Examples of org.pdfbox.pdmodel.encryption.PublicKeyDecryptionMaterial

org.pdfbox.pdmodel.encryption.PublicKeyDecryptionMaterial
This class holds necessary information to decrypt a PDF document protected by the public key security handler. To decrypt such a document, we need:
- a valid X509 certificate which correspond to one of the recipient of the document
- the private key corresponding to this certificate
- the password to decrypt the private key if necessary
Objects of this class can be used with the openProtection method of PDDocument. The following example shows how to decrypt a document using a PKCS#12 certificate (typically files with a pfx extension).
```
 PDDocument doc = PDDocument.load(document_path); KeyStore ks = KeyStore.getInstance("PKCS12"); ks.load(new FileInputStream(certificate_path), password.toCharArray()); PublicKeyDecryptionMaterial dm = new PublicKeyDecryptionMaterial(ks, null, password); doc.openProtection(dm); 
```
In this code sample certificate_path contains the path to the PKCS#12 certificate. @see org.pdfbox.pdmodel.PDDocument#openProtection(DecryptionMaterial) @author Benoit Guillon (benoit.guillon@snv.jussieu.fr) @version $Revision: 1.2 $

        
        PDDocument docOpen1 = PDDocument.load(output);
        
        KeyStore ks1 = KeyStore.getInstance("PKCS12");        
        ks1.load(new FileInputStream(privateCert1), password1.toCharArray());            
        PublicKeyDecryptionMaterial pdm = new PublicKeyDecryptionMaterial(ks1, null, password1);        
        docOpen1.openProtection(pdm);        
        docOpen1.close();


        /* open second time */
        
        PDDocument docOpen2 = PDDocument.load(output);
        
        KeyStore ks2 = KeyStore.getInstance("PKCS12");        
        ks2.load(new FileInputStream(privateCert2), password2.toCharArray());            
        PublicKeyDecryptionMaterial pdm2 = new PublicKeyDecryptionMaterial(ks2, null, password2);        
        docOpen2.openProtection(pdm2);        
        docOpen2.close();
                
    }
