```
public PdfSignatureAppearance getSignatureAppearance()
```
    Provides access to a signature appearance object. Use it to customize the appearance of the signature.
    Be aware:
    - If you create new signature field (either use setFieldName(java.lang.String) with the name that doesn't exist in the document or don't specify it at all) then the signature is invisible by default.
    - If you sign already existing field, then the signature appearance object is modified to have all the properties (page num., rect etc.) consistent with the state of the field (if you customized the appearance object before the setFieldName(java.lang.String) call you'll have to do it again)
    Returns:
    
    PdfSignatureAppearance object.

    a collection of CRL bytes that can be embedded in a PDF
  - addDeveloperExtension
```
protected void addDeveloperExtension(PdfDeveloperExtension extension)
```
  - isPreClosed
```
protected boolean isPreClosed()
```
    Checks if the document is in the process of closing.
    
    Returns:
    
    true if the document is in the process of closing, false otherwise
  - preClose
```
protected void preClose(Map<PdfName,Integer> exclusionSizes)
                 throws IOException
```
    This is the first method to be called when using external signatures. The general sequence is: preClose(), getDocumentBytes() and close().
    exclusionSizes must contain at least the PdfName.CONTENTS key with the size that it will take in the document. Note that due to the hex string coding this size should be byte_size*2+2.
    
    Parameters:
    
    exclusionSizes - Map with names and sizes to be excluded in the signature calculation. The key is a PdfName and the value an Integer. At least the /Contents must be present
    
    Throws:
    
    IOException - on error
  - getRangeStream
```
protected InputStream getRangeStream()
                              throws IOException
```
    Gets the document bytes that are hashable when using external signatures. The general sequence is: preClose(Map), getRangeStream() and close(PdfDictionary).
    
    Returns:
    
    The InputStream of bytes to be signed.
    
    Throws:
    
    IOException
  - close
```
protected void close(PdfDictionary update)
              throws IOException
```
    This is the last method to be called when using external signatures. The general sequence is: preClose(), getDocumentBytes() and close().
    update is a PdfDictionary that must have exactly the same keys as the ones provided in preClose(Map).
    
    Parameters:
    
    update - a PdfDictionary with the key/value that will fill the holes defined in preClose(Map)
    
    Throws:
    
    IOException - on error
  - getUnderlyingSource
```
protected IRandomAccessSource getUnderlyingSource()
                                           throws IOException
```
    Returns the underlying source.
    
    Returns:
    
    The underlying source
    
    Throws:
    
    IOException
  - addDocMDP
```
protected void addDocMDP(PdfSignature crypto)
```
    Adds keys to the signature dictionary that define the certification level and the permissions. This method is only used for Certifying signatures.
    
    Parameters:
    
    crypto - the signature dictionary
  - addFieldMDP
```
protected void addFieldMDP(PdfSignature crypto,
                           PdfSigFieldLock fieldLock)
```
    Adds keys to the signature dictionary that define the field permissions. This method is only used for signatures that lock fields.
    
    Parameters:
    
    crypto - the signature dictionary
    
    fieldLock -
  - documentContainsCertificationOrApprovalSignatures
```
protected boolean documentContainsCertificationOrApprovalSignatures()
```
  - getWidgetRectangle
```
protected Rectangle getWidgetRectangle(PdfWidgetAnnotation widget)
```
    Get the rectangle associated to the provided widget.
    
    Parameters:
    
    widget - PdfWidgetAnnotation to extract the rectangle from
    
    Returns:
    
    Rectangle
  - getWidgetPageNumber
```
protected int getWidgetPageNumber(PdfWidgetAnnotation widget)
```
    Get the page number associated to the provided widget.
    
    Parameters:
    
    widget - PdfWidgetAnnotation from which to extract the page number
    
    Returns:
