Encryption

The Encryption property password protects a PDF document and restricts users to viewing, modifying or even printing the document. This function requires a call to SetLicenseKey before it can be used.

Syntax

ActiveX:

DLL:

Parameters

Return Value

Remarks

Encryption Type	Value
No encryption	0
40 bits encryption	1
128 bits encryption	2
256 bits encryption This requires a special license	3

In the case of the evaluation version, the passwords are always set to "aaaaaa" (OwnerPassword) and "bbbbbb" (UserPassword) and cannot be changed.

When the Encryption option needs to be changed for a specific printout and not set as default for all printouts, the FileNameOptionsEx property provides a more efficient way using EncryptDocument, EncryptDocument128 and EncryptDocument256 flags.

However, if the default setting in the Encryption is enabled. It is not possible to generate No Encrypted file programmatically just using FileNameOptionsEx property.

Example

Visual Basic .Net
C#
C++
Java
PowerShell
VBScript
