C2PASigner Component

Properties   Methods   Events   Config Settings   Errors  

Creates a C2PA Manifest, signs it, and embeds it into an asset.

Syntax

nsoftware.IPWorksLLM.C2PASigner

Remarks

The C2PASigner component produces Content Credentials: a signed C2PA Manifest that records how an asset was produced, which tool produced it, and whether generative AI was involved. The manifest is embedded directly into the asset, so the provenance travels with the file.

Supported Formats

The component embeds the manifest into the asset itself, so each container format needs its own support. JPEG, PNG and PDF are supported.

The format is detected from the asset itself; there is nothing to configure. An asset in any other format is refused rather than written incorrectly.

For PDF, only documents using classic cross-reference tables can be signed. A document using cross-reference streams is refused, because appending a table-style update to it would produce a file that readers reject.

Signing an Asset

Set InputFile to the asset to be signed, OutputFile to the destination, and SigningCert to a certificate with an associated private key. Calling Sign builds the manifest, signs it, and writes the result.

C2PASigner signer = new C2PASigner(); signer.InputFile = "photo.jpg"; signer.OutputFile = "photo-signed.jpg"; signer.ClaimGenerator = "MyApp/1.0"; signer.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "signer.pfx", "password", "*"); signer.Sign();

The signing certificate must carry the C2PA claim signing extended key usage, and the manifest is signed with the algorithm named by SignatureAlgorithm. The permitted algorithms are ES256, ES384, ES512, PS256, PS384, PS512, and Ed25519; the C2PA specification permits no others.

Disclosing AI-Generated Content

The most common reason to sign an asset is to disclose how it was created. The AddAction method records a single action in the manifest. Marking an asset as generative AI output is one call.

signer.AddAction("c2pa.created", "http://cv.iptc.org/newscodes/digitalsourcetype/trainedAlgorithmicMedia", "MyApp/1.0"); signer.Sign();

The second parameter is the digital source type. The C2PA specification requires that a digital source type accompany the c2pa.created action for every asset; use http://c2pa.org/digitalsourcetype/empty when the asset began as a new file with no digital content.

Adding Other Assertions

Anything beyond the assertions the component computes for itself is added with AddAssertion, which appends a raw assertion payload under a given label. This keeps the API stable as the C2PA standard assertion set evolves.

string creativeWork = "{\"@context\":\"https://schema.org\",\"@type\":\"CreativeWork\",\"author\":[{\"@type\":\"Person\",\"name\":\"Jane Doe\"}]}"; signer.AddAssertion("stds.schema-org.CreativeWork", "application/json", System.Text.Encoding.UTF8.GetBytes(creativeWork));

The content binding assertion, which cryptographically ties the manifest to the asset bytes, is always computed by the component and cannot be supplied by the application. Doing so is what makes tampering detectable.

Trusted Time-Stamps

Setting TSAURL to the address of an RFC 3161 Time Stamping Authority adds a trusted time-stamp to the signature. A time-stamped signature remains verifiable after the signing certificate expires, which is why the C2PA specification recommends obtaining one whenever a TSA can be reached.

signer.TSAURL = "http://timestamp.example.com/tsa"; signer.Sign();

Config Settings

The following is a list of config settings for the component with short descriptions. Click on the links for further details.

Actions Property (C2PASigner Component)

The actions recorded in the Manifest.

Syntax

• C#
• VB.NET

public C2PAActionList Actions { get; }
                

Public Property Actions As C2PAActionList
                

Remarks

Each entry describes something that was done to the content. AddAction is the short way to add one; this collection is how an application reads them back, and how it reaches the When field, which AddAction does not take.

The actions travel in a single c2pa.actions.v2 assertion, written when the Manifest is signed.

Example. Recording when an edit happened:

C2PASigner signer = new C2PASigner(); signer.InputFile = "edited.jpg"; signer.SigningCert = cert; signer.AddAction("c2pa.edited", "", "Acme Editor/3.0"); // AddAction takes no timestamp, so set it on the queued action. signer.Actions[0].When = "2026-09-01T10:30:00Z"; signer.Sign();

Example. Checking what will be recorded before signing:

for (int i = 0; i < signer.Actions.Count; i++) { Console.WriteLine(signer.Actions[i].Action + " by " + signer.Actions[i].SoftwareAgent); }

This property is not available at design time.

Assertions Property (C2PASigner Component)

The assertions to record in the C2PA Manifest.

Syntax

• C#
• VB.NET

public C2PAAssertionList Assertions { get; }
                

Public Property Assertions As C2PAAssertionList
                

Remarks

This collection holds the C2PAAssertion items written into the manifest when Sign is called. The AddAssertion and AddAction methods are a convenient way to append items without constructing them directly.

The content binding assertion, which ties the manifest to the asset bytes, is always computed by the component and is not part of this collection. An application cannot supply it, because a self-supplied binding would defeat tamper detection.

This property is not available at design time.

ClaimGenerator Property (C2PASigner Component)

The identifier of the tool that created the claim.

Syntax

• C#
• VB.NET

public string ClaimGenerator { get; set; }
                

Public Property ClaimGenerator As String
                

Default Value

""

Remarks

This property identifies the application that produced the C2PA Manifest, and is recorded in the claim so a consumer can see which tool made the provenance assertion.

Use a name and version, for example MyApp/1.0. When this property is left empty, the component records its own name and version.

This property is not available at design time.

Ingredients Property (C2PASigner Component)

The ingredients recorded in the Manifest.

Syntax

• C#
• VB.NET

public C2PAIngredientList Ingredients { get; }
                

Public Property Ingredients As C2PAIngredientList
                

Remarks

Each entry is an asset that went into the one being signed, added by AddIngredient. This collection is how an application reads them back before signing.

When an ingredient's source carried a Manifest of its own, ManifestLabel names it and that Manifest is carried in the store being written. When it did not, ManifestLabel is empty: the ingredient records what the source was, and the chain stops there.

Example. Reading back what was recorded:

signer.AddIngredient("original.jpg", "Original photograph", "parentOf"); C2PAIngredient added = signer.Ingredients[0]; Console.WriteLine(added.Title + " (" + added.Format + ") " + added.Relationship); if (added.ManifestLabel.Length > 0) { Console.WriteLine(" its own manifest travels along: " + added.ManifestLabel); } else { Console.WriteLine(" the source carried no manifest; the chain stops here"); }

This property is not available at design time.

InputData Property (C2PASigner Component)

The asset to process, held in memory.

Syntax

• C#
• VB.NET

public string InputData { get; set; }
public byte[] InputDataB { get; set; }
                

Public Property InputData As String
Public Property InputDataB As Byte()
                

Default Value

""

Remarks

This property specifies the asset to be processed as a byte array, for applications that do not work with files on disk.

When both InputFile and this property are set, InputFile takes precedence.

InputFile Property (C2PASigner Component)

The asset to process.

Syntax

• C#
• VB.NET

public string InputFile { get; set; }
                

Public Property InputFile As String
                

Default Value

""

Remarks

This property specifies the asset to be processed. Set it to the full or relative path of the file.

When both this property and InputData are set, this property takes precedence.

OutputData Property (C2PASigner Component)

The signed asset, held in memory.

Syntax

• C#
• VB.NET

public string OutputData { get; }
public byte[] OutputDataB { get; }
                

Public ReadOnly Property OutputData As String
Public ReadOnly Property OutputDataB As Byte()
                

Default Value

""

Remarks

This property holds the signed asset after the operation completes, when OutputFile was left empty.

This property is read-only.

OutputFile Property (C2PASigner Component)

The file to write the signed asset to.

Syntax

• C#
• VB.NET

public string OutputFile { get; set; }
                

Public Property OutputFile As String
                

Default Value

""

Remarks

This property specifies where the signed asset is written. Set it to the full or relative path of the destination file.

If this property is empty, the signed asset is written to OutputData instead.

An error is thrown if the file already exists and Overwrite is False.

Overwrite Property (C2PASigner Component)

Whether the component may overwrite an existing output file.

Syntax

• C#
• VB.NET

public bool Overwrite { get; set; }
                

Public Property Overwrite As Boolean
                

Default Value

False

Remarks

This property indicates whether the component will overwrite OutputFile. When it is False, an error is thrown if OutputFile already exists.

The default value is False.

SignatureAlgorithm Property (C2PASigner Component)

The algorithm used to sign the claim.

Syntax

• C#
• VB.NET

public string SignatureAlgorithm { get; set; }
                

Public Property SignatureAlgorithm As String
                

Default Value

"ES256"

Remarks

This property specifies the signature algorithm. The C2PA specification permits only the following values, and no others:

The value must be compatible with the key in SigningCert. The default value is ES256.

This property is not available at design time.

SigningCert Property (C2PASigner Component)

The certificate used to sign the C2PA Manifest.

Syntax

• C#
• VB.NET

public Certificate SigningCert { get; set; }
                

Public Property SigningCert As Certificate
                

Remarks

This property specifies the certificate used to sign the claim. The certificate must have an associated private key.

The C2PA specification requires that a claim signing certificate carry the c2pa-kp-claimSigning extended key usage, OID 1.3.6.1.4.1.62558.2.1. A certificate without it will be rejected by conforming validators even though the signature itself is well formed.

The full chain presented with the certificate is embedded in the signature, so a validator can build a path to its own trust anchors without fetching intermediates.

This property is not available at design time.

TSAURL Property (C2PASigner Component)

The address of an RFC 3161 Time Stamping Authority.

Syntax

• C#
• VB.NET

public string TSAURL { get; set; }
                

Public Property TSAURL As String
                

Default Value

""

Remarks

This property specifies the Time Stamping Authority contacted during signing. When it is set, the component obtains a trusted time-stamp over the signature and embeds it in the C2PA Manifest as a countersignature.

A time-stamped signature stays verifiable after the signing certificate expires, because a validator can establish that the signature existed while the certificate was still valid. The C2PA specification recommends obtaining a time-stamp whenever a TSA can be reached at signing time.

When this property is empty, no time-stamp is requested.

When it is set and the authority cannot be reached, or returns no token, signing fails rather than producing an untimestamped Manifest. Asking for a time-stamp and quietly getting none would leave a signature that looks complete but loses its meaning the day the certificate expires.

The connection to the authority is authenticated like any other: a TSA presenting an untrusted or expired certificate is refused. There is no event for overriding that decision.

This property is not available at design time.

AddAction Method (C2PASigner Component)

Records an action in the C2PA Manifest.

Syntax

• C#
• VB.NET

public void AddAction(string action, string digitalSourceType, string softwareAgent);

Async Version
public async Task AddAction(string action, string digitalSourceType, string softwareAgent);
public async Task AddAction(string action, string digitalSourceType, string softwareAgent, CancellationToken cancellationToken);
                

Public Sub AddAction(ByVal Action As String, ByVal DigitalSourceType As String, ByVal SoftwareAgent As String)

Async Version
Public Sub AddAction(ByVal Action As String, ByVal DigitalSourceType As String, ByVal SoftwareAgent As String) As Task
Public Sub AddAction(ByVal Action As String, ByVal DigitalSourceType As String, ByVal SoftwareAgent As String, cancellationToken As CancellationToken) As Task
                

Remarks

This method appends an action to the manifest's actions assertion, creating that assertion if it does not exist yet.

Action is the C2PA action identifier, such as c2pa.created, c2pa.edited, c2pa.opened, or c2pa.placed.

DigitalSourceType describes the nature of the content the action produced. The C2PA specification requires that a digital source type accompany the c2pa.created action for every asset. Commonly used values are:

Other values defined by the IPTC digital source type vocabulary may also be used. Pass an empty string when the action does not take one; a c2pa.opened action, for example, requires none.

SoftwareAgent names the tool that performed the action.

Disclosing AI-generated content is a single call:

signer.AddAction("c2pa.created", "http://cv.iptc.org/newscodes/digitalsourcetype/trainedAlgorithmicMedia", "MyApp/1.0");

AddAssertion Method (C2PASigner Component)

Appends an assertion to the Assertions collection.

Syntax

• C#
• VB.NET

public void AddAssertion(string assertionLabel, string mediaType, byte[] data);

Async Version
public async Task AddAssertion(string assertionLabel, string mediaType, byte[] data);
public async Task AddAssertion(string assertionLabel, string mediaType, byte[] data, CancellationToken cancellationToken);
                

Public Sub AddAssertion(ByVal AssertionLabel As String, ByVal MediaType As String, ByVal Data As Byte())

Async Version
Public Sub AddAssertion(ByVal AssertionLabel As String, ByVal MediaType As String, ByVal Data As Byte()) As Task
Public Sub AddAssertion(ByVal AssertionLabel As String, ByVal MediaType As String, ByVal Data As Byte(), cancellationToken As CancellationToken) As Task
                

Remarks

This method appends a new C2PAAssertion item to the Assertions collection.

AssertionLabel is the C2PA assertion label, such as stds.schema-org.CreativeWork or stds.exif. MediaType is the payload's media type, normally application/json or application/cbor. Data is the assertion payload.

Passing the payload through verbatim keeps the API stable as the C2PA standard assertion set evolves: a new assertion type can be written without waiting for a new build of the component.

string creativeWork = "{\"@context\":\"https://schema.org\",\"@type\":\"CreativeWork\",\"author\":[{\"@type\":\"Person\",\"name\":\"Jane Doe\"}]}"; signer.AddAssertion("stds.schema-org.CreativeWork", "application/json", System.Text.Encoding.UTF8.GetBytes(creativeWork));

Use AddAction instead when recording an action, since it builds the correctly structured actions assertion for you.

AddIngredient Method (C2PASigner Component)

Records that an asset went into the one being signed.

Syntax

• C#
• VB.NET

public void AddIngredient(string sourceFile, string title, string relationship);

Async Version
public async Task AddIngredient(string sourceFile, string title, string relationship);
public async Task AddIngredient(string sourceFile, string title, string relationship, CancellationToken cancellationToken);
                

Public Sub AddIngredient(ByVal SourceFile As String, ByVal Title As String, ByVal Relationship As String)

Async Version
Public Sub AddIngredient(ByVal SourceFile As String, ByVal Title As String, ByVal Relationship As String) As Task
Public Sub AddIngredient(ByVal SourceFile As String, ByVal Title As String, ByVal Relationship As String, cancellationToken As CancellationToken) As Task
                

Remarks

An ingredient is a source asset and the relationship it has to this one. Recording ingredients is what turns individual Manifests into a provenance chain: a consumer can follow an edited image back to the photograph it came from, and that one back to the camera that produced it.

SourceFile is the asset that went in. Title is a human-readable name for it; pass an empty string to omit it. Relationship is one of:

When the source carries a C2PA Manifest of its own, that Manifest is copied into the Manifest being written and the ingredient points at it. The chain then travels with the file: a verifier can follow it without needing the original source asset.

When the source carries no Manifest, the ingredient still records what the source was. The chain stops there, which is the truth about that asset rather than something to conceal.

Call this before Sign. Ingredients are read back through the Ingredients collection.

Example. Recording that an edited image came from a signed original:

C2PASigner signer = new C2PASigner(); signer.InputFile = "edited.jpg"; signer.OutputFile = "edited-signed.jpg"; signer.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "signer.pfx", "password", "*"); signer.ClaimGenerator = "Acme Editor/3.0"; // The photograph this edit was made from. Its Manifest travels along. signer.AddIngredient("original.jpg", "Original photograph", "parentOf"); signer.AddAction("c2pa.edited", "", "Acme Editor/3.0"); signer.Sign();

Example. Recording the sources of a generated image:

C2PASigner signer = new C2PASigner(); signer.InputFile = "generated.png"; signer.OutputFile = "generated-signed.png"; signer.SigningCert = cert; signer.ClaimGenerator = "Acme Generator/1.0"; signer.AddIngredient("reference.jpg", "Reference image", "inputTo"); // Disclose that the output is generative. signer.AddAction("c2pa.created", "http://cv.iptc.org/newscodes/digitalsourcetype/trainedAlgorithmicMedia", "Acme Generator/1.0"); signer.Sign();

Config Method (C2PASigner Component)

Sets or retrieves a configuration setting.

Syntax

• C#
• VB.NET

public string Config(string configurationString);

Async Version
public async Task<string> Config(string configurationString);
public async Task<string> Config(string configurationString, CancellationToken cancellationToken);
                

Public Function Config(ByVal ConfigurationString As String) As String

Async Version
Public Function Config(ByVal ConfigurationString As String) As Task(Of String)
Public Function Config(ByVal ConfigurationString As String, cancellationToken As CancellationToken) As Task(Of String)
                

Remarks

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

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, 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.

Reset Method (C2PASigner Component)

This method will reset the component.

Syntax

• C#
• VB.NET

public void Reset();

Async Version
public async Task Reset();
public async Task Reset(CancellationToken cancellationToken);
                

Public Sub Reset()

Async Version
Public Sub Reset() As Task
Public Sub Reset(cancellationToken As CancellationToken) As Task
                

Remarks

This method will reset the component's properties to their default values.

Sign Method (C2PASigner Component)

Builds, signs, and embeds a C2PA Manifest.

Syntax

• C#
• VB.NET

public void Sign();

Async Version
public async Task Sign();
public async Task Sign(CancellationToken cancellationToken);
                

Public Sub Sign()

Async Version
Public Sub Sign() As Task
Public Sub Sign(cancellationToken As CancellationToken) As Task
                

Remarks

This method reads the asset named by InputFile (or held in InputData), builds a C2PA Manifest from the Assertions collection, signs the claim with SigningCert, embeds the manifest into the asset, and writes the result to OutputFile (or OutputData).

The following example signs a JPEG and discloses that it was produced by a generative model.

C2PASigner signer = new C2PASigner(); signer.InputFile = "photo.jpg"; signer.OutputFile = "photo-signed.jpg"; signer.ClaimGenerator = "MyApp/1.0"; signer.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, "signer.pfx", "password", "*"); signer.AddAction("c2pa.created", "http://cv.iptc.org/newscodes/digitalsourcetype/trainedAlgorithmicMedia", "MyApp/1.0"); signer.Sign();

Signing is a two-pass operation. The manifest is embedded once at a reserved size so the final byte layout of the asset is known, the content binding hash is then computed over the asset outside the manifest's own bytes, and the real signature replaces the reservation. This is what allows the hash to cover an asset that contains the manifest.

An error is thrown when SigningCert has no private key, when SignatureAlgorithm is incompatible with that key, or when the input asset is of a format the component cannot embed into.

Error Event (C2PASigner Component)

Fired when information is available about errors during data delivery.

Syntax

• C#
• VB.NET

public event OnErrorHandler OnError;

public delegate void OnErrorHandler(object sender, C2PASignerErrorEventArgs e);

public class C2PASignerErrorEventArgs : EventArgs {
  public int ErrorCode { get; }
  public string Description { get; }
}

Async Version
public event AsyncEventHandler<C2PASignerErrorEventArgs> OnError;

public delegate Task AsyncEventHandler<TEventArgs>(object sender, TEventArgs e);

public class C2PASignerErrorEventArgs : AsyncEventArgs {
  public CancellationToken CancellationToken { get; }
  public int ErrorCode { get; }
  public string Description { get; }
}
                

Public Event OnError As OnErrorHandler

Public Delegate Sub OnErrorHandler(sender As Object, e As C2PASignerErrorEventArgs)

Public Class C2PASignerErrorEventArgs Inherits EventArgs
  Public ReadOnly Property ErrorCode As Integer
  Public ReadOnly Property Description As String
End Class

Async Version
Public Event OnError As AsyncEventHandler(Of C2PASignerErrorEventArgs)

Public Delegate Function AsyncEventHandler(Of TEventArgs)(sender As Object, e As TEventArgs) As Task

Public Class C2PASignerErrorEventArgs Inherits AsyncEventArgs
  Public ReadOnly Property CancellationToken As CancellationToken
  Public ReadOnly Property ErrorCode As Integer
  Public ReadOnly Property Description As String
End Class
                

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the component throws an exception.

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

Log Event (C2PASigner Component)

This event fires once for each log message.

Syntax

• C#
• VB.NET

public event OnLogHandler OnLog;

public delegate void OnLogHandler(object sender, C2PASignerLogEventArgs e);

public class C2PASignerLogEventArgs : EventArgs {
  public int LogLevel { get; }
  public string Message { get; }
  public string LogType { get; }
}

Async Version
public event AsyncEventHandler<C2PASignerLogEventArgs> OnLog;

public delegate Task AsyncEventHandler<TEventArgs>(object sender, TEventArgs e);

public class C2PASignerLogEventArgs : AsyncEventArgs {
  public CancellationToken CancellationToken { get; }
  public int LogLevel { get; }
  public string Message { get; }
  public string LogType { get; }
}
                

Public Event OnLog As OnLogHandler

Public Delegate Sub OnLogHandler(sender As Object, e As C2PASignerLogEventArgs)

Public Class C2PASignerLogEventArgs Inherits EventArgs
  Public ReadOnly Property LogLevel As Integer
  Public ReadOnly Property Message As String
  Public ReadOnly Property LogType As String
End Class

Async Version
Public Event OnLog As AsyncEventHandler(Of C2PASignerLogEventArgs)

Public Delegate Function AsyncEventHandler(Of TEventArgs)(sender As Object, e As TEventArgs) As Task

Public Class C2PASignerLogEventArgs Inherits AsyncEventArgs
  Public ReadOnly Property CancellationToken As CancellationToken
  Public ReadOnly Property LogLevel As Integer
  Public ReadOnly Property Message As String
  Public ReadOnly Property LogType As String
End Class
                

Remarks

This event fires once for each log message generated by the component. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

Message is the log entry.

LogType identifies the type of log entry. Possible values are Info, Manifest, Signature, and Validation.

C2PAAction Type

A single action recorded in the actions assertion.

Remarks

This type represents one entry in a C2PA Manifest's actions assertion: something that was done to the asset, by what, and what kind of content resulted.

The actions assertion is where an asset's history is written down, and it is the mechanism regulators point to for AI disclosure. An asset produced by a generative model carries a c2pa.created action whose DigitalSourceType identifies the output as trained algorithmic media.

• Action
• DigitalSourceType
• SoftwareAgent
• When

Fields

Constructors

• C#
• VB.NET

public C2PAAction();
                

Public C2PAAction()
                

C2PAAssertion Type

A single assertion recorded in a C2PA Manifest.

Remarks

This type represents one assertion: a labelled statement about the asset, stored in the manifest and covered by the claim signature.

Assertions are how a C2PA Manifest says anything at all. Some describe what was done to the asset, some describe who made it, and one, the content binding, ties the manifest to the asset bytes. Each carries a label defined by the C2PA specification and a payload whose shape that label determines.

The payload is exposed as raw data rather than parsed into typed fields, so that assertion types added to the standard after this component was built can still be read and written.

• AssertionLabel
• Data
• MediaType

• C#
• VB.NET

Public C2PAAssertion()
                

C2PAIngredient Type

An asset that went into the one being described.

Remarks

This type represents an ingredient: another asset that was used to produce this one, together with the relationship between them.

Ingredients are what turn individual manifests into a provenance chain. When an editor opens a photograph and places it into a composite, the composite's manifest records the photograph as an ingredient, carrying that photograph's own manifest with it. A consumer can then walk backwards through the chain to the original capture.

• Format
• InstanceId
• ManifestLabel
