Examples of org.pdfbox.pdmodel.encryption.StandardDecryptionMaterial

org.pdfbox.pdmodel.encryption.StandardDecryptionMaterial
Represents the necessary information to decrypt a document protected by the standard security handler (password protection). This is only composed of a password. The following example shows how to decrypt a document protected with the standard security handler:
```
 PDDocument doc = PDDocument.load(in); StandardDecryptionMaterial dm = new StandardDecryptionMaterial("password"); doc.openProtection(dm); 
```
