The JAdESVerifier module verifies signatures over JSON objects.

Syntax

SecureBlackbox.Jadesverifier

Remarks

Use JAdESVerifier to validate electronic signatures over JSON structures. Generic (JWS) and JAdES (JSON Advanced Electronic Signatures) are supported.

JAdESVerifier validates each signature from two perspectives: the integrity and validity of the signature itself (i.e. its correspondence to the JSON data it covers), and the validity and trustworthiness of the signing certificate chain. These two signature aspects are generally independent of each other: the signature may be valid but the chain may not be trusted, or, the other way round, the chain may be trusted, but the integrity of the signature may be violated. Under normal circumstances both the signature and the chain must be valid for the signature to be considered good.

To initiate the validation, assign the path to the signed JSON file to the InputFile property (alternatively, you can provide it in a memory buffer via InputBytes or InputString property), and call Verify method. For every signature located in the document, JAdESVerifier will fire the SignatureFound event. This event lets you specify whether you want JAdESVerifier to validate the signature, the chain, or both.

Note: it does not mean that any of the two is optional. This API lets you be flexible in how you validate documents in your code, to allow for a variety of validation scenarios. For example, if your trust environment relies on certificate pinning, validating the chain by JAdESVerifier internally may cause unnecessary burden on the system, in which case (but not in others!) it may be reasonable to disable it in the event handler.

Once SignatureFound returns, JAdESVerifier proceeds to the signature validation routine in accordance with the provided settings. Upon completion of the validation, SignatureValidated event is fired, and the validation results are separately provided via SignatureValidationResult and ChainValidationResult properties of the relevant signature object. Other information about the signature can be accessed via the Signatures property.

Useful settings and properties

The following properties of JAdESVerifier may be handy when working with this component:

• OfflineMode lets you validate the JSON object without contacting online revocation sources. Paired with switched off system trust settings, it can be used to establish the long-term validity of the signed object and the completeness of validation material included in it.
• RevocationCheck lets you adjust the revocation checking preferences.
• ValidatedSigningTime returns the signing time as recorded in the embedded signature timestamp. This is in contrast to ClaimedSigningTime, which returns the signing time as specified by the signer.
• ValidationLog is a great way to find out the details of chain validation failures. This property returns a comprehensive validation log that reports all the issues encountered during the validation.

By default, JAdESVerifier uses the system trust settings to establish certificate chain validity. You can configure it to use your own, custom validation environment by providing the necessary trust elements via KnownCertificates, TrustedCertificates, KnownCRLs, and other similar properties.

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.

ExtractPayload Property (JAdESVerifier 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 (JAdESVerifier Module)

Reserved.

Syntax

• Swift
• Objective-C

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

• 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 (JAdESVerifier Module)

Makes the module tolerant to chain validation errors.

- (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 (JAdESVerifier Module)

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

Syntax

• Swift
• Objective-C

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

- (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 (JAdESVerifier Module)

Additional CRLs for chain validation.

Syntax

• Swift
• Objective-C

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

- (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 (JAdESVerifier Module)

Additional OCSP responses for chain validation.

Syntax

• Swift
• Objective-C

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

- (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.

OCSPs Property (JAdESVerifier Module)

A collection of OCSP responses embedded into the signature.

Syntax

• Swift
• Objective-C

public var ocsPs: Array<OCSPResponse> {

  set {...}
}

@property (nonatomic,readwrite,assign,getter=offlineMode,setter=setOfflineMode:) BOOL offlineMode;

- (BOOL)offlineMode;
- (void)setOfflineMode :(BOOL)newOfflineMode;

Default Value

False

Remarks

When working in offline mode, the class restricts itself from using any online revocation information sources, such as CRL or OCSP responders.

Offline mode may be useful if there is a need to verify the completeness of the validation information included within the signature or provided via KnownCertificates, KnownCRLs, and other related properties.

OutputBytes Property (JAdESVerifier Module)

Use this property to read the output the module object has produced.

Syntax

• Swift
• Objective-C

- (NSString*)profile;
- (void)setProfile :(NSString*)newProfile;

Default Value

""

Remarks

Advanced signatures come in many variants, which are often defined by parties that needs to process them or by local standards. SecureBlackbox profiles are sets of pre-defined configurations which correspond to particular signature variants. By specifying a profile, you are pre-configuring the component to make it produce the signature that matches the configuration corresponding to that profile.

RevocationCheck Property (JAdESVerifier Module)

Specifies the kind(s) of revocation check to perform for all chain certificates.

Syntax

• Swift
• Objective-C

public enum JadesverifierRevocationChecks: Int32 {
  case crcNone = 0
  case crcAuto = 1
  case crcAllCRL = 2
  case crcAllOCSP = 3
  case crcAllCRLAndOCSP = 4
  case crcAnyCRL = 5
  case crcAnyOCSP = 6
  case crcAnyCRLOrOCSP = 7
  case crcAnyOCSPOrCRL = 8
}

@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.

Signatures Property (JAdESVerifier Module)
