px and place it in position (10, 10) with an image size (30, 30): Signer.DoAction("AddImage", "ImageData=" + Utils.HexEncode(BinaryImageData) + "; ImageWidth=100; ImageHeight=100; ImageType=jpeg; X=10; Y=10; Width=30; Height=30");

Use "GetTextWidth" action to calculate the width of the given text for a specific font. The following parameters are supported:


	"Text"	Represent the text string for which you want to determine the width.
	"FontName"	The font name or TrueType filename. It supports the same values as Widget.FontName property.
	"FontSize"	The horizontal font size of the text. If omitted, the width of the text returned in units, and the width for a specific font size could be calculated by the formula: (Width / 1000) * FontSize

Sample code: Signer.DoAction("GetTextWidth", "Text=Lorem Ipsum; FontSize=10; FontName=Arial Bold Italic");

Use "GetSystemFontNames" action to get a CRLF-separated list of system TrueType font names that the component supports.

Use "IsAllGlyphsAvailable" action to check if all glyphs that correspond to the given text are available for a specific font. The following parameters are required:


	"Text"	Represent the text string that you want to check.
	"FontName"	The font name or TrueType filename. It supports the same values as Widget.FontName property.

For standard Type 1 fonts this action always returns a "true" value.

extract_async_data Method

Extracts user data from the DC signing service response.

Syntax

def extract_async_data(async_reply: str) -> str: ...

Remarks

Call this method before finalizing the asynchronous signing process to extract the data passed to the ExternalCrypto.Data property on the pre-signing stage.

The Data parameter can be used to pass some state or document identifier along with the signing request from the pre-signing to the completion async stage.

get_attached_bytes Method

Saves a PDF attachment to a byte array.

Syntax

def get_attached_bytes(index: int) -> bytes: ...

Remarks

Use this method to retrieve the contents of an attached file as a byte array.

get_attached_file Method

Syntax

def get_attached_file(index: int, path: str) -> None: ...

Remarks

Use this method to retrieve the contents of an attached file and save it to a file.

open Method

Opens a document for signing or updating.

Syntax

def open() -> None: ...

Remarks

Use this method to open a document for signing or updating. When finished, call close to complete or discard the operation.

reset Method

Resets the class settings.

Syntax

def reset() -> None: ...

Remarks

reset is a generic method available in every class.

revalidate Method

Revalidates a signature in accordance with current settings.

Syntax

def revalidate(sig_label: str) -> None: ...

Remarks

Use this method to re-validate a signature in the opened PDF document.

select_info Method

TBD.

Syntax

def select_info(entity_label: str, info_type: int, clear_selection: bool) -> None: ...

Remarks

TBD

sign Method

Signs a PDF document.

Syntax

def sign() -> None: ...

Remarks

Call this method to sign the document referenced by the input_file (or input_stream) property. The document will be signed with signing_certificate as configured in new_signature, and saved in output_file (output_stream).

Use trusted_certificates, known_certificates, revocation_check, offline_mode and other properties of the class to adjust chain validation parameters. After the signing, the chain validation log will be available in the property.

sign_async_begin Method

Initiates the asynchronous signing operation.

Syntax

def sign_async_begin() -> str: ...

Remarks

When using the DC framework, call this method to initiate the asynchronous signing process. Upon completion, a pre-signed copy of the document will be saved in output_file (or output_stream). Keep the pre-signed copy somewhere local, and pass the returned string ('the request state') to the DC processor for handling.

Upon receiving the response state from the DC processor, assign the path to the pre-signed copy to input_file (or input_stream), and call sign_async_end to finalize the signing.

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the signing_certificate property.

Use the ExternalCrypto.AsyncDocumentID property to supply a unique document ID to include in the request. This is helpful when creating batches of multiple async requests, as it allows you to pass the whole response batch to sign_async_end and expect it to recover the correct response from the batch automatically.

AsyncState is a message of the distributed cryptography (DC) protocol. The DC protocol is based on the exchange of async states between a DC client (an application that wants to sign a PDF, XML, or Office document) and a DC server (an application that controls access to the private key). An async state can carry one or more signing requests, comprised of document hashes, or one or more signatures produced over those hashes.

In a typical scenario you get a client-side async state from the sign_async_begin method. This state contains document hashes to be signed on the DC server side. You then send the async state to the DC server (often represented by the DCAuth class), which processes it and produces a matching signature state. The async state produced by the server is then passed to the sign_async_end method.

There are some conditions that should be met when signing PDF documents asynchronously. The advanced PDF signature levels, specifically BES, EPES, and LTV, require that the 'signingCertificate' attribute is included in the signature. This can only be satisfied if either external_crypto is configured to use the asmdPKCS7 method, or the public copy of the signing certificate is provided on the pre-signing stage.

Please note that you will still be able to sign a document with the asmdPKCS1 method and no public copy of the certificate provided (resulting in the omission of the 'signingCertificate' attribute from the signature); however, most modern PDF processors will reject such signatures as invalid or non-compliant.

sign_async_end Method

Completes the asynchronous signing operation.

Syntax

def sign_async_end(async_reply: str) -> None: ...

Remarks

When using the DC framework, call this method upon receiving the response state from the DC processor to complete the asynchronous signing process.

Before calling this method, assign the path to the pre-signed copy of the document obtained from the prior sign_async_begin call to input_file (or input_stream). The method will embed the signature into the pre-signed document, and save the complete signed document to output_file (or output_stream).

Note that depending on the signing method and DC configuration used, you may still need to provide the public part of the signing certificate via the signing_certificate property.

Use the ExternalCrypto.AsyncDocumentID parameter to pass a specific document ID if using batched AsyncReply. If used, it should match the value provided on the pre-signing (sign_async_begin) stage.

sign_external Method

Signs the document using an external signing facility.

Syntax

def sign_external() -> None: ...

Remarks

Use this method to create a PDF signature using an external signing facility for the cryptographic computations. SignExternal delegates the low-level signing operation to an external, remote, or custom signing engine. This method is useful if the signature has to be made by a device accessible through a custom or non-standard signing interface.

When all preparations are done and the hash is computed, the class fires the on_external_sign event which allows the hash value to be passed for signing.

update Method

Updates a signature.

Syntax

def update(sig_label: str) -> None: ...

Remarks

PDF signatures may be updated from time to time by embedding newer/missing revocation information. The update approach is typically used to extend the validity of an LTV signature. Set SigLabel to the label of the signature field to update.

Updating is typically accompanied with a document timestamping operation. Set timestamp_server to have the class obtain and embed a document timestamp for you.

Before calling this method, provide the signed document via the input_file (or input_stream) property. The updated document will be saved to output_file (or output_stream).

on_chain_element_download Event

on_chain_validation_progress Event

This event is fired multiple times during chain validation to report various stages of the validation procedure.

Syntax

class PDFSignerChainValidationProgressEventParams(object):
  @property
  def event_kind() -> str: ...

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

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

  @property
  def action() -> int: ...
  @action.setter
  def action(value) -> None: ...

# In class PDFSigner:
@property
def on_chain_validation_progress() -> Callable[[PDFSignerChainValidationProgressEventParams], None]: ...
@on_chain_validation_progress.setter
def on_chain_validation_progress(event_hook: Callable[[PDFSignerChainValidationProgressEventParams], None]) -> None: ...

Remarks

Subscribe to this event to be notified about chain validation progress. Use the Action parameter to alter the validation flow.

The EventKind parameter reports the nature of the event being reported. The CertRDN and CACertRDN parameters report the distinguished names of the certificates that are relevant for the event invocation (one or both can be empty, depending on EventKind). Use the Action parameter to adjust the validation flow.


veaAuto	`0`	Handle the action automatically (the default behaviour)
veaContinue	`1`	Accept the request implied by the event (accept the certificate, allow the object retrieval)
veaReject	`2`	Reject the request implied by the event (reject the certificate, disallow the object retrieval)
veaAcceptNow	`3`	Accept the validated certificate immediately
veaAbortNow	`4`	Abort the validation, reject the certificate

on_document_loaded Event

This event is fired when the document has been loaded into memory.

Syntax

class PDFSignerDocumentLoadedEventParams(object):
  @property
  def cancel() -> bool: ...
  @cancel.setter
  def cancel(value) -> None: ...

# In class PDFSigner:
@property
def on_document_loaded() -> Callable[[PDFSignerDocumentLoadedEventParams], None]: ...
@on_document_loaded.setter
def on_document_loaded(event_hook: Callable[[PDFSignerDocumentLoadedEventParams], None]) -> None: ...

Remarks

The handler for this event is a good place to check the document structure, which may be useful when preparing the signature. For example, you can use the pages information to find the optimal position for the signature widget.

Set Cancel to true to terminate document processing on this stage.

on_encrypted Event

Notifies the application that the document is encrypted and provides recipient certificate details if asymmetric encryption was used to encrypt the document.

Syntax

class PDFSignerEncryptedEventParams(object):
  @property
  def cert_used() -> bool: ...

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

  @property
  def serial_number() -> bytes: ...

  @property
  def subject_key_id() -> bytes: ...

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

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

# In class PDFSigner:
@property
def on_encrypted() -> Callable[[PDFSignerEncryptedEventParams], None]: ...
@on_encrypted.setter
def on_encrypted(event_hook: Callable[[PDFSignerEncryptedEventParams], None]) -> None: ...

Remarks

The class fires this event when processing encrypted documents to report the fact of encryption and pass certificate parameters to the user.

This event fires repeatedly for each encryption mechanism used in the document until the user provides the correct credential via the decryption_certificate or password property (depending on the encryption method used), or sets SkipThis to true.

The CertUsed parameter specifies the encryption method used. If set to true, it indicates that the document uses asymmetric (certificate-based) encryption. In that case, the IssuerRDN, SerialNumber, and SubjectKeyID parameters provide the details of the encryption certificate. Note that the document can be encrypted with more than one certificate (or have "more than one recipient"), in which case each certificate will invoke its own on_encrypted event loop.

CertUsed set to false indicates that the document uses password encryption. In this case, provide the password via the password property.

The NeedCredential parameter specifies whether the correct credential is already available to the class or still needs to be set. One example where NeedCredential would be set to false is where it had been provided by the application prior to processing the document (e.g. by setting the password property to a known pre-defined value). If NeedCredential is set to true, you must provide the valid credential for the decryption process to succeed.

on_error Event

Information about errors during signing/validation.

Syntax

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

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

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

Remarks

The event is fired in case of exceptional conditions during PDF processing.

ErrorCode contains an error code and Description contains a textual description of the error.

on_external_decrypt Event

Handles remote or external decryption.

Syntax

class PDFSignerExternalDecryptEventParams(object):
  @property
  def operation_id() -> str: ...

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

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

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

  @property
  def data() -> str: ...
  @data.setter
  def data(value) -> None: ...

# In class PDFSigner:
@property
def on_external_decrypt() -> Callable[[PDFSignerExternalDecryptEventParams], None]: ...
@on_external_decrypt.setter
def on_external_decrypt(event_hook: Callable[[PDFSignerExternalDecryptEventParams], None]) -> None: ...

Remarks

Assign a handler to this event if you need to delegate a low-level decryption operation to an external, remote, or custom decryption engine. The handler receives an encrypted value in the EncryptedData parameter, and is expected to decrypt it and place the decrypted value into the Data parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. Algorithm specifies the encryption algorithm being used, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the EncryptedData, Data, and Pars parameters. If your decryption engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the decryption.

Sample data encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

on_external_sign Event

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

class PDFSignerExternalSignEventParams(object):
  @property
  def operation_id() -> str: ...

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

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

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

  @property
  def signed_data() -> str: ...
  @signed_data.setter
  def signed_data(value) -> None: ...

# In class PDFSigner:
@property
def on_external_sign() -> Callable[[PDFSignerExternalSignEventParams], None]: ...
@on_external_sign.setter
def on_external_sign(event_hook: Callable[[PDFSignerExternalSignEventParams], None]) -> None: ...

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the class via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact class being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The class uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

on_notification Event

This event notifies the application about an underlying control flow event.

Syntax

class PDFSignerNotificationEventParams(object):
  @property
  def event_id() -> str: ...

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

# In class PDFSigner:
@property
def on_notification() -> Callable[[PDFSignerNotificationEventParams], None]: ...
@on_notification.setter
def on_notification(event_hook: Callable[[PDFSignerNotificationEventParams], None]) -> None: ...

Remarks

The class fires this event to let the application know about some event, occurrence, or milestone in the class. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the class, the exact action it is performing, or the document being processed, one or both may be omitted.

This class can fire this event with the following EventID values:


DocumentLoaded	Reports the completion of PDF document processing by the component. Use the event handler to access document-related information, such as page number and document file details. The EventParam value passed with this EventID is empty.
BeforeTimestamp	This event is fired before a timestamp is requested from the timestamping authority. Use the event handler to modify TSA and HTTP settings.
TimestampError	This event is only fired if the class failed to obtain a timestamp from the timestamping authority. The EventParam parameter contains extended error info.
TimestampRequest	A timestamp is requested from the custom timestamping authority. This event is only fired if timestamp_server was set to a virtual:// URI. The EventParam parameter contains the TSP request (or the plain hash, depending on the value provided to timestamp_server), in base16, that needs to be sent to the TSA. Use the event handler to send the request to the TSA. Upon receiving the response, assign it, in base16, to the TimestampResponse configuration property.
SignatureWidgetPrepare	Another copy of the signature widget needs to be configured. Use the event handler to configure individual widgets when creating multi-widget signatures. The on_notification event with this event ID will be fired repeatedly until the LastSignatureWidget configuration setting is set to true. The EventParam value passed with this EventID is empty.

on_pre_render_widget Event

Fires when a signature widget is ready to be written to the document.

Syntax

class PDFSignerPreRenderWidgetEventParams(object):
  @property
  def add_another() -> bool: ...
  @add_another.setter
  def add_another(value) -> None: ...

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

# In class PDFSigner:
@property
def on_pre_render_widget() -> Callable[[PDFSignerPreRenderWidgetEventParams], None]: ...
@on_pre_render_widget.setter
def on_pre_render_widget(event_hook: Callable[[PDFSignerPreRenderWidgetEventParams], None]) -> None: ...

Remarks

The class fires this event when it is ready to insert a new instance of the signature widget to the document. This event is fired repeatedly until the event handler sets the AddAnother parameter to false, allowing your application to create as many copies of the signature widget as required.

You can use this event handler to adjust the look of each widget copy. Set the ResetAnother parameter to true to automatically clean up all the existing widget settings after the current widget is saved. Setting ResetAnother to true will let you start every new widget from scratch. Keeping it set to false would result in every new widget looking the same as the previous one.

on_signature_found Event

Signifies the start of signature validation.

Syntax

class PDFSignerSignatureFoundEventParams(object):
  @property
  def index() -> int: ...

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

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

  @property
  def serial_number() -> bytes: ...

# In class PDFSigner:
@property
def on_signature_found() -> Callable[[PDFSignerSignatureFoundEventParams], None]: ...
@on_signature_found.setter
def on_signature_found(event_hook: Callable[[PDFSignerSignatureFoundEventParams], None]) -> None: ...

Remarks

This event tells the application that signature validation is about to start, and provides the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters. It fires for every signature located in the verified document or message.

The CertFound parameter is set to True if the class has found the needed certificate in one of the known locations, and to False otherwise, in which case you must provide it manually via the known_certificates property.

Signature validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the and properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

on_signature_validated Event

Marks the completion of the signature validation routine.

Remarks

This event is fired upon the completion of the signature validation routine, and reports the respective validation result.

Use the IssuerRDN, SerialNumber, and/or SubjectKeyID parameters to identify the signing certificate.

ValidationResult is set to 0 if the validation has been successful, or to a non-zero value in case of a validation failure.


svtValid	`0`	The signature is valid
svtUnknown	`1`	Signature validity is unknown
svtCorrupted	`2`	The signature is corrupted
svtSignerNotFound	`3`	Failed to acquire the signing certificate. The signature cannot be validated.
svtFailure	`4`	General failure
svtReferenceCorrupted	`5`	Reference corrupted (XML-based signatures only)

on_timestamp_found Event

Signifies the start of a timestamp validation routine.

Syntax

class PDFSignerTimestampFoundEventParams(object):
  @property
  def index() -> int: ...

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

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

def on_timestamp_found() -> Callable[[PDFSignerTimestampFoundEventParams], None]: ...
@on_timestamp_found.setter
def on_timestamp_found(event_hook: Callable[[PDFSignerTimestampFoundEventParams], None]) -> None: ...

Remarks

This event fires for every timestamp identified during signature processing, and reports the details about the signer's certificate via its IssuerRDN, SerialNumber, and SubjectKeyID parameters.

Just like with signature validation, timestamp validation consists of two independent stages: cryptographic signature validation and chain validation. Separate validation results are reported for each, with the and properties respectively.

Use the ValidateSignature and ValidateChain parameters to tell the verifier which stages to include in the validation.

on_timestamp_request Event

Fires when the class is ready to request a timestamp from an external TSA.

Syntax

class PDFSignerTimestampRequestEventParams(object):
  @property
  def tsa() -> str: ...

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

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

def on_timestamp_request(event_hook: Callable[[PDFSignerTimestampRequestEventParams], None]) -> None: ...

Remarks

Subscribe to this event to intercept timestamp requests. You can use it to override timestamping requests and perform them in your code.

The TSA parameter indicates the timestamping service being used. It matches the value passed to the timestamp_server property. Set the SuppressDefault parameter to false if you would like to stop the built-in TSA request from going ahead. The built-in TSA request is also not performed if the returned TimestampResponse parameter is not empty.

on_timestamp_validated Event

Syntax

class PDFSignerTLSCertNeededEventParams(object):
  @property
  def host() -> str: ...

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

# In class PDFSigner:
@property
def on_tls_cert_needed() -> Callable[[PDFSignerTLSCertNeededEventParams], None]: ...
@on_tls_cert_needed.setter
def on_tls_cert_needed(event_hook: Callable[[PDFSignerTLSCertNeededEventParams], None]) -> None: ...

Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The Host parameter identifies the host that makes a request, and the CANames parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the tls_client_chain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the on_tls_handshake event for the given host and, if the certificate was accepted, succeeded by the on_tls_established event.

on_tls_cert_validate Event

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Syntax

class PDFSignerTLSCertValidateEventParams(object):
  @property
  def server_host() -> str: ...

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

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

# In class PDFSigner:
@property
def on_tls_cert_validate() -> Callable[[PDFSignerTLSCertValidateEventParams], None]: ...
@on_tls_cert_validate.setter
def on_tls_cert_validate(event_hook: Callable[[PDFSignerTLSCertValidateEventParams], None]) -> None: ...

Remarks

This event is fired during a TLS handshake. Use the tls_server_chain property to access the certificate chain. In general, classes may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the class, and can be adjusted if needed.

on_tls_established Event

Fires when a TLS handshake with Host successfully completes.

Syntax

class PDFSignerTLSEstablishedEventParams(object):
  @property
  def host() -> str: ...

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

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

  @property
  def connection_id() -> bytes: ...

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

# In class PDFSigner:
@property
def on_tls_established() -> Callable[[PDFSignerTLSEstablishedEventParams], None]: ...
@on_tls_established.setter
def on_tls_established(event_hook: Callable[[PDFSignerTLSEstablishedEventParams], None]) -> None: ...

Remarks

The class uses this event to notify the application about a successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate the security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.

on_tls_handshake Event

Fires when a new TLS handshake is initiated, before the handshake commences.

Syntax

class PDFSignerTLSHandshakeEventParams(object):
  @property
  def host() -> str: ...

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

# In class PDFSigner:
@property
def on_tls_handshake() -> Callable[[PDFSignerTLSHandshakeEventParams], None]: ...
@on_tls_handshake.setter
def on_tls_handshake(event_hook: Callable[[PDFSignerTLSHandshakeEventParams], None]) -> None: ...

Remarks

The class uses this event to notify the application about the start of a new TLS handshake to Host. If the handshake is successful, this event will be followed by the on_tls_established event. If the server chooses to request a client certificate, the on_tls_cert_needed event will also be fired.

on_tls_shutdown Event

Reports the graceful closure of a TLS connection.

Syntax

class PDFSignerTLSShutdownEventParams(object):
  @property
  def host() -> str: ...

# In class PDFSigner:
@property
def on_tls_shutdown() -> Callable[[PDFSignerTLSShutdownEventParams], None]: ...
@on_tls_shutdown.setter
def on_tls_shutdown(event_hook: Callable[[PDFSignerTLSShutdownEventParams], None]) -> None: ...

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

PDFSigner 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.

This indexed setting provides access to the horizontal compound of the custom text font size.

CustomTextFontSizeY[Index]: The vertical font size scale.

This indexed setting provides access to the vertical compound of the custom text font size.

CustomTextText[Index]: A text to show on a custom signature widget text block.

This indexed setting provides access to the text to be placed on a specific signature widget text block. CustomTextText[0] specifies the text on the first block, CustomTextText[1] on the second block, and so on. Use the CustomTextCount property to get or set the number of custom text blocks.

This indexed setting provides access to the vertical offset of the custom text block on the widget.

DateFontSize: The font size of the date/time text on the signature widget.

Use this property to specify the font size to be used for the date/time text on the signature widget.

DeepValidation: Whether a complete validation should be performed.

If this property is switched on, a "deep" signature validation is performed, i.e., all certificate chains are validated, and all revocation checks are performed.

DislikeOpenEndedOCSPs: Tells the class to discourage OCSP responses without an explicit NextUpdate parameter.

When this property is set to True, the validation engine treats OCSP response without a NextUpdate field as 'substandard' and tries to obtain some further revocation material for the certificate in question (a different OCSP or a CRL, even if the class is configured to prefer the OCSP route). This is to work around Adobe Reader's intolerance to such OCSPs when classifying signed documents as LTV (as of August 2022).

EmptyFullFieldName: Specifies the full name of the empty signature field to sign.

Use this property to specify the empty form field that should be signed. If the default value of "" is assigned to this property or the default value of -1 is assigned to the empty_field_index property, then a new signature field will be created.

EmptySignatureFieldRequiredReasons[Index]: Specifies the required reasons.

This property contains the required reasons used for signature generation.

EmptySignatureFieldRequiredSubfilters[Index]: Specifies the required subfilters.

This property contains the list of subfilters required by the signature. A subfilter represents the encoding to use when signing the PDF form.

EmptySignatureFieldTimestampRequired[Index]: Specifies if the signature should be timestamped.

This property contains True if the signature should be timestamped.

EmptySignatureFieldTSPURL[Index]: URL for a TSP server.

This property contains the TSP server URL.

Use this property to allocate extra zero character space in the document behind the signature. The allocated space can be used in the future to place a timestamp.

FontPaths: Specifies font search paths.

Use this property to provide a CRLF-separated list of paths where TrueType font files should be searched. The default value is the system font search paths.

ForceCompleteChainValidation: Whether to check issuer (CA) certificates when the signing certificate is invalid.

Specifies whether to check issuer (CA) certificates when the signing certificate is invalid.

ForceCompleteChainValidationForTrusted: Whether to continue with the full validation up to the root CA certificate for mid-level trust anchors.

Set this property to True to enable full chain validation for explicitly trusted intermediary or end-entity certificates. This may be useful when creating signatures to enforce completeness of the collected revocation information. It often makes sense to set this property to false when validating signatures to reduce validation time and avoid issues with badly configured environments.

GracePeriod: Specifies a grace period to apply during revocation information checks.

Use this property to specify a grace period (in seconds). The grace period applies to certain subprotocols, such as OCSP, and caters to the inaccuracy and/or missynchronization of clocks on different participating systems. Any time deviations within the grace period will be tolerated.

HardenedKeyGeneration: Specifies if hardened Key generation should be used.

Specifies if hardened Key generation should be used when the AES-256 encryption algorithm and password encryption are used.

IgnoreChainLoops: Whether chain loops should be ignored.

Set this property to True to make the validation engine ignore chain loops. This may be an option when you need to process chains from buggy CAs that happen to include subchains that sign themselves.

IgnoreOCSPNoCheckExtension: Whether the OCSP NoCheck extension should be ignored.

Set this property to True to make the validation engine ignore the OCSP no-check extension. You would normally need to set this property when validating severely non-compliant chains that misuse the extension, causing chain loops or other validation issues.

IgnoreSystemTrust: Whether trusted Windows Certificate Stores should be treated as trusted.

Specifies whether, during chain validation, the class should respect the trust to CA certificates as configured in the operating system. In Windows this effectively defines whether the class should trust the certificates residing in the Trusted Root Certification Authorities store.

If IgnoreSystemTrust is True, certificates residing in the trusted root store are treated as if they are known, rather than trusted. Only certificates provided via other means (such as the trusted_certificates property) are considered trusted.

IgnoreTimestampFailure: Whether to ignore timestamping failures during signing.

Specifies whether to ignore timestamping failures during signing.

ImplicitlyTrustSelfSignedCertificates: Whether to trust self-signed certificates.

Set this property to True to implicitly trust all self-signed certificates. Use it with care as trusting just about every self-signed certificate is unwise. One exceptional reason where this property may be handy is where a chain is validated in an environment that is not supposed to trust it (for example, a signing, rather than verifying environment, or a QA server). Trusting all self-signing certificates (which are normally trusted) allows emulating the verifying environment without actually changing its security settings.

IncludeKnownRevocationInfoToSignature: Whether to include custom revocation info into the signature.

This property specifies whether revocation pieces provided via the known_certificates, known_crls, and known_ocsps properties should be included into the signature. This property lets you include custom validation elements to the signature in addition to the ones comprising the signing chain.

IncludeRevocationInfoToAdbeAttribute: Whether to save revocation info in PDF-compliant form.

The format of revocation info in AdES signatures does not comply with PDF standards. If this property is switched on, the revocation info will be saved in PDF-compliant form.

LastSignatureWidget: Specifies that it is the last signature widget to be added.

Set this property to False to add one more signature widget along with the signature.

This setting is used by the on_notification event when the EventID parameter is "SignatureWidgetPrepare" to allow support for multi-widget signatures.

PAdESOptions: Specifies the PAdES options.

Contains a comma-separated list of values that specify the PAdES options.

Supported values are:


UseSigningCertificateV2		When this flag is set, the signing certificate V2 attribute will be used.
IncludeAllRevInfoToDSS		When this flag is set, the full set of revocation information will be included in the DSS dictionary.
CreateVRIDictionaries		When this flag is set, VRI dictionaries will be created. A VRI dictionary references all the validation data that has been used for validating one specific signature.
UseUndefBEREncoding		When this flag is set, ASN.1 tags with undefined sizes are allowed in the signature.
TolerateMissingSigningCertificate		When this flag is set, a missing signing certificate attribute will be tolerated.
CompressDSS		When this flag is set, content in DSS dictionary will be compressed.
CreatePBADCompatibleSignature		When this flag is set, the PBAD.PAdES compatible signature is created.
EnforcePDFACompliance		When this flag is set, the component will enforce PDF/A compliance during signing. In rare cases this may lead to exceptions being thrown if the signing chain is too heavy to fit into the PDF/A restrictions.

TLSClientAuthRequested: Indicates whether the TLS server requests client authentication.

Check this property in the TLSCertValidate event handler to find out whether the TLS server requests the client to provide the authentication certificate. If this property is set to true, provide your certificate via the TLSClientChain property. Note that the class may fire this event more than once during each operation, as more than one TLS-enabled server may need to be contacted.

TLSValidationLog: Contains the log of the TLS server certificate validation.

Check this property in the TLSCertValidate event handler to retrieve the validation log of the TLS server.

TolerateMinorChainIssues: Whether to tolerate minor chain issues.

This parameter controls whether the chain validator should tolerate minor technical issues when validating the chain. Those are:

CA, revocation source, TLS key usage requirements are not mandated
Violation of OCSP issuer requirements are ignored
The AuthorityKeyID extension in CRL- and certificate-issuing CAs are ignored (helps with incorrectly renewed certificates)
Basic constraints and name constraints of CA certificates are ignored
Some weaker algorithms are tolerated

UpdateKind: Adjusts the scope of modifications that are made to the signature with the Update method.

This property adjusts the kind of modifications to the document that an Update() call makes.

With this property set to the default setting (default), Update() refreshes the validation details included in the signature using any available revocation information sources. It also seals the added elements with a Document Timestamp if the TSA is provided through the timestamp_server property.

The only alternative setting is TimestampOnly, which instructs Update() to only timestamp the updated non-timestamped signature with a signature timestamp. No validation information collection is performed and no Document Timestamp is added. The TimestampOnly variant requires the timestamp_server property to be set.

UseLegacyVisualStyle: Specifies whether to use the legacy signature visual style.

Set this property to False to use the new signature visual style.

UseMicrosoftCTL: Enables or disables the automatic use of the Microsoft online certificate trust list.

Enable this property to make the chain validation module automatically look up missing CA certificates in the public Windows Update repository.

UsePSS: Whether to use the RSASSA-PSS algorithm.

Although the RSASSA-PSS algorithm provides better security than a classic RSA scheme (PKCS#1-1.5), please take into account that RSASSA-PSS is a relatively new algorithm which may not be understood by older implementations.

UseSystemCertificates: Enables or disables the use of the system certificates.

Use this property to tell the chain validation module to automatically look up missing CA certificates in the system certificates. In many cases it is beneficial to switch this property on, as the operating system certificate configuration provides a representative trust framework.

UseValidationCache: Enables or disable the use of the product-wide certificate chain validation cache.

Use this property to enable or disable the use of the global chain validation cache. If enabled, the class will consult the product-wide validation cache when validating the signing chains. Also, the outcomes of any new chain validations performed by the class, both interim and final, will be saved in the cache and available for re-use by any future validations. Disable this property to ignore the cache and always perform the validation from a fresh start.

WidgetHeight: Specifies the height of the signature widget.
