ISO 32000-2:2017(E) Table 255 — Entries in a signature dictionary

  • Specifies how many placeholder bytes will be reserved for the signature.

    Declaration

    Objective-C

    @property (nonatomic, readonly) NSUInteger placeholderBytes;

    Swift

    var placeholderBytes: UInt { get }

  • The signature value as data.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSData *contents;

    Swift

    var contents: Data? { get }

  • The byte range of the data being signed. An array of pairs of integers (wrapped as NSNumber, starting byte offset, ending byte offset) that shall describe the exact byte range for the digest calculation. Multiple discontiguous byte ranges shall be used to describe a digest that does not include the signature value (the Contents entry) itself. If SubFilter is ETSI.CAdES.detached, the ByteRange shall cover the entire file, including the signature dictionary but excluding the Contents value.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSArray<NSNumber *> *byteRange;

  • The PDF filter name to use for this signer. Typical values are Adobe.PPKLite, Entrust.PPKEF, CICI.SignIt, and VeriSign.PPKVS. Returns Adobe.PPKLite as default value, as it’s the only value supported for now.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSString *filter;

    Swift

    var filter: String? { get }

  • The PDF SubFilter entry value. Tied to signatureType. Typical values are ETSI.CAdES.detached, adbe.pkcs7.detached, and adbe.pkcs7.sha1.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSString *subFilter;

    Swift

    var subFilter: String? { get }

  • The name.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSString *name;

    Swift

    var name: String? { get }

  • The creation date of the signature.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSDate *creationDate;

    Swift

    var creationDate: Date? { get }

  • The place where this signature was created. For example, ‘Vienna’.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSString *location;

    Swift

    var location: String? { get }

  • The reason that will be embedded in every digital signature created by this instance of PSPDFSigner. For example, if you are signing a PDF contract you can set this property to I agree with the terms of this contract.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSString *reason;

    Swift

    var reason: String? { get }

  • The build properties of the signature.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) PSPDFSignaturePropBuild *propBuild;

    Swift

    @NSCopying var propBuild: PSPDFSignaturePropBuild? { get }

  • (Optional; PDF 1.5) An array of signature reference dictionaries.

    Declaration

    Objective-C

    @property (nonatomic, copy, readonly, nullable) NSArray<PSPDFDigitalSignatureReference *> *references;

    Swift

    var references: [PSPDFDigitalSignatureReference]? { get }

  • The byte range of the data being signed. An array of ranges (starting byte offset, length in bytes) that shall describe the exact byte range for the digest calculation. Multiple discontiguous byte ranges shall be used to describe a digest that does not include the signature value (the Contents entry) itself. If SubFilter is ETSI.CAdES.detached, the ByteRange shall cover the entire file, including the signature dictionary but excluding the Contents value.

    Declaration

    Swift

    public var byteRange: [Range<UInt64>]? { get }
