SignatureInformationAdapter

public SignatureInformationAdapter(SignatureHolder signatureHolder)

Constructor.

Parameters:

signatureHolder - The framework SignatureHolder to be adapted to an API SignatureInformation.

Method Detail

getSignedData

public DataSource getSignedData()

Description copied from interface: SignatureInformation

Returns the DataSource providing the data that was signed.

Note that this is the signed data as sent to the verification device by PDF-AS. The verification device (e.g. MOA) may perform several other transformations on the data before feeding it to the signature hash function. To get the actual hashed data use the ReturnHashInputData mechanism (which is very slow).

Specified by:

getSignedData in interface SignatureInformation

Returns:

Returns the DataSource providing the data that was signed.

See Also:

SignatureInformation.getSignedData()

getInternalSignatureInformation

public Object getInternalSignatureInformation()

Description copied from interface: SignatureInformation

Returns additional, internal information about the found signature.

Note that this provides a way for developers to gather core information about the signature. What information is returned strongly depends on the core implementation.

Specified by:

getInternalSignatureInformation in interface SignatureInformation

Returns:

Returns additional, internal information about the signature. Null means that no additional information is available.

See Also:

SignatureInformation.getInternalSignatureInformation()

getSignatureType

public String getSignatureType()

Description copied from interface: SignatureInformation

Returns the type of this signature (binary/textual).

May be Constants.SIGNATURE_TYPE_BINARY or Constants.SIGNATURE_TYPE_TEXTUAL.

Specified by:

getSignatureType in interface SignatureInformation

Returns:

Returns the type of this signature (binary/textual).

See Also:

SignatureInformation.getSignatureType()

getSignerCertificate

public X509Certificate getSignerCertificate()

Description copied from interface: SignatureInformation

Returns the certificate of the signer.

Information like subject name, issuer name or serial number can be retrieved form this certificate.

Specified by:

getSignerCertificate in interface SignatureInformation

Returns:

Returns the certificate of the signer.

See Also:

SignatureInformation.getSignerCertificate()

getSigningTime

public Date getSigningTime()

Description copied from interface: SignatureInformation

Returns the signing time, which is the time when the signature was created.

Specified by:

getSigningTime in interface SignatureInformation

Returns:

Returns the signing time, which is the time when the signature was created.

See Also:

SignatureInformation.getSigningTime()

getTimeStampValue

public String getTimeStampValue()

Description copied from interface: SignatureInformation

Returns the embedded /TimeStamp value (b64 encoded) from the signature if available.

Specified by:

getTimeStampValue in interface SignatureInformation

Returns:

getNonTextualObjects

public List getNonTextualObjects()

Description copied from interface: SignatureInformation

Returns a list<NonTextObjectInfo> of non textual objects in the pdf document. Only available for textual signatures. Show this to the user who signed the textual content only!

Specified by:

getNonTextualObjects in interface SignatureInformation

Returns:

List<NonTextObjectInfo or null of not available (binary signature)

hasNonTextualObjects

public boolean hasNonTextualObjects()

Description copied from interface: SignatureInformation

Returns true if non textual objects have been found, false if not.

Specified by:

hasNonTextualObjects in interface SignatureInformation

Returns:

true if non textual objects have been found, false if not.

setNonTextualObjects

public void setNonTextualObjects(List nonTextualObjects)

Specified by:

setNonTextualObjects in interface SignatureInformation
