Returns nil if the encryption feature is not enabled.

Declaration

Objective-C

- (nullable instancetype)
    initWithOutputStream:(nonnull NSOutputStream *)stream
         encryptionBlock:
             (nonnull NSData *_Nonnull (^)(PSPDFCryptoOutputStream *_Nonnull,
                                           const uint8_t *_Nonnull,
                                           NSUInteger))encryptionBlock;

Swift

init?(outputStream stream: OutputStream, encryptionBlock: @escaping (CryptoOutputStream, UnsafePointer<UInt8>, UInt) -> Data)


                      
                      
                      
                      
                      encryptionBlock

Set the encryption handler. If no encryption block is called, this output stream will simply pass the data through.

Note

Set this property before the output stream is being used.

Declaration

Objective-C

@property (nonatomic, copy) NSData *_Nonnull (^_Nonnull) (PSPDFCryptoOutputStream *_Nonnull, const uint8_t *_Nonnull, NSUInteger) encryptionBlock;

Swift

var encryptionBlock: (CryptoOutputStream, UnsafePointer<UInt8>, UInt) -> Data { get set }
