Assembly

PdfSharp.dll

Typical settings to initialize encryption with. With PdfDefaultEncryption, the encryption can be set automized using PdfStandardSecurityHandler.SetPermission() with one single parameter.

public enum PdfDefaultEncryption

Fields

Default = 1

Use V4UsingAES, the most recent encryption method not requiring PDF 2.0.

None = 0

Do not encrypt the PDF file.

V1 = 2

Encrypt with Version 1 (RC4 and a file encryption key length of 40 bits).

V2With128Bits = 4

Encrypt with Version 2 (RC4 and a file encryption key length of more than 40 bits, PDF 1.4) with a file encryption key length of 128 bits. This was the default encryption in PDFsharp 1.5.

V2With40Bits = 3

Encrypt with Version 2 (RC4 and a file encryption key length of more than 40 bits, PDF 1.4) with a file encryption key length of 40 bits.

V4UsingAES = 6

Encrypt with Version 4 (RC4 or AES and a file encryption key length of 128 bits using a crypt filter, PDF 1.5) using AES (PDF 1.6).

V4UsingRC4 = 5

Encrypt with Version 4 (RC4 or AES and a file encryption key length of 128 bits using a crypt filter, PDF 1.5) using RC4.

V5 = 7

Encrypt with Version 5 (AES and a file encryption key length of 256 bits using a crypt filter, PDF 2.0).
