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.

external_crypto_key_id Property
The ID of the pre-shared key used for DC request authentication.
Syntax
def get_external_crypto_key_id() -> str: ... def set_external_crypto_key_id(value: str) -> None: ...

Default Value
""
Remarks
The ID of the pre-shared key used for DC request authentication.
Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use external_crypto_key_secret to pass the key itself.
The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.
Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.
Example:
signer.ExternalCrypto.KeyID = "MainSigningKey";
signer.ExternalCrypto.KeySecret = "abcdef0123456789";
external_crypto_key_secret Property

Syntax
def get_revocation_check() -> int: ... def set_revocation_check(value: int) -> None: ...

Default Value
1
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 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |
This setting controls the way the revocation checks are performed for every certificate in the chain. 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.
Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.
Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

Default Value
1
Remarks
Specifies the kind(s) of revocation check to perform.
Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.
| crcNone | 0 | No revocation checking. |
| crcAuto | 1 | Automatic mode selection. Currently this maps to crcAnyOCSPOrCRL, but it may change in the future. |
| crcAllCRL | 2 | All provided CRL endpoints will be checked, and all checks must succeed. |
| crcAllOCSP | 3 | All provided OCSP endpoints will be checked, and all checks must succeed. |
| crcAllCRLAndOCSP | 4 | All provided CRL and OCSP endpoints will be checked, and all checks must succeed. |
| crcAnyCRL | 5 | All provided CRL endpoints will be checked, and at least one check must succeed. |
| crcAnyOCSP | 6 | All provided OCSP endpoints will be checked, and at least one check must succeed. |
| crcAnyCRLOrOCSP | 7 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. CRL endpoints are checked first. |
| crcAnyOCSPOrCRL | 8 | All provided CRL and OCSP endpoints will be checked, and at least one check must succeed. OCSP endpoints are checked first. |
This setting controls the way the revocation checks are performed for every certificate in the chain. 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.
Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.
Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

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.

def get_widget_rotate() -> int: ... def set_widget_rotate(value: int) -> None: ...
widget_rotate = property(get_widget_rotate, set_widget_rotate)
Default Value
0
Remarks
Specifies the rotation angle of the signature widget in degrees. Values of 0, 90, 180, and 270 are allowed.
widget_show_date Property
Whether to display the signing date and time details on the widget.
Syntax
def get_widget_show_date() -> bool: ... def set_widget_show_date(value: bool) -> None: ...
widget_show_date = property(get_widget_show_date, set_widget_show_date)
Default Value
TRUE
Remarks
Whether to display the signing date and time details on the widget.
widget_show_visual_status Property
Specifies whether to show the signature's status icon.
Syntax
def get_widget_show_visual_status() -> bool: ... def set_widget_show_visual_status(value: bool) -> None: ...
widget_show_visual_status = property(get_widget_show_visual_status, set_widget_show_visual_status)
Default Value
FALSE
Remarks
Specifies whether to show the signature's status icon.
It is a good idea to avoid using the visual status icon, as described below:
According to the Digital Signature Appearances Adobe Acrobat SDK (May 2015), "Prior to Acrobat 6.0, signature appearances were manipulated at run-time in order to display the validity of the signature. The validity was shown as a graphic icon and with an additional, optional text message. The manipulated portions of the signature appearance were contained in layers n1, n3 and n4. Beginning with version 6, Acrobat does not maintain support for signature appearances that can be manipulated, though legacy signatures with these appearances may continue to display correctly. Use of layers n1, n3, and n4 is not recommended."
widget_signer_caption Property
Specifies the caption for the signer section on the signature widget.
Syntax
def get_widget_signer_caption() -> str: ... def set_widget_signer_caption(value: str) -> None: ...
widget_signer_caption = property(get_widget_signer_caption, set_widget_signer_caption)
Default Value
"#auto"
Remarks
Specifies the caption for the signer section on the signature widget.
The default value, which is used if the property is set to #auto, is "Signer: ".
widget_signer_info Property
Provides custom signer information to put on the signature widget.
Syntax
def get_widget_signer_info() -> str: ... def set_widget_signer_info(value: str) -> None: ...
widget_signer_info = property(get_widget_signer_info, set_widget_signer_info)
Default Value
"#auto"
Remarks
Provides custom signer information to put on the signature widget.
The standard signature widget allows for several short strings separated by CRLF. Keep this property set to #auto to make the component generate the signer text automatically.
add_widget_custom_data Method

| "FontSizeX" | The horizontal font size of the text. | |
| "FontSizeY" | The vertical font size of the text. | |
| "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

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_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
Saves a PDF attachment to a file.
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.
revalidate Method
Revalidates a signature in accordance with current settings.
Syntax
def revalidate(index: int) -> None: ...
Remarks
Use this method to re-validate a signature in the opened PDF document.
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.
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.
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_index: int) -> 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 SigIndex to the index 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
Fires when there is a need to download a chain element from an online source.
Syntax
class PDFSignerChainElementDownloadEventParams(object): @property def kind() -> int: ... @property def cert_rdn() -> str: ... @property def ca_cert_rdn() -> str: ... @property def location() -> str: ... @property def action() -> int: ... @action.setter def action(value) -> None: ... # In class PDFSigner: @property def on_chain_element_download() -> Callable[[PDFSignerChainElementDownloadEventParams], None]: ... @on_chain_element_download.setter def on_chain_element_download(event_hook: Callable[[PDFSignerChainElementDownloadEventParams], None]) -> None: ...

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 |

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 issuer_rdn() -> str: ... @property def serial_number() -> bytes: ... @property def subject_key_id() -> bytes: ... @property def cert_found() -> bool: ... @property def validate_signature() -> bool: ... @validate_signature.setter def validate_signature(value) -> None: ... @property def validate_chain() -> bool: ... @validate_chain.setter def validate_chain(value) -> None: ... # 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.
Syntax
class PDFSignerSignatureValidatedEventParams(object): @property def index() -> int: ... @property def issuer_rdn() -> str: ... @property def serial_number() -> bytes: ... @property def subject_key_id() -> bytes: ... @property def validation_result() -> int: ... # In class PDFSigner: @property def on_signature_validated() -> Callable[[PDFSignerSignatureValidatedEventParams], None]: ... @on_signature_validated.setter def on_signature_validated(event_hook: Callable[[PDFSignerSignatureValidatedEventParams], None]) -> None: ...
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 |
on_timestamp_found Event
Signifies the start of a timestamp validation routine.
Syntax
class PDFSignerTimestampFoundEventParams(object): @property def index() -> int: ... @property def issuer_rdn() -> str: ... @property def serial_number() -> bytes: ... @property def subject_key_id() -> bytes: ... @property def cert_found() -> bool: ... @property def validate_timestamp() -> bool: ... @validate_timestamp.setter def validate_timestamp(value) -> None: ... @property def validate_chain() -> bool: ... @validate_chain.setter def validate_chain(value) -> None: ... # In class PDFSigner: @property 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.
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.
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: ... @timestamp_response.setter def timestamp_response(value) -> None: ... @property def suppress_default() -> bool: ... @suppress_default.setter def suppress_default(value) -> None: ... # In class PDFSigner: @property def on_timestamp_request() -> Callable[[PDFSignerTimestampRequestEventParams], None]: ... @on_timestamp_request.setter 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
Reports the completion of the timestamp validation routine.
Syntax
class PDFSignerTimestampValidatedEventParams(object): @property def index() -> int: ... @property def issuer_rdn() -> str: ... @property def serial_number() -> bytes: ... @property def subject_key_id() -> bytes: ... @property def time() -> str: ... @property def validation_result() -> int: ... @property def chain_validation_result() -> int: ... @property def chain_validation_details() -> int: ... # In class PDFSigner: @property def on_timestamp_validated() -> Callable[[PDFSignerTimestampValidatedEventParams], None]: ... @on_timestamp_validated.setter def on_timestamp_validated(event_hook: Callable[[PDFSignerTimestampValidatedEventParams], None]) -> None: ...
Remarks
This event is fired upon the completion of the timestamp validation routine, and reports the respective validation result.
ValidationResult is set to 0 if the validation has been successful, or to a non-zero value in case of a 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 |
on_tls_cert_needed Event
Fires when a remote TLS party requests a client certificate.
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. In order to avoid "polluting" the property namespace of the class, access to these internal properties is provided through the config method.PDFSigner Config Settings
Supported values are:
| GTS_PDFA1.sRGB | GTS_PDFA1 corresponding to the PDF/A standard as defined by ISO 19005. sRGB IEC61966-2.1 is a standard color space. | |
| GTS_PDFX.sRGB | GTS_PDFX corresponding to the PDF/X format standard specified in ISO 15930. sRGB IEC61966-2.1 is a standard color space. |
Output intents describe the final destination device you will use to reproduce the color in the PDF, such as the separations printing device. Output intents override working spaces during viewing and printing, but they do not convert the colors in the PDF.
Supported values are:
| AcrobatFriendlyAcroForm | Acrobat reader friendly form | |
| AdjustTimesToUTC | Asserts that all the time properties are set in local time and should be adjusted to UTC when writing to the document |
The default value is 0, which means that BitsPerComponent is set automatically according to the widget's property.
Supported values are:
For advanced settings of the build properties, use the BuildProperties configuration setting.
For advanced settings of the build properties, use the BuildProperties configuration setting.
Sample value:
{
"App":{
"Name":"TestApp",
"REx":"8.0.0"
}
}
The above value sets the application name and version used to create the signature. The same result could be achieved using the BuildApplicationName and BuildApplicationVersion configuration settings.
Sample value 2:
{
"App":{
"Name":"TestApp",
"REx":"8.0.0",
"R":524288,
"Date":"2023-01-01 00:01",
"OS":[
"Win"
],
"TrustedMode":true
},
"Filter":{
"Name":"TestFilter",
"R":131101,
"Date":"2023-01-01 00:02",
"PreRelease":true
},
"PubSec":{
"R":13102,
"Date":"2023-01-01 00:03",
"PreRelease":true,
"NonEFontNoWarn":true
}
}
Supported values are:
| none | No extensions | |
| ESIC | ESIC Extension Level 2 | |
| ADBE | Adobe Extension Level 8 | |
| ADBEIfNotPresent | Adobe Extension Level 8 if not present | |
| Both | Both (ESIC and Adobe) extensions |
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.
This setting is used by the on_notification event when the EventID parameter is "SignatureWidgetPrepare" to allow support for multi-widget signatures.
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. |
The following values are supported:
| "auto" | Default value. The class automatically reassembles PDF documents in case they contain errors that may invalidate new signatures. | |
| "disabled" | The class never reassembles PDF documents. This value is not recommended. | |
| "enabled" | The class always reassembles PDF documents. | |
| "hybrid" | The class reassembles PDF documents in the same cases as in "auto" mode and additionally reassembles hybrid PDF documents - documents that contain cross-reference tables and cross-reference streams. |
This setting is used to provide parameters for some cryptographic schemes. Use the Name1=Value1;Name2=Value2;... syntax to encode the parameters. For example: Scheme=PSS;SaltSize=32;TrailerField=1.
Supported values are:
| SuppressEmptyAuthorName | When this flag is not set, the author name in the signature is set to "Not specified". | |
| AddAnnotationForInvisibleSignature | When this flag is set, the annotation object is added for invisible signatures. |
- 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
In case of a timestamping failure, provide new TSA and HTTP settings inside the on_notification event handler ('BeforeTimestamp' and 'TimestampError' event IDs).
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.
This property extends the new_sig_height property to allow the height of the signature widget to be specified in fractional points.
This property extends the new_sig_offsetx property to allow the offset of the signature widget to be specified in fractional points.
This property extends the new_sig_offsety property to allow the offset of the signature widget to be specified in fractional points.
This property extends the new_sig_width property to allow the width of the signature widget to be specified in fractional points.
