Uses of Class
org.apache.pdfbox.exceptions.CryptographyException
Packages that use CryptographyException
Package
Description
These classes deal with encryption algorithms that are used in the PDF Document.
The PDModel package represents a high level API for creating and manipulating PDF documents.
The encryption package will handle the PDF document security handlers and the functionality of pluggable security handlers.

Uses of CryptographyException in org.apache.pdfbox.pdmodel.encryption
Methods in org.apache.pdfbox.pdmodel.encryption that throw CryptographyExceptionModifier and TypeMethodDescriptionfinal byte[]
StandardSecurityHandler.computeEncryptedKey
(byte[] password, byte[] o, int permissions, byte[] id, int encRevision, int length, boolean encryptMetadata) Compute the encryption key.final byte[]
StandardSecurityHandler.computeOwnerPassword
(byte[] ownerPassword, byte[] userPassword, int encRevision, int length) Compute the owner entry in the encryption dictionary.final 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
PublicKeySecurityHandler.decryptDocument
(PDDocument doc, DecryptionMaterial decryptionMaterial) Decrypt the document.abstract void
SecurityHandler.decryptDocument
(PDDocument doc, DecryptionMaterial mat) Prepare the document for decryption.void
StandardSecurityHandler.decryptDocument
(PDDocument doc, DecryptionMaterial decryptionMaterial) Decrypt the document.void
SecurityHandler.decryptStream

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.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
