The JAdESSigner module signs Javascript content electronically.

Syntax

SecureBlackbox.Jadessigner

Remarks

JAdESSigner supports a range of digital signature formats over Javascript content, including JSON Web Signatures (JWS) and ETSI JSON Advanced Electronic Signatures (JAdES).

Standards and technologies supported

JAdESSigner can create signatures that match the following standards:

• Generic JSON Web Signatures (JWS) (RFC7515)
• JAdES: all profiles are supported (BES, EPES, T, LTV, B-B, B-T, and others) (ETSI TS 119 182-1)
• Timestamps using external TSAs.
• All industry-standard cryptographic algorithms (RSA, ECDSA, SHA256-512, and many others).

Configuring the signature spec

JWS and JAdES signatures can come in all sorts of flavours, with the primary factors being the signature format (how exactly the signed data is represented in bytes) and completeness (the extent of the trust information that is included in the signature). You can use the properties of your JAdESSigner object to configure these and other parameters. Typically, the service or software that you need to communicate with will provide you with a list of requirements that your JSON signature needs to satisfy. In some cases, they will also send you an example signature that you may use as a guide.

Typically, you will need to adjust the following categories of settings:

• Level (plain JWS, B, T, LT, or LTA). This can be adjusted with the property.
• Timestamp requirement: provide the address of your online TSA service via TimestampServer property.
• When creating LT/LTA signatures, tune up validation parameters via RevocationCheck, OfflineMode, and IgnoreChainValidationErrors properties.
• Configure the signature representation parameters such as CompactForm, Detached or FlattenedSignature.

The above are the most important settings from each category; you may need to adjust more specific settings, such as EPES policy parameters (such as ) or ContentType, to fine-tune your signature.

Signing certificates

JAdESSigner 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), system stores/keychains, 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 or less interoperable media can be communicated with the external signing feature (see below).

Use CertificateManager and CertificateStorage components to load the signing certificate. Assign the certificate to SigningCertificate property, and optionally provide the remainder of its chain via the SigningChain property.

In the default configuration, JAdESSigner will do its best to collect the trust elements (certificates, CRLs, OCSP responses) required by the chosen signature level automatically. It will use all available sources, including the system stores, the chain validation cache, and the signature itself (when upgrading an existing signature). However, there can be situations where only some (or even none) of the trust elements are available in the public locations. This is particularly the case for internal, experimental, or test PKI environments. In such cases you might need to locate the missing elements manually and provide them to JAdESSigner via the KnownCertificates, KnownCRLs, and KnownOCSPs properties. You can also provide any trust anchors not included in the public Trusted Root directory via the TrustedCertificates collection.

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 component 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.

Signing the JSON

Now that you have configured the signature and certificate settings, you can proceed to signing. You can provide the JSON input in one of the following forms: as a file (assign the path to InputFile property), as a stream (assign to InputStream property), as a string (InputString), or as a byte array (assign to InputBytes). Similarly, the output can be collected in one of the same forms, either by passing the destination path or stream via OutputFile and OutputStream respectively, or by reading the resulting document bytes from the OutputBytes or OutputString property after the signing.

Having set up the input and output, call the component'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. when creating a B-level signature), or it may involve advanced chain validation routines (LT or LTA). During the latter the component contacts a number of external trust information sources (CA, CRL, and OCSP servers) to establish the validity of the signing certificate.

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

During the signing JAdESSigner may fire events to let your code know of certain conditions. It may fire TLSCertValidate 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 chain to be validated.

External signing and DCAuth

JAdESSigner, like many other components included in 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 scenario best.

Synchronous method: ExternalSign

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

To initiate this method, call SignExternal instead of Sign. When the hash is ready, it will be passed back to your code with ExternalSign event. Your event handler needs to sign the hash with the private key and return the created signature back to the component - 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 included in the hash calculation.

This method is synchronous, meaning SignExternal 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 JAdESSigner - initiates the operation using SignAsyncBegin call. This produces two outcomes: a pre-signed content (a JSON body with a blank signature placeholder), and a request state (an object containing a hash that needs to be signed). At this point the JAdESSigner 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, 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 signing controls, and passes the response state, together with the pre-signed content, to the signer's SignAsyncEnd method. SignAsyncEnd extracts the signature from the response state and incorporates it into the pre-signed object, hereby completing the signature.

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.

• RevocationCheck 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.
• OfflineMode 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 KnownCertificates, TrustedCertificates, KnownCRLs, and KnownOCSPs collections to look for the missing validation material.
• IgnoreChainValidationErrors 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.
• KnownCertificates, KnownCRLs, and KnownOCSPs let you provide your own validation material. This may be useful when working in OfflineMode, where the signer has no access to the validation sources, or where the validation material has already been collected.
• TrustedCertificates lets you provide a list of trust anchors, either as a complement to the system's or as an alternative to it.
• BlockedCertificates 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, SocketSettings, and TLSSettings let you tune up the connectivity and TLS options in accordance with local preferences.
• TLSClientChain lets you provide the client certificate and its chain for TLS client authentication.
• Subscribe to TLSCertValidate 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:

• ChainValidationResult contains the primary result of the chain validation routine: valid, valid but untrusted, invalid, or undefined.
• ChainValidationDetails 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.
• ValidationLog contains the detailed chain validation log. The log can often be very helpful in nailing down various validation issues.

}

@property (nonatomic,readwrite,assign,getter=autoValidateSignatures,setter=setAutoValidateSignatures:) BOOL autoValidateSignatures;

- (BOOL)autoValidateSignatures;
- (void)setAutoValidateSignatures :(BOOL)newAutoValidateSignatures;

Default Value

False

Remarks

This setting is switched off by default to speed up JSON processing. Even if the JWS/JAdES signature is loaded with this property set to false, you can validate the signatures manually on a later stage using the Revalidate method.

BlockedCertificates Property (JAdESSigner Module)

The certificates that must be rejected as trust anchors.

Syntax

• Swift

- (int)blockedCertCount;
- (void)setBlockedCertCount :(int)newBlockedCertCount;

- (NSData*)blockedCertBytes:(int)blockedCertIndex;

- (long long)blockedCertHandle:(int)blockedCertIndex;
- (void)setBlockedCertHandle:(int)blockedCertIndex :(long long)newBlockedCertHandle;

Default Value

- (NSString*)certValidFrom:(int)certIndex;

- (NSString*)certValidTo:(int)certIndex;

Default Value

""

Remarks

Use this property to access all certificates included into the signature(s) by its creator.

CompactForm Property (JAdESSigner Module)

Specifies if the JWS compact serialization to be used.

Syntax

• Swift
• Objective-C

public var compactForm: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=compactForm,setter=setCompactForm:) BOOL compactForm;

- (BOOL)compactForm;
- (void)setCompactForm :(BOOL)newCompactForm;

Default Value

False

Remarks

When this property is set to "true" value, the JAdES component will use the JWS compact serialization format when saving a signature.

The JWS compact serialization format is a compact, Url safe representation of a JWS (JSON Web Signature) or JWE (JSON Web Encryption) object, used for transmitting security tokens.

The JWS compact serialization format supports only one signature without unprotected header (only JWS or JAdES BaselineB signature).

ContentType Property (JAdESSigner Module)

Specifies payload content type.

Syntax

• Swift
• Objective-C

public var contentType: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=contentType,setter=setContentType:) NSString* contentType;

- (NSString*)contentType;
- (void)setContentType :(NSString*)newContentType;

Default Value

""

Remarks

Use this property to indicate the content type of the JWS Payload.

This property provides a way for the application to disambiguate among different kinds of objects that might be present in the payload, but it is typically not used when the kind of object is already known. The value of this property is a string that conforms to the Internet Media Type (MIME) format, such as "text/plain" or "application/json".

It is optional to use this property and it is recommended to omit the "application/" prefix of the media type value when it is not needed. The recipient of the signed message should treat the value as if "application/" were prepended to it, unless it already contains a '/'.

CRLs Property (JAdESSigner Module)

A collection of certificate revocation lists embedded into the signature by the signer.

Syntax

• Swift
• Objective-C

public var crLs: Array<CRL> {
  get {...}
}

@property (nonatomic,readonly,assign,getter=CRLCount) int CRLCount;

- (int)CRLCount;

- (NSData*)CRLBytes:(int)cRLIndex;

- (long long)CRLHandle:(int)cRLIndex;

- (NSString*)CRLIssuer:(int)cRLIndex;

- (NSString*)CRLIssuerRDN:(int)cRLIndex;

- (NSString*)CRLLocation:(int)cRLIndex;

- (NSString*)CRLNextUpdate:(int)cRLIndex;

- (NSString*)CRLThisUpdate:(int)cRLIndex;

Default Value

""

Remarks

Use this property to access the CRLs embedded into the signature by the signer.

DataBytes Property (JAdESSigner Module)

Use this property to pass a payload or an object data to module in the byte array form.

Syntax

• Swift
• Objective-C

public var dataBytes: Data {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=dataBytes,setter=setDataBytes:) NSData* dataBytes;

- (NSData*)dataBytes;
- (void)setDataBytes :(NSData*)newDataBytes;

Remarks

Assign a byte array containing a JWS payload or an object data to be processed to this property.

DataFile Property (JAdESSigner Module)

A path to a file containing a payload or an object data.

Syntax

• Swift
• Objective-C

public var dataFile: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=dataFile,setter=setDataFile:) NSString* dataFile;

- (NSString*)dataFile;
- (void)setDataFile :(NSString*)newDataFile;

Default Value

""

Remarks

Use this property to provide a JWS payload or an object data to be processed.

DataString Property (JAdESSigner Module)

Use this property to pass a payload or an object data to module in the string form.

Syntax

• Swift
• Objective-C

public var dataString: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=dataString,setter=setDataString:) NSString* dataString;

- (NSString*)dataString;
- (void)setDataString :(NSString*)newDataString;

Default Value

""

Remarks

Assign a string containing a JWS payload or an object data to be processed to this property.

Detached Property (JAdESSigner Module)

Specifies whether a detached signature should be produced or verified.

Syntax

• Swift
• Objective-C

public var detached: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=detached,setter=setDetached:) BOOL detached;

- (BOOL)detached;
- (void)setDetached :(BOOL)newDetached;

Default Value

False

Remarks

Use this property to specify whether a detached signature should be produced or verified.

When this property is set to "true" value, the JWS payload will be detached from the signature and may either be a single detached object or the result of concatenating multiple detached data objects. In other words, the JWS payload and the signature are stored in separate objects.

If this property is set to "true" value, the user must provide the detached content via the DataFile or DataStream or DataBytes or DataString properties.

When Detached is set to "false" value, the JWS payload is included with the signature as a single object.

ExternalCrypto Property (JAdESSigner Module)

Provides access to external signing and DC parameters.

Syntax

• Swift
• Objective-C

public var externalCrypto: ExternalCrypto {
  get {...}
}

@property (nonatomic,readwrite,assign,getter=externalCryptoAsyncDocumentID,setter=setExternalCryptoAsyncDocumentID:) NSString* externalCryptoAsyncDocumentID;

- (NSString*)externalCryptoAsyncDocumentID;
- (void)setExternalCryptoAsyncDocumentID :(NSString*)newExternalCryptoAsyncDocumentID;

@property (nonatomic,readwrite,assign,getter=externalCryptoCustomParams,setter=setExternalCryptoCustomParams:) NSString* externalCryptoCustomParams;

- (NSString*)externalCryptoCustomParams;
- (void)setExternalCryptoCustomParams :(NSString*)newExternalCryptoCustomParams;

@property (nonatomic,readwrite,assign,getter=externalCryptoExternalHashCalculation,setter=setExternalCryptoExternalHashCalculation:) BOOL externalCryptoExternalHashCalculation;

- (BOOL)externalCryptoExternalHashCalculation;
- (void)setExternalCryptoExternalHashCalculation :(BOOL)newExternalCryptoExternalHashCalculation;

@property (nonatomic,readwrite,assign,getter=externalCryptoHashAlgorithm,setter=setExternalCryptoHashAlgorithm:) NSString* externalCryptoHashAlgorithm;

- (NSString*)externalCryptoHashAlgorithm;
- (void)setExternalCryptoHashAlgorithm :(NSString*)newExternalCryptoHashAlgorithm;

@property (nonatomic,readwrite,assign,getter=externalCryptoKeyID,setter=setExternalCryptoKeyID:) NSString* externalCryptoKeyID;

- (NSString*)externalCryptoKeyID;
- (void)setExternalCryptoKeyID :(NSString*)newExternalCryptoKeyID;

@property (nonatomic,readwrite,assign,getter=externalCryptoKeySecret,setter=setExternalCryptoKeySecret:) NSString* externalCryptoKeySecret;

- (NSString*)externalCryptoKeySecret;
- (void)setExternalCryptoKeySecret :(NSString*)newExternalCryptoKeySecret;

@property (nonatomic,readwrite,assign,getter=externalCryptoMethod,setter=setExternalCryptoMethod:) int externalCryptoMethod;

- (int)externalCryptoMethod;
- (void)setExternalCryptoMethod :(int)newExternalCryptoMethod;

@property (nonatomic,readwrite,assign,getter=externalCryptoMode,setter=setExternalCryptoMode:) int externalCryptoMode;

- (int)externalCryptoMode;
- (void)setExternalCryptoMode :(int)newExternalCryptoMode;

@property (nonatomic,readwrite,assign,getter=externalCryptoPublicKeyAlgorithm,setter=setExternalCryptoPublicKeyAlgorithm:) NSString* externalCryptoPublicKeyAlgorithm;

- (NSString*)externalCryptoPublicKeyAlgorithm;
- (void)setExternalCryptoPublicKeyAlgorithm :(NSString*)newExternalCryptoPublicKeyAlgorithm;

 

Default Value

""

Remarks

Use this property to tune-up remote cryptography settings. SecureBlackbox supports two independent types of external cryptography: synchronous (based on the ExternalSign event) and asynchronous (based on the DC protocol and the DCAuth signing component).

ExtractPayload Property (JAdESSigner Module)

Specifies whether a payload should be extracted.

Syntax

• Swift
• Objective-C

public var extractPayload: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=extractPayload,setter=setExtractPayload:) BOOL extractPayload;

- (BOOL)extractPayload;
- (void)setExtractPayload :(BOOL)newExtractPayload;

Default Value

False

Remarks

Use this property to specify whether a payload should be extracted when signature loaded. This applies only to non-detached signatures with a payload.

When this property is set to "true" value, the JWS payload will be extracted from the signature.

The user must provide the OutputFile or OutputStream properties with a filename or stream where to save the payload, if none is provided then payload is returned via OutputBytes or OutputString properties.

FIPSMode Property (JAdESSigner Module)

Reserved.

Syntax

• Swift
• Objective-C

public var fipsMode: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=FIPSMode,setter=setFIPSMode:) BOOL FIPSMode;

- (BOOL)FIPSMode;
- (void)setFIPSMode :(BOOL)newFIPSMode;

Default Value

False

Remarks

This property is reserved for future use.

FlattenedSignature Property (JAdESSigner Module)

Specifies if the flattened signature to be used.

Syntax

• Swift
• Objective-C

public var flattenedSignature: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=flattenedSignature,setter=setFlattenedSignature:) BOOL flattenedSignature;

- (BOOL)flattenedSignature;
- (void)setFlattenedSignature :(BOOL)newFlattenedSignature;

Default Value

True

Remarks

This property determines whether to use the flattened JWS JSON serialization format. This format is optimized for the single digital signature case and flattens the general JWS JSON serialization syntax by removing the "signatures" member and instead placing the "protected", "header", and "signature" members at the top-level JSON object (at the same level as the "payload" member).

When the FlattenedSignature property is set to "true" value, the signature will be represented using the flattened JWS JSON serialization format, but it is only applicable when there is a single signature involved.

When the property is set to "false" value, the signature will be represented using the general JWS JSON serialization format.

IgnoreChainValidationErrors Property (JAdESSigner Module)

Makes the module tolerant to chain validation errors.

Syntax

• Swift
• Objective-C

public var ignoreChainValidationErrors: Bool {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=ignoreChainValidationErrors,setter=setIgnoreChainValidationErrors:) BOOL ignoreChainValidationErrors;

- (BOOL)ignoreChainValidationErrors;
- (void)setIgnoreChainValidationErrors :(BOOL)newIgnoreChainValidationErrors;

Default Value

False

Remarks

If this property is set to True, any errors emerging during certificate chain validation will be ignored. This setting may be handy if the purpose of validation is the creation of an LTV signature, and the validation is performed in an environment that doesn't trust the signer's certificate chain.

InputBytes Property (JAdESSigner Module)

Use this property to pass the input to module in byte array form.

Syntax

• Swift
• Objective-C

public var inputBytes: Data {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=inputBytes,setter=setInputBytes:) NSData* inputBytes;

- (NSData*)inputBytes;
- (void)setInputBytes :(NSData*)newInputBytes;

Remarks

Assign a byte array containing the data to be processed to this property.

InputFile Property (JAdESSigner Module)

The file to be signed.

Syntax

• Swift
• Objective-C

public var inputFile: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=inputFile,setter=setInputFile:) NSString* inputFile;

- (NSString*)inputFile;
- (void)setInputFile :(NSString*)newInputFile;

Default Value

""

Remarks

Provide the path to the JSON to be signed.

InputString Property (JAdESSigner Module)

Use this property to pass the input to module in the string form.

Syntax

• Swift
• Objective-C

public var inputString: String {
  get {...}
  set {...}
}

@property (nonatomic,readwrite,assign,getter=inputString,setter=setInputString:) NSString* inputString;

- (NSString*)inputString;
- (void)setInputString :(NSString*)newInputString;

Default Value

""

Remarks

Assign a string containing the data to be processed to this property.

KnownCertificates Property (JAdESSigner Module)

Additional certificates for chain validation.

Syntax

• Swift
• Objective-C

public var knownCertificates: Array<Certificate> {
  get {...}
}

@property (nonatomic,readwrite,assign,getter=knownCertCount,setter=setKnownCertCount:) int knownCertCount;

- (int)knownCertCount;
- (void)setKnownCertCount :(int)newKnownCertCount;

- (NSData*)knownCertBytes:(int)knownCertIndex;

- (long long)knownCertHandle:(int)knownCertIndex;
- (void)setKnownCertHandle:(int)knownCertIndex :(long long)newKnownCertHandle;

Default Value

""

Remarks

Use this property to supply a list of additional certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when intermediary CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the class manually.

The purpose of the certificates to be added to this collection is roughly equivalent to that of the Intermediate Certification Authorities system store in Windows.

Do not add trust anchors or root certificates to this collection: add them to TrustedCertificates instead.

KnownCRLs Property (JAdESSigner Module)

Additional CRLs for chain validation.

Syntax

• Swift
• Objective-C

public var knownCRLs: Array<CRL> {
  get {...}
}

@property (nonatomic,readwrite,assign,getter=knownCRLCount,setter=setKnownCRLCount:) int knownCRLCount;

- (int)knownCRLCount;
- (void)setKnownCRLCount :(int)newKnownCRLCount;

- (NSData*)knownCRLBytes:(int)knownCRLIndex;

- (long long)knownCRLHandle:(int)knownCRLIndex;
- (void)setKnownCRLHandle:(int)knownCRLIndex :(long long)newKnownCRLHandle;

Default Value

""

Remarks

Use this property to supply additional CRLs that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated CRLs are stored separately from the signed message or document.

KnownOCSPs Property (JAdESSigner Module)

Additional OCSP responses for chain validation.

Syntax

• Swift
• Objective-C

public var knownOCSPs: Array<OCSPResponse> {
  get {...}
}

@property (nonatomic,readwrite,assign,getter=knownOCSPCount,setter=setKnownOCSPCount:) int knownOCSPCount;

- (int)knownOCSPCount;
- (void)setKnownOCSPCount :(int)newKnownOCSPCount;

- (NSData*)knownOCSPBytes:(int)knownOCSPIndex;

- (long long)knownOCSPHandle:(int)knownOCSPIndex;
- (void)setKnownOCSPHandle:(int)knownOCSPIndex :(long long)newKnownOCSPHandle;

Default Value

""

Remarks

Use this property to supply additional OCSP responses that might be needed for chain validation. This property may be helpful when a chain is validated in offline mode, and the associated OCSP responses are stored separately from the signed message or document.

NewSignature Property (JAdESSigner Module)

Provides access to new signature properties.

• Swift
• Objective-C

public var newSignature: JAdESSignature {
  get {...}
}

@property (nonatomic,readonly,assign,getter=newSigCertificateIndex) int newSigCertificateIndex;

}

@property (nonatomic,readwrite,assign,getter=revocationCheck,setter=setRevocationCheck:) int revocationCheck;

- (int)revocationCheck;
- (void)setRevocationCheck :(int)newRevocationCheck;

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.

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.

Remarks

Use this property to supply a list of trusted certificates that might be needed for chain validation. An example of a scenario where you might want to do that is when root CA certificates are absent from the standard system locations (or when there are no standard system locations), and therefore should be supplied to the component manually.

The purpose of this certificate collection is largely the same as that of the Windows Trusted Root Certification Authorities system store.

Use this property with extreme care as it directly affects chain verifiability; a wrong certificate added to the trusted list may result in bad chains being accepted, and forfeited signatures being recognized as genuine. Only add certificates that originate from the parties that you know and trust.

ValidationMoment Property (JAdESSigner Module)

The time point at which signature validity is to be established.

Syntax

• Swift

- (NSString*)validationMoment;
- (void)setValidationMoment :(NSString*)newValidationMoment;

Default Value

""

Remarks

Use this property to specify the moment in time at which signature validity should be established. The time is in UTC. Leave the setting empty to stick to the default moment (either the signature creation time or the current time).

The validity of the same signature may differ depending on the time point chosen due to temporal changes in chain validities, revocation statuses, and timestamp times.

AddSignedHTTPHeaderField Method (JAdESSigner Module)

Use this method to add HTTP header field.

Syntax

• Swift
• Objective-C

public func addSignedHTTPHeaderField(fieldName: String) throws -> Void

- (void)addSignedHTTPHeaderField:(NSString*)fieldName;

Remarks

This method allows you to add HTTP header field to the list of fields that will be signed. The method takes one parameter: the name of the header field.

This method changes the type of signed data to HttpHeaders mechanism and triggers the HTTPHeaderFieldNeeded event when the value of the HTTP header field is needed.

Use "(request target)" value as a field name to add request method and target URI into the list of fields that will be signed.

AddSignedObject Method (JAdESSigner Module)

Use this method to add an object.

Syntax

• Swift
• Objective-C

public func addSignedObject(uri: String, contentType: String) throws -> Void

- (void)addSignedObject:(NSString*)URI :(NSString*)contentType;

Remarks

This method allows you to add an object to the list of objects that will be signed. The signed object is identified by its URI.

This method changes the type of signed data to ObjectByURI mechanism and triggers the ObjectNeeded event when the data of the object is needed.

AddSignedObjectHash Method (JAdESSigner Module)

Use this method to add an object hash.

Syntax

• Swift
• Objective-C

public func addSignedObjectHash(uri: String, contentType: String, hashData: Data) throws -> Void

- (void)addSignedObjectHash:(NSString*)URI :(NSString*)contentType :(NSData*)hash;

Remarks

This method allows you to add an object hash to the list of objects that will be signed. The signed object is identified by its URI.

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.

SignAsyncBegin Method (JAdESSigner Module)

Initiates the asynchronous signing operation.

Syntax

• Swift
• Objective-C

public func signAsyncBegin() throws -> String

- (NSString*)signAsyncBegin;

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 OutputFile (or OutputStream). 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 InputFile (or InputStream), and call SignAsyncEnd 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 SigningCertificate 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 SignAsyncEnd 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 SignAsyncBegin 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 SignAsyncEnd method.

SignAsyncEnd Method (JAdESSigner Module)

Completes the asynchronous signing operation.

Syntax

• Swift
• Objective-C

public func signAsyncEnd(asyncReply: String) throws -> Void

- (void)signAsyncEnd:(NSString*)asyncReply;

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 SignAsyncBegin call to InputFile (or InputStream). The method will embed the signature into the pre-signed document, and save the complete signed document to OutputFile (or OutputStream).

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 SigningCertificate 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 (SignAsyncBegin) 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 SignAsyncBegin 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 SignAsyncEnd method.

- (void)onExternalSign:(NSString*)operationId :(NSString*)hashAlgorithm :(NSString*)pars :(NSString*)data :(NSString**)signedData;

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.
