} finally {
if (streamOut != null) streamOut.close();
}
} finally {
if (streamIn != null) streamIn.close();
}
Returns: java.lang.String - The corresponding java.lang.String value.
getDecryptionPassword()
public String getDecryptionPassword()
The password to decrypt source document. Default value is empty string.
Remarks:
If OOXML document is encrypted, you should provide decryption password to decrypt source document before it will be signed. This is not required for documents in binary DOC format.
Examples:
Shows how to sign encrypted document file.
// Create an X.509 certificate from a PKCS#12 store, which should contain a private key.
CertificateHolder certificateHolder = CertificateHolder.create(getMyDir() + "morzal.pfx", "aw");

Returns: java.lang.String - The corresponding java.lang.String value.
getProviderId()
public UUID getProviderId()
Specifies the class ID of the signature provider. Default value is Empty (all zeroes) Guid.
Remarks:
The cryptographic service provider (CSP) is an independent software module that actually performs cryptography algorithms for authentication, encoding, and encryption. MS Office reserves the value of {00000000-0000-0000-0000-000000000000} for its default signature provider.
The GUID of the additionally installed provider should be obtained from the documentation shipped with the provider.
In addition, all the installed cryptographic providers are enumerated in windows registry. It can be found in the following path: HKLM\SOFTWARE\Microsoft\Cryptography\Defaults\Provider. There is a key name “CP Service UUID” which corresponds to a GUID of signature provider.

getArtifactsDir() + "DocumentBuilder.SignatureLineProviderId.Signed.docx", certHolder, signOptions);
// Re-open our saved document, and verify that the "IsSigned" and "IsValid" properties both equal "true",
// indicating that the signature line contains a signature.
doc = new Document(getArtifactsDir() + "DocumentBuilder.SignatureLineProviderId.Signed.docx");
Shape shape = (Shape) doc.getChild(NodeType.SHAPE, 0, true);
