PdfFileSecurity

Overview

PdfFileSecurity is a class in Aspose.Pdf FOSS for Java. Inherits from: Closeable.

Provides methods for managing PDF document security: encryption, decryption, passwords, and access permissions.

Properties

Name	Type	Access	Description
`inputFile`	`String`	Read	Returns the configured input file path.
`outputFile`	`String`	Read	Returns the configured output file path.
`document`	`Document`	Read	Returns the bound Document, or {@code null}.
`outputStream`	`OutputStream`	Read	Returns the configured output stream.
`allowExceptions`	`boolean`	Read	Returns whether facade methods should throw immediately when an operation fails.
`encrypted`	`boolean`	Read	Returns whether the bound document is encrypted.

Methods

Signature	Description
`PdfFileSecurity()`	Creates a new {@code PdfFileSecurity} instance.
`PdfFileSecurity(inputFile: String, outputFile: String)`	Creates a facade bound to the specified input and output files.
`PdfFileSecurity(inputStream: InputStream, outputStream: OutputStream)`	Creates a facade bound to the specified input and output streams.
`PdfFileSecurity(document: Document, outputStream: OutputStream)`	Creates a facade bound to the specified document and output stream.
`getInputFile()` → `String`	Returns the configured input file path.
`setInputFile(inputFile: String)`	Sets the configured input file path.
`getOutputFile()` → `String`	Returns the configured output file path.
`setOutputFile(outputFile: String)`	Sets the configured output file path.
`setInputStream(inputStream: InputStream)`	Sets the configured input stream.
`getDocument()` → `Document`	Returns the bound Document, or {@code null}.
`getOutputStream()` → `OutputStream`	Returns the configured output stream.
`setOutputStream(outputStream: OutputStream)`	Sets the configured output stream.
`isAllowExceptions()` → `boolean`	Returns whether facade methods should throw immediately when an operation fails.
`setAllowExceptions(allowExceptions: boolean)`	Sets the exception behavior flag.
`bindPdf(inputFile: String)` → `boolean`	Binds a PDF file to this security facade.
`bindPdf(inputStream: InputStream)` → `boolean`	Binds a PDF from an input stream.
`bindPdf(document: Document)` → `boolean`	Binds an existing {@link Document} to this security facade.
`save(outputFile: String)` → `boolean`	Saves the bound document to a file.
`save(outputStream: OutputStream)` → `boolean`	Saves the bound document to an output stream.
`save()` → `boolean`	Saves the bound document to the configured output destination.
`decryptFile(password: String)` → `boolean`	Decrypts the bound PDF document.
`isEncrypted()` → `boolean`	Returns whether the bound document is encrypted.
`setPrivilege(userPassword: String, ownerPassword: String, permissions: int)` → `boolean`	Sets document privileges using explicit password strings and a raw bitmask.
`setPrivilege(privilege: DocumentPrivilege)` → `boolean`	Sets document privileges using empty passwords.
`setPrivilege(userPassword: String, ownerPassword: String, privilege: DocumentPrivilege)` → `boolean`	Sets document privileges and applies standard encryption using the supplied
passwords.
`encryptFile(userPassword: String, ownerPassword: String, privilege: DocumentPrivilege, keySize: KeySize)` → `boolean`	Encrypts the document using the specified key size.
`encryptFile(userPassword: String, ownerPassword: String, privilege: DocumentPrivilege, keySize: KeySize, algorithm: Algorithm)` → `boolean`	Encrypts the document using the specified key size and algorithm family.
`changePassword(oldPassword: String, newPassword: String, newOwnerPassword: String)` → `boolean`	Changes the document passwords while preserving the current permissions and
algorithm.
`changePassword(oldPassword: String, newPassword: String, newOwnerPassword: String, privilege: DocumentPrivilege, keySize: KeySize)` → `boolean`	Changes passwords and privilege flags using the specified key size.
`changePassword(oldPassword: String, newPassword: String, newOwnerPassword: String, privilege: DocumentPrivilege, keySize: KeySize, algorithm: Algorithm)` → `boolean`	Changes passwords, privilege flags, and algorithm family.
`trySetPrivilege(userPassword: String, ownerPassword: String, privilege: DocumentPrivilege)` → `boolean`	Attempts to set privileges and returns {@code false} instead of throwing.
`tryEncryptFile(userPassword: String, ownerPassword: String, privilege: DocumentPrivilege, keySize: KeySize)` → `boolean`	Attempts to encrypt and returns {@code false} instead of throwing.
`tryEncryptFile(userPassword: String, ownerPassword: String, privilege: DocumentPrivilege, keySize: KeySize, algorithm: Algorithm)` → `boolean`	Attempts to encrypt and returns {@code false} instead of throwing.
`tryDecryptFile(password: String)` → `boolean`	Attempts to decrypt and returns {@code false} instead of throwing.
`tryChangePassword(oldPassword: String, newPassword: String, newOwnerPassword: String)` → `boolean`	Attempts to change password and returns {@code false} instead of throwing.
`tryChangePassword(oldPassword: String, newPassword: String, newOwnerPassword: String, privilege: DocumentPrivilege, keySize: KeySize)` → `boolean`	Attempts to change password and returns {@code false} instead of throwing.
`tryChangePassword(oldPassword: String, newPassword: String, newOwnerPassword: String, privilege: DocumentPrivilege, keySize: KeySize, algorithm: Algorithm)` → `boolean`	Attempts to change password and returns {@code false} instead of throwing.
`close()`	Closes the security facade and releases the bound document.
