Uses of CryptographyException in org.apache.pdfbox.pdmodel.encryption

Methods in org.apache.pdfbox.pdmodel.encryption that throw CryptographyException

Modifier and Type	Method and Description
byte[]	StandardSecurityHandler.computeEncryptedKey(byte[] password, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) Compute the encryption key.
byte[]	StandardSecurityHandler.computeOwnerPassword(byte[] ownerPassword, byte[] userPassword, int encRevision, int length) Compute the owner entry in the encryption dictionary.
byte[]	StandardSecurityHandler.computeUserPassword(byte[] password, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) This will compute the user password hash.
void	SecurityHandler.decryptArray(COSArray array, long objNum, long genNum) This will decrypt an array.
void	StandardSecurityHandler.decryptDocument(PDDocument doc, DecryptionMaterial decryptionMaterial) Decrypt the document.
abstract void	SecurityHandler.decryptDocument(PDDocument doc, DecryptionMaterial mat) Prepare the document for decryption.
void	PublicKeySecurityHandler.decryptDocument(PDDocument doc, DecryptionMaterial decryptionMaterial) Decrypt the document.
void	SecurityHandler.decryptStream(COSStream stream, long objNum, long genNum) This will decrypt a stream.
void	SecurityHandler.decryptString(COSString string, long objNum, long genNum) This will decrypt a string.
void	SecurityHandler.encryptData(long objectNumber, long genNumber, InputStream data, OutputStream output) Deprecated. While this works fine for RC4 encryption, it will never decrypt AES data You should use encryptData(objectNumber, genNumber, data, output, decrypt) which can do everything. This function is just here for compatibility reasons and will be removed in the future.
void	SecurityHandler.encryptData(long objectNumber, long genNumber, InputStream data, OutputStream output, boolean decrypt) Encrypt a set of data.
void	SecurityHandler.encryptStream(COSStream stream, long objNum, long genNum) This will encrypt a stream, but not the dictionary as the dictionary is encrypted by visitFromString() in COSWriter and we don't want to encrypt it twice.
void	SecurityHandler.encryptString(COSString string, long objNum, long genNum) This will encrypt a string.
byte[]	StandardSecurityHandler.getUserPassword(byte[] ownerPassword, byte[] o, int encRevision, int length) Get the user password based on the owner password.
boolean	StandardSecurityHandler.isOwnerPassword(byte[] ownerPassword, byte[] u, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) Check for owner password.
boolean	StandardSecurityHandler.isOwnerPassword(String password, byte[] u, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) Check for owner password.
boolean	StandardSecurityHandler.isUserPassword(byte[] password, byte[] u, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) Check if a plaintext password is the user password.
boolean	StandardSecurityHandler.isUserPassword(String password, byte[] u, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) Check if a plaintext password is the user password.
void	StandardSecurityHandler.prepareDocumentForEncryption(PDDocument doc) Prepare document for encryption.
