org.apache.pdfbox.pdmodel.PDDocument.openProtection()
Tries to decrypt the document in memory using the provided decryption material. @see org.apache.pdfbox.pdmodel.encryption.StandardDecryptionMaterial @see org.apache.pdfbox.pdmodel.encryption.PublicKeyDecryptionMaterial @param pm The decryption material (password or certificate). @throws BadSecurityHandlerException If there is an error during decryption. @throws IOException If there is an error reading cryptographic information. @throws CryptographyException If there is an error during decryption.
